Currently, I’m using a uniform heatmap to display images taken from a monochrome camera. I’m using a RubberBandXyZoomModifier to allow to user to zoom in on a region of interest in the image. The SciChartSurface is set to be 640×480 (the image size) and is hosted in a Viewbox, so it’s size scales uniformly with the grid that it’s in. The problem I’m facing is that when I zoom in, the zoomed part of the image stretches to fit the 640×480 size, changing the pixel aspect ratio, but I want the pixel aspect ratio to stay constant so they are all square. What I want to happen is that extra space is added either on the top/bottom or left/right of the zoomed part of the image so the pixel aspect ratio stays constant. See the attached image for a visual explanation. I think I either need to change the SciChartSurface size or the GridLinesPanel size to match the zoomed area size, but I’m not sure how to go about doing that. Is there a way to achieve this? Thanks!

Hi:

My name is Harold Ramírez and I have a question I would like you to answer because I don’t find any doucmentation about it online.

I have a WPF application with several charts, some of them in 3D. These 3D charts have the X axis in horizontal, Y in vertical and the Z in depth. I want only to keep the labels on the X and Y axis, on the left and bottom of the chart.

The only documentation I have found is this page: https://www.scichart.com/documentation/v5.x/webframe.html#Showing%20Axis%20Labels%20on%20one%20side%20of%20the%203D%20Chart.html, and only shows how to make it in XAML, but I need it to do it programatically in C#.

Thank you for your time.

Harold.

Hello,

I’m trying to display a vertical line annotation on a chart using MVVM.

In order to make it work I’ve (All the INotifyPropertyChanged are managed via the BaseViewModel)

public class GraphSurfaceBaseViewModel : BaseViewModel
{
    /// <summary>
    /// A list of annotations
    /// </summary>
    public ObservableCollection<IAnnotationViewModel> Annotations { get; private set; }

 ...
}

I create annotation that way

Graph.Annotations.Add(new VerticalLineAnnotationViewModel()
            {
                X1 = TimeOfComment,
                ShowLabel = true,
                StrokeThickness = 2,
                XAxisId = "Xaxis",
                YAxisId = "Yaxis1",
                AnnotationLabels = new ObservableCollection<AnnotationLabel>() { new AnnotationLabel() {Text = "mon test", LabelPlacement = LabelPlacement.TopRight } }

            });

And the binding to the scichartsurface is :

<s:SciChartSurface   
...         
Annotations="{s:AnnotationsBinding Annotations}"            
</s:SciChartSurface>

I’ve double check that my x axis and y axis have the same ID as the annotation.
The problem is I want to display several annotation labels but they are not appearing. I suspect a problem via the AnnotationsBinding which is not taking the AnnotationLabels from the VerticalLineAnnotationViewModel.

What I got :
enter image description here

What I want (paint skill here):
enter image description here

For the what I want, I can draw a simple vertical bar by settings showLabel = false but I suppose that all the label I previously added to the
AnnotationLabels will not be shown, that’s why I let it.

Thank you for any help.

Hi,

I’m attempting to attach a generic/abstract DataSeries to an INotifyPropertyChanged object. However, the TX, TY generics seem to block me from using it as expected. Can anyone help me out?

internal class DataSeriesAbstract : INotifyPropertyChanged
{
    public string dataName;
    public double lastAppendedTimestamp = 0.0f;

    public List<AbstractChartViewModel> subscribers;

    // gives an error that TX and TY cannot be found
    public DataSeries<TX, TY> realData;
    public DataSeries<TX, TY> Data
    {
        get { return realData; }
        set
        {
            realData = value;
            OnPropertyChanged(dataName);
        }
    }
...
}

Thank you

Hi all,

Why the API’s for iOS, Android and WPF are not identically?
I have seen many samples on the forum, but to adapt it to a different platform is very hard.
A lot of classes are different for each platform.

  • Is there any “comparison” for the different platforms?
  • Is this planned to unify the API’s?

Regards
Urs

Hi, I want to know buffer structure of 2d fastline.

I use very huge data per line.(maybe about 30,000 points/1 sec are appended to a line.)

