Hi there,
Here is my xaml setting :

 <s:SciStockChart.XAxisStyle>
     <Style TargetType="s:CategoryDateTimeAxis">
         <Setter Property="VisibleRange" Value="{Binding ParentViewModel.XRange}" />
         <Setter Property="AutoRange" Value="{Binding ParentViewModel.AutoRangeX}"/>
     </Style>
 </s:SciStockChart.XAxisStyle>

And I also set, XRange = new IndexRange(0, 9), AutoRangeX = AutoRange.Never, but the chart show like image, always has gap there.

What should I do?

I am considering applying server-side licensing for my javerScript application.

In the document below, there is a phrase “Our server-side licensing component is written in C++.”
(https://support.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)

However, there is only asp.net sample code on the provided github.
(https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Sandbox/demo-dotnet-server-licensing)

I wonder if there is a sample code implemented in C++ for server-side licensing.

Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?

Hi,

I feel this should be obvious but I cannot find the answer in the docs. I have multiple Y axis and I want all of them to start at 0 and autoRange only the max value. Also, the zooming should not be affected, it should have normal behavior. I just want the axis to go from 0 to auto max value when we call ZoomExtents(). The default behavior of the ZoomExtents() is auto min value to auto max value.

Is there any way we can achieve this with SciChart?

Thank you,
Alex

Hi, I have a problem with the Y-axis mouse scroll sensitivity regarding values, if you take a look here, you can see that it will take a lot of separate scrolls to reach the desired Y-axis value
due to a low level of sensitivity
how can I solve this problem

Hello.

I’m facing an issue where a previous team member didn’t deactivate licenses on used devices. The device has now been returned, and deactivation is currently not possible. I need to reuse a project used SciChart. Is there a way to reset the list of all previously activated devices?

Thank you.

I’m new to SciChart and have been following the tutorial provided by SciChart (SciChart WPF 2D Charts > Tutorials > MVVM). Took me hours to make it through the first step in Tutorial 02b – Creating a SciChartSurface with MVVM due to namespace typo in the tutorial, and again I’m now stuck at the very second step.

I cannot replicate the result in Tutorial 03b – Adding Series to a Chart with MVVM. No error found in the output, no binding error whatsoever, but the line is not visible. Also see the attached image comparing what it should look like in the tutorial and what mine looks like.

The project is a direct copy and paste from the tutorial except for the names. I have also cross checked against the code in GitHub. I’ve attached the project as a zip with the bin and obj folders removed.

Hello.
I’m just started to use SciChart and I have a question. How I can mirror XAxis in order to values will be increased from right to left. It is not negative scale but this view is more familiar for users (now I remake the old application). P.S. And be the best if additionally you show me how to make static XAxis with chosen range. I see the example in demo’s “Create Realtime Charts” section (my chart will be real-time too), but my application created via MVVM and I think this example not fully applicable to my case (but I fink after some investigation I will can remake example, but if you help me it be easier).

Hi,
I am writing to request some helps about VisibleRange.

I am drawing simple line graphs using NumericAxis and XyDataSeries<long,double>.
I should control axis range so I used XVisibieRange with Int64Range.
But I have an error that It cannot be applied.

How can I control VisibleRange with long type data??

Hi,

i have a SciChartSurface with DateTimeAxis as xAxis and a NumericAxis as yAxis.
The fifo capacity is 500 points.

Now what i want to archieve is that when i zoom in that the visible range updates in a matter that its moving with the fifo and not to be frozen and at some point in time see how the data points are discarded.
I already implemented a CustomRubberBandZoomModifier which disables autoranging on Zoom and enables it after Zoom to Extents.

How could i archieve this like shown in the attached image?

Thank you already in advance.

Good day,

we are using the VerticalSliceModifier for sorted data and it works very good.

<local:VerticalSliceModifierExt x:Name="SliceModifier">
<s:VerticalSliceModifier.VerticalLines>
    <chartModifier:SnappyVerticalLine x:Name="VerticalLine"
                          ShowLabel="False"
                          X1="0"
                          Y1="0"
                          CoordinateMode="Absolute"
                          IsEditable="True">
    </chartModifier:SnappyVerticalLine>
</s:VerticalSliceModifier.VerticalLines>

Please see the image “Example Vertical Slice Modifier”.

The challange is to have something similar for unsorted data.

One of the issues are multiple intersections. Please see the image “Multiple Intersections” where i would like be able to select what intersections shall be highlighted.

The next challange is the usage of multiple series and synchronization based on a different property (t for time). Please see “Multiple Series” image.

We already have IPointMetadata with X,Y and t to be able to find the data point to highlight.

My question: Is there already some modifier chat can help with this requirements or what would be a clean solution if we need to develop a custom modifier.

Thank you in advance
Paul

Hi SciChart,

We are experiencing a SciChart XPS export issue.

I am using a FlowDocumentPageViewer with a FlowDocument containing SciChart graphs. My goal is to export all pages of the FlowDocument to an XPS file using the XamlRenderSurface to save in vector graphics. However, I’m facing an issue where only the currently selected page exports correctly, while the other pages display empty graphs.