But Memory usage is different than expected.

I use fifocapacity, and It is realtime graph.

Appending data, the memory usage increases too much.

Especially, It use more memory when drawing more lines.

For example,
Assuming one line uses 100mb, the five lines use 5000mb not 500mb.

Is it right??

I have a chart that has a DateTime XAxis and a NumericYAxis. I want to do something such as FastLineRenderableSeries.GetYValueAt(datetime) yet i can’t find a suitable extension method for such thing. Seems like a fairly simple thing but the documentation does not cover it.

Hi,
I am drawing real-time chart(512 points per second/ 1 line).
My memory usage shape is like a serrated shape…
I just want to use a certain amount that I set.

Is there any solution or option??

We are considering using SciChart (WPF), but only if its performance is ‘reasonable’ across Remote Desktop / or via Citrix Server. Have you addressed the known problems of using WPF applications across RDP / Citrix? If so, could you provide some stats as to the performance across RDP?

The reason we are asking is that our current software in which we are using our own high speed rendering is doing fine with a lot of data on the local machine, but is not doing so well across RDP. This is not a huge surprise given the known issues of WPF and RDP (for example see https://stackoverflow.com/a/1005739/246758). We may need to deal with this slowness as more of our customers are using Citrix-servers to run our software.

Any feedback on performance of SciChart across RDP / or using Citrix would be much appreciated!

I can’t establish a runtime license in my application because the method doesn’t show up in the intellisense.

SciChartSurface.SetRuntimeLicenseKey.

In fact, no methods exist for this class (I’m assuming this is a static class and method). I’m getting this class via…

SciChart.Charting.Visuals.SciChartSurface.

I’m guessing that this is not where this class is located, but I can’t figure out where it is.

I just purchased a license for WPF 2D+3D (Pro) and tried to use a scichartsurface without DirectX and it works fine but as soon as I include

s3D:DirectXHelper.TryApplyDirectXRenderer="True"
                s3D:DirectXHelper.FallbackType="{x:Type s:HighSpeedRenderSurface}"

I get the following runtime error:

System.Windows.Markup.XamlParseException: ‘Could not load file or assembly ‘SciChart.Drawing.DirectX, PublicKeyToken=b55dd9efe817e823′ or one of its dependencies. The system cannot find the file specified.’

What am I doing wrong? I installed the newest Scichart version on the Nuget channel. In Nuget I can see that “SciChart”, “SciChart3D”, “SciChart.DirectX” and a bunch of SharpDX libraries were installed.

Hi,

I am playing with the heatmap chart and stumbled upon an IndexOutOfRange exception when updating the chart.

I initialise my chart where Height=2 and Width=3:

var data = new double[Height, Width]; // 2 rows, 3 columns
double d = 0.0;
for (int y = 0; y < Height; y++)
{
    for (int x = 0; x < Width; x++)
    {
        data[y, x] = d++;
    }
}

heatmapSeries.DataSeries = new UniformHeatmapDataSeries<int, int, double>(data, 0, 1, 0, 1);

Calling the following line returns 5 which is equivalent to getting the value with data[1,2] (all good so far):

dataseries.GetZValue(yIndex: 1, xIndex: 2);

Now let’s update that value to, say 7.1, with:

dataseries.UpdateZValue(xIndex: 2, yIndex: 1, zValue: 7.1);

Executing the above line throws an IndexOutOfRangeException. Looking at the source code, the UpdateZValue() method does:

_zValues[xIndex, yIndex] = zValue;
// ...

No wonder why the exception gets thrown… I reckon it should be _zValues[yIndex, xIndex] = zValue; (xIndex and yIndex swapped).

I’m trying to figure out the best approach to this. Basically I have line series which is defining a limit, may only have points at X=0 & max rather than individual points. My 2nd value I want to fill with one color when it’s below that limit and if it goes above the limit then only the portion above that limit should be colored differently (blue in example).

Anybody able to set me on the right track for this? I can think of ways to do it if I break the 2nd value up and display as two series (would basically be a stacked mountain then. and just limit one to not go above the limit value. Is there a way to avoid breaking this up to separate series and just style it?

I want to implement in scichart3d viewport3d geometry object select
entity object (viewport3d geometry object) selection is not Support.
so i think I tried to put a series in the inside of an object so that I could select it.
but series overwritten with viewport3d object are not selected.
so I made it disappear temporarily when I clicked on an object, but it was not practical enough.

Below is an example I wrote.
I hope I can help you see this.

enter link description here

Is there any other way to implement the ability to select viewport3d geometry objects?

I have a problem with the alignment of the Minor Grid Line.
As you can see on the ScreenShot, the minor lines are not synchronized with the major line. They are not in the same x-axis position.
How can I do this?

Furthermore, I would like to have a dotted line instead of the dotted line. How can I do this?
How can I define the number of points between the major grids? currently there are 15, but I do not define this, it must be determined internally by the SciChart.

Thank you for your support.

Hi, I am currently working with the DataPointSelectionModifier with StackedColumnRenderableSeriesViewModel series. I currently am able to get the data point with the correct values whenever I click on a column but it seems that I am not able to change the selection fill of the column.

All I can seem able to do is changing the color of the whole series, but that is not what I am looking for.

Best Regards.

Hi ,

I am currently using the DataPointSelectionModifier for StackedColumnRenderableSeriesViewModel and I am having an issue trying to have a single selection that is togglable.

I am currently not AllowingMultiSelection so the default value is SelectionMode.Replace, which, in case you click on the same column, it will deselect that column and then select it again. Is there a way around this?

Best Regards.

Hello
I’m working on a WPF app. Everything is OK except that I don’t understand how to render the series above the annotations.
The XAML code is the following:

<s:SciChartSurface Name="sciChartSurface"
                   s:ThemeManager.Theme="SciChartv4Dark"
                   Annotations="{Binding Path=Annotations}"

    /// <returns></returns>
    private AnnotationBase CreateChartAnnotation(Annotation a)

        //not used??
        //ColorToBrushConverter brushConverter = new ColorToBrushConverter();

        annotation = new HorizontalLineAnnotation() { Y1 = a.ThresholdValue.Value };
        annotation.Stroke = new SolidColorBrush((Color)ColorConverter.ConvertFromString(a.Stroke));
        annotation.HorizontalAlignment = System.Windows.HorizontalAlignment.Stretch;
        annotation.IsEditable = false;
        annotation.LabelTextFormatting = string.Format("{0} 0.0", a.Label);
        annotation.StrokeThickness = 2;
        annotation.LabelPlacement = LabelPlacement.Axis;
        annotation.ShowLabel = a.ShowLabel;
        if (a.DashArray != null)
        {
            annotation.StrokeDashArray = new DoubleCollection(a.DashArray);
        }


        return annotation;
    }

I tried to set AnnotationCanvas.BelowChart but the behaviour is very strange: the horizontal annotation line is no more continuous
I attached two jpegs

I have a TabControl that contains a dynamic number of chart panes via an ItemsControl. Inside the ItemsControl’s ItemsTemplate is a single ScichartSurface with bindings to the RenderableSeries, XAxis, YAxes, and VerticalChartGroup.

The xaml looks something like this:

<s:SciChartSurface name="Chart" RenderableSeries="{Binding rSeries}" XAxis={Binding xAxis} YAxes={Binding yAxes} s:SciChartGroup.VerticalChartGroup="{Binding vGroup}">

Within the surface, I have a ModifierGroup that contains (in order) a RubberbandXyZoomModifier (XAxisOnly), MouseWheelZoomModifier, ZoomPanModifier, ZoomExtentsModifier, and a custom mod call TimeSegmentSelectionModifier. All of these modifiers have their ReceiveHandledEvents property set to True, they are all under the same MouseEventGroup, and they all seem to work fine under normal circumstances.

Note: The Rubberband and TimeSegment modifiers are inversely set to Enabled. Meaning, only one of them functions at a time.