By default, we employ the VisualXcceleratorRenderSurface for all SciChart render surfaces. Before exporting, I programmatically switch them to XamlRenderSurface to save in vector graphics. This approach works well when all the graphs have been rendered on-screen at least once with the new surface type before exporting. However, if a graph hasn’t been rendered on-screen before exporting, it appears empty, and only the graphs from the selected page export correctly. You can find code snippets below.

XAML code:

<s:SciChartSurface
    x:Name="PART_Surface"
    ...
    RenderSurface="{TemplateBinding RenderType, Converter={StaticResource RenderTypeConverter}}"
    ...

Converter:

public class RenderTypeConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        // Set render settings
        return (RenderType)value switch
        {
            RenderType.DirectX => new VisualXcceleratorRenderSurface(),
            RenderType.HighQuality => new HighQualityRenderSurface(),
            RenderType.HighSpeed => new HighSpeedRenderSurface(),
            RenderType.Vector => new XamlRenderSurface(),
            _ => new HighSpeedRenderSurface(),
        };
    }
    ...
}

Export:

private void ExportVector(string fullPath)
{
    // Sets the RenderType to Vector for all surfaces
    // This invokes RenderTypeConverter to set the RenderSurface to XamlRenderSurface
    // Since they are bound in the XAML code
    SetAxesSurfacesRenderToVector();

    XPS_Export_AllPagesOfFlowDocument(fullPath);

    // DirectX is always the default for all surfaces that we use
    ResetAxesSurfacesToDirectX();
}
private void XPS_Export_AllPagesOfFlowDocument(string fullPath)
{
    using (var package = Package.Open(fullPath, FileMode.Create))
    {
        using (var xpsDocument = new XpsDocument(package, CompressionOption.Maximum))
        {
            var xpsSerializationManager = new XpsSerializationManager(new XpsPackagingPolicy(xpsDocument), false);
            var documentPaginator = ((IDocumentPaginatorSource)FlowDocument)?.DocumentPaginator;
            xpsSerializationManager.SaveAsXaml(documentPaginator);

            xpsDocument.Close();
        }
    }
}

The binding and the converter works for all offscreen elements, yet the they won’t take effect until rendered on screen at least once.
I have to select each page manually, after setting all graphs to use XamlRenderSurface, so each would be rendered on screen at least once before the export.

My question is: How can I export XamlRenderSurfaces that are off-screen and haven’t been rendered on-screen before the export process?

You can find an image below showcasing the problem.

Thank you and looking forward to your reply!

Kaloyan Krastev

We’re working on a Nyquist plot using the latest SciChart SDK for WPF.
We have quite a MVVM dependent structure already in place.

We are working with 3D frequency based Complex data. The Nyquist plot would have 2 axes – Y for Imaginary values and X axis for Real values. We apply some averaging and post-processing of the 3D data to put in 2D form and show it in the Nyquist plot.

However, we’d like to be able to scroll the data at certain frequency ranges without showing the actual frequency graph in the plot. Is there a possibility to implement an independent scrollbar containing a averaged magnitude graph (similar idea to the processing of the Nyquist data) over a frequency range? We’d like to scroll this frequency range and on selected range changed to recalculate data in the Nyquist plot.

We have quite an extensive graphing structure implemented already. The main issue I’m currently facing is that the scrollbar is bound to the SciChartSurface and I cannot seem to figure out how to build it more like a “sexy” frequency range selector while staying within the SciChart library? Is there any possibility to not be bound to the SciChartSurface? And of course, the axes are quite different – in the Nyquist we have linear real and imaginary values (-2 to +2, for example) whereas the frequency range would extend much further data-wise (0 – 3000 Hz, for example).

Any help would be appreciated. Feel free to ask for more details.

https://www.scichart.com/questions/wpf/i-want-to-bind-selectedpointmarkers-of-datapointselectionmodifier

Hello.
Referring to the link above, we have modified the ViewModel side to maintain the selection state of chart points.

It works fine for a single chart, but when I have multiple charts, the selection points are interlocked between charts. I would like them to be independent of each other.

I wasn’t sure if there was a problem with my code or with the DataPointSelectionModifier, so does anyone know?

I have attached a code sample and a GIF of a working image.

※To reproduce this, click the three points in order from the top while holding down the control key on “Chart1” to make the three points selected. The color of the points will change from blue to red.
Next, while holding down the control key in “Chart2,” click on the bottom point. Then, in “Chart2,” four points are selected, even though only one point is pressed in total.

That is all. Best regards.

Hi, I’m struggling to reduce times for loading draw (5,000Series x 5,000points) x 10 charts
which is in Scichart example ‘Load 500Seriesx500points’.

1. Present, Loading (5,000Series x 5,000points) x 10 charts consumes about 1 minutes.
   How can i load and draw this more faster?

2. And While in loading, how can i generate and show a Progress bar?

I wanted to experiment with adding a tooltip to the SciChart_ScatterChartPerformanceDemo.