My issue is primarily with the RubberBand Mod:

Let’s say I have 5 chart panes being displayed and I want to zoom in; If I click and drag within the 3rd chart, every chart zooms correctly.
If I click withing the 3rd chart, drag the mouse outside of that chart (anywhere else on my screen) and let go, then only charts 1, 2, and 3 are zoomed correctly. Charts 4 and 5 won’t budge and act as if I had merely zoomed to extents.

This happens with any number of chart panes and the issue occurs on whatever pane I happened to be zooming in on.

I’ve been troubleshooting this issue for a few days now and I don’t know where else to look.
Any help is greatly appreciated.

Hello support team,

We have to realize the following request:
– Yt chart with DateTime as X-axis and double values on the Y-axis
– The chart should display a user-defined area on startup (e.g. 20 sec) After the chart has run for 20 seconds ( i.e. 20 seconds), the animated scrolling should start. By default, the chart behaves as follows: The X-axis area fills up to 20 seconds and then starts scrolling. We want the chart to display 20 seconds on the X-axis at the start and fill up.

I am aware that I can implement this behavior myself. However, the question arises whether I can realize this directly with a basic functionality.

Thank you!

Hello,

ColumnChart: Autorange is not working if XyDataSeries contains 1 or 2 items.

The SDK example -> 2D Charts -> Column Chart with little modifications (the complete code is attached):

    private void OnClick(object sender, RoutedEventArgs e)
    {
        using (this.sciChart.SuspendUpdates())
        {
            for (int i = 0; i < ARRAY_SIZE; i++)
            {
                var val = _rnd.Next(-100, 100);
                Debug.WriteLine(val);
                _dataSeries.Update(i, val);
            }
        }
        sciChart.ZoomExtents();
    }

If ARRAY_SIZE is 1; any value; after “click me” button pressed (may be needed to press few times to catch this)
enter image description here

If ARRAY_SIZE is 2; the values are [27, 55]

enter image description here

If ARRAY_SIZE is 3 or more – columns are displayed OK for any values.

If I use

AutoRange="Never" VisibleRange="-100, 100"

this example works OK.

Question: please let me know how to make the ColumnChart working properly for one or two columns and AutoRange=”Always”

Thanks!

All I did was remove the toolbar and a dd a button that copied the image to the clipboard. Yet Somehow the result of what you see while running and what you get from the clipboard are not the same. The lower half of the image you get by rendering to memory is clearly darker. I tried uploading them but could not.

Hi,

I use GradientColorPalette to set the color mapping of Y axis in Waterfall 3D Chart.
I want to fix the color to certain fixed min/max level, e.g. red when y value >= 100, green when y value < -100.
Currently, it seems that color is auto scale to current min/max y value in waterfall.
I try setting VisibleRange of YAxis, but it has no effect on color mapping.

In case of SurfaceMeshRenderableSeries3D, there are Minimum and Maximum properties.
In case of FastUniformHeatmapRenderableSeries, there are Minimum and Maximum properties in HeatmapColorPalette.
Are there any similar min/max properties to use for Waterfall 3D Chart?

Looking up the documentation, I still cannot find the suitable properties to use.
Is there any way to do the min/max color mapping for waterfall chart?

Best regards

Dear all
When the binding data is changed in real time to the ColumnRenderableSeries, the pointer size of the corresponding series is changed to an arbitrary size.
ColumnRenderableSeries wants to know if it can fix the size when the x and z axes are changed in real time.
Or, I want to know if there is a function that can calculate the position of xyz in 3D chart and adjust the height of the corresponding pointer.

Thank you for your reply.

My company is pondering buying the SciCharts suite and using the wpf chart for one of our flagship applications. I have a couple questions about what the control supports. Do the charts support users adding a note (tooltip) to a certain point on the line chart? How it works currently is the user right clicks on the chart, types in the note that they want to display and it creates a tooltip at the current position that they clicked on. Can this happen with SCIChart’s LineChart? We also have a need for them to be able to click on a certain point on the chart and drag the marker to another point and have it show the time between the two points. The last thing we need is to be able to click on a line and show statistics for that line (min, max, average, create data, active or not, formatting formula, etc…). I looked for examples of these and could not find them. Can you tell me if these features exist or are possible to implement dynamically? Thank you.

If I set AutoRange = “Always” myHorizontalLineAnnotation draws fine. When I set it to “Never” – which I want – my HorizontalLineAnnotation won’t draw. How do I do this? ty

Hello!

Is there way to create surfaces in different threads (on the same WPF Window) and then synchronize them via groups – methods SciChartGroup.SetVerticalChartGroup() and MouseManager.SetMouseEventGroup() ? Now i catch threads access error 🙁

Thanks!

I have introduced a real time chart in my WPF Application. The chart starts plotting points from the left of the chart ( close to Y-Axis).

I would like it to start plotting from the right of the chart ( Away from Y-Axis) and as when points start adding up, I would like the points to slide to the left ( Towards Y-Axis).

Similar to how performance tab in Task Manager displays the CPU utilization.

Hi SciCharters,
I would like to create a color coded 2D scatter plot.
My approach is the IPointMarkerPaletteProvider interface. It works, but I have experienced a huge performance difference when I individually colored every datapoint of my 2D chart and using a static color.
When I use the same provider but only a single color there is no performance issue at all.

Here is the relevant code of my PointMarkerPaletteProvider interface:

 public PointPaletteInfo? OverridePointMarker(IRenderableSeries rSeries, int index, IPointMetadata metadata)
    {
            var myMetaData= metadata as MyRecordMetadata;
            var colorBarPosition = GetColorBarPosition(myMetaData.PlotValue);

            _pointMarkerColorOverrides.Fill = _ColorBar[colorMapPosition];
            _pointMarkerColorOverrides.Stroke = _ColorBar[colorMapPosition];
             return _pointMarkerColorOverrides;
    }

The _ColorBar contains only 256 values and the Color is selected according to the myMetaData.PlotValue in GetColorBarPosition().
The series is plotted as expected, but it takes “ages”(seconds for 4000 data points) for rendering it on the chart.
If I replace the assignments of _pointMarkerColorOverrides.Stroke and _pointMarkerColorOverrides.Fill with one static color, there’s no performance issue at all.

I was just curious if that is the expected behaviour? Would it be better (in terms of performance) to switch to another chart type (e.g. heatmap chart) to plot color coded values?

I am have a vertical stacked chart setup which shares the same x- axis ranges. I am trying to find a way to add vertical lines in both the charts at once and further I need the vertical lines to be dragged in sync. When one vertical line annotation is dragged, I need the same movement to happen in the other chart as well. I can share a prototype if you want. Please suggest a solution.

I am trying to call the ZoomBy() method of SciChart control from ViewModel. The ZoomBy() is easily available in the xaml.cs file like below:

// TODO: Need to implement zoom using MVVM
    private void BtnZoomIn_Click(object sender, RoutedEventArgs e)
    {
        TemperatureGraph.ChartModifier.XAxis.ZoomBy(-0.1, -0.1);
    }

The same functionality I need to implement using the ViewModel pattern.

However the ZoomExtents method is easily being called using ViewportManager of SciChart control. E.g. below: XAML file

<RocheButton Name="BtnZoomOut" DockPanel.Dock="Top" Icon="{IconResource Icon=ZoomOut}" HorizontalAlignment="Right" Command="{Binding ZoomOutCommand}" />    
<s:SciChartSurface x:Name="TemperatureGraph" Grid.Column="0" s:ThemeManager.Theme="BrightSpark"  
                           RenderableSeries="{s:SeriesBinding TemperatureGraphViewModel}" DockPanel.Dock="Bottom"
                           ViewportManager="{Binding ViewportManager}">

And the ViewModel Code:

public class TemperatureSummaryGraphViewModel : ViewModelBase
    {
        #region Private Members

        private IXyDataSeries<TimeSpan, double> TemperatureDataSeries = new XyDataSeries<TimeSpan, double>();

        private DefaultViewportManager _viewportManager = new DefaultViewportManager();
        private ICommand _zoomOutCommand;

I’m trying to render Histograms at runtime where the bins’ information like upper and lower bounds and width are known. However when I set the DataPointWidth to 0.2 for example, the bin spacing is different. Here is my code and XAML:

        // We can create a histogram with evenly spaced bins 
        // by specifying the lower bound, the upper bound, 
        // and the number of bins:
        var histogram = Histogram.CreateEmpty(values.Min(), values.Max(), numberOfBins);
        double width = (values.Max() - values.Min()) / numberOfBins;
        histogram.Tabulate(values);

        foreach (var bin in histogram.BinsAndValues)
        {
            XyDataSeries<double, double> dataSeries = new XyDataSeries<double, double>();
            dataSeries.Append(bin.Key.LowerBound, bin.Value);

I’m currently in process of selecting a charting framework. I’ve been evaluating SciChart for some time now and have a few questions.
One of them is how can I automate chart operations: both commands and querying. Do you expose some kind of API for End-To-End tests? I’m specifically interested in this kind of tests.
Thanks?

P.S. Alternatively is there any screenshot-comparing API over the charts? That could be a decisive alternative as well.

Hi,

There are some methods exposed in the API, ZoomBy and ZoomExtent which can programmatically be called from the code behind.
I am binding the series using IRenderableSeriesViewModel in MVVM pattern. Can we zoom the sciChart surface on a button click in ModelView?

Appreciating your help on this.

Thanks

I am looking to do some custom formatting of the Heatmap.

Is it possible to show no text if the values are the minimum, and format these buckets to a predefined colour e.g. transparent?

Then I am only showing those buckets with values.

I am using the HeatmapChartwithText as a basis for my prototype at the moment.

This thread looked promising but wasn’t quite what I was looking for, and this thread was last updated a year ago and couldn’t find anything else on the subject so figured it was worth re-asking…

I refactored from using custom RenderableSeries to a custom RenderableSeriesViewModel which has fixed a refresh bug in the chart:

  public class CustomExclusionRenderableSeriesViewModel : BaseRenderableSeriesViewModel
  {
     public override Type RenderSeriesType => typeof(CustomExclusionRenderableSeries);
  }

However I am invoking MouseLeftButtonUp in the chart code behind and performing a hit test. The HitTest method is not exposed on the BaseRenderableSeriesViewModel:

 private void SciChartSurfaceMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
 {                          
    // Perform the hit test relative to the GridLinesPanel
    Point hitTestPoint = e.GetPosition(this.sciChart.GridLinesPanel as UIElement);

    // Get hit test the RenderableSeries using interpolation
    this.ViewModel.HitTestInfo = this.ViewModel.ExclusionSeries.HitTest(hitTestPoint, true);

Is there any way to get the series instance from the view model & hit test it?

My idea was to have two FastLineRenderableSeries that both share the same XyDataSeries. One series will display the data as-is as an absolute value, while the other will display the same data relative to some arbitrary value. Each series would get it’s own axis.

Is there a way to accomplish what I’m trying to do, or is there another approach that accomplishes the same thing?

The CPU spikes and the app never responds. Any thoughts as to why this might happen?

I’m adding an annotation to a chart with a DateTime x-axis. Without a label the annotation is successfully added. However, if I specify a label I get an InvalidOperationException when Add() is called. The exception message is “The Type this is a test is not a valid Comparable Type”}:

                var annotation = new VerticalLineAnnotation
                {
                    VerticalAlignment = VerticalAlignment.Stretch,
                    ShowLabel = true,
                    X1 = time.DateTime,
                    Stroke = System.Windows.Media.Brushes.Orange,
                    LabelPlacement = LabelPlacement.TopRight,
                    LabelValue = "this is a test",
                    LabelsOrientation = Orientation.Vertical
                };

                MyChart.Annotations.Add(annotation);

The LabelValue is obviously of type string and non-null and indeed of type IComparable. Any reason I can’t add it?

Hi,

Please see the 2 images attached. I would like to reproduce something similar to what’s on the images using scichart ie. being able to select/unselect certain parts of the series by placing a control on certain datapoints (being able to add a checkbox to the surface would be great). What options do I have?

One more question, Is it possible to add a label to LineAnnotations?

Thanks.