I extended the xaml with

 <s:SciChartSurface.ChartModifier>
            <s:ModifierGroup>
                <s:MouseWheelZoomModifier/>
                <s:TooltipModifier />
            </s:ModifierGroup>
        </s:SciChartSurface.ChartModifier>

However, I have noticed that the tooltip doesn’t seem to react properly to the geometry under the cursor. The tooltip will often show up when the cursor is outside the geometry.

If you use a SquarePointMarker with a width and height of 25, the tooltip pops up even when you’re a fair distance away from the geometry.

The hit detection doesn’t appear to be working correctly?

Edit : Also, it appears I am unable to answer questions here, when I add an answer, it accepts it, but doesn’t show anything?

I’m overriding FastLineRenderableSeries so I can do some custom rendering.

I have a data series defined as :

 var xyDataSeries = new XyDataSeries<double>();
            xyDataSeries.Append(0, 0);
            xyDataSeries.Append(1, 1);
Test.DataSeries = xyDataSeries;

and my chart as :

<s:SciChartSurface Loaded="SciChartSurface_Loaded">
        <s:SciChartSurface.RenderableSeries>
            <customSeriesMvvmExample:FastLineRenderableSeriesEx x:Name="Test" />
        </s:SciChartSurface.RenderableSeries>
        <s:SciChartSurface.XAxis>
            <s:NumericAxis/>
        </s:SciChartSurface.XAxis>
        <s:SciChartSurface.YAxis>
            <s:NumericAxis/>
        </s:SciChartSurface.YAxis>
    </s:SciChartSurface>

And then I override InternalDraw :

public class FastLineRenderableSeriesEx : FastLineRenderableSeries
{
    protected override void InternalDraw(IRenderContext2D renderContext, IRenderPassData renderPassData)
    {
        base.InternalDraw(renderContext, renderPassData);

        using (var brush = renderContext.CreateBrush(Colors.Transparent))
        using (var pen = renderContext.CreatePen(Stroke, true, StrokeThickness, Opacity))
        {

            var xCalc = renderPassData.XCoordinateCalculator;
            var yCalc = renderPassData.YCoordinateCalculator;

            var xCoord = xCalc.GetCoordinate(0.5);
            var yCoord = yCalc.GetCoordinate(0.5);

            renderContext.DrawEllipse(pen, brush, new System.Windows.Point(xCoord, yCoord), 150, 150);

            renderContext.DrawLine(pen, 
                new System.Windows.Point(xCalc.GetCoordinate(0.6), yCalc.GetCoordinate(0)),
                new System.Windows.Point(xCalc.GetCoordinate(2), yCalc.GetCoordinate(1.4)));
        }
    }
}

The problem is that the base.InternalDraw draws the original data series line very nicely with anti-aliasing, but the custom circle I draw has no AA, and the custom line I draw looks very thin?

what’s going on here?

Hi Scichart Team,

I want to add two border lines on the top and left of the chart on the existing theme —“BrightSpark”, I searched and tried some IThemeProvider memebers but have no luck to solve it.

Please find the detail in attached pic, just like bottom and right sides, add two border lines on the other two sides.

Hello Scichart Team,

Can you guys provide me with some guidance to implement a custom IRenderableSeriesViewModel implementation that is supported in MVVM binding in Scichartsurface? Specifically, I’m looking to create a chart series that can be bound to my ViewModel and support custom styling and data handling.

I have tried following the tutorial found here…

Worked Example – CustomRenderableSeries in MVVM
https://www.scichart.com/documentation/win/current/webframe.html#Worked%20Example%20-%20CustomRenderableSeries%20in%20MVVM.html

I was getting a cast error from scicharts. I have attached the picture showing the detailed error.
Concerning the XAML code I have tried both the normal Binding keyword and s:SeriesBinding keyword to the RenderableSeries in the SciChartSurface.

Let me know how to go about this!

Hello,

we are building an application where Charts are created/placed by the user in a form of editor.

We observed that the creation of the first Chart takes between 1 to 3 seconds (depending on the system) but the creation of subsequent Charts takes virtually no time (as it should be).

We assume that the creation of the first Chart involves some kind of time consuming initialization that is later used in the creation of subsequent Charts.

So we have researched if there is a way to do this initialization at the start of our application, so the user is not inconvenienced by a three second waiting time while placing the first Chart.

We discovered the “LoadLibrariesAndLicenseAsync”-function. However, it looks like it has no measurable effect.

Maybe we are using it wrong?

Here is an example code to illustrate the problem in a condensed manner:

Two charts are created and each time the time it takes to create them is measured.

The first creation takes about 1600 milliseconds, the second one only 2.

How can we make both creations only take a few milliseconds?

Thank you.

        // SciChartSurface.SetRuntimeLicenseKey("our key");

         await SciChart.Charting.Visuals.SciChart2DInitializer.LoadLibrariesAndLicenseAsync(
           "our key",
            null); //...does not seem to work

This is my first time in this forum, and I am analyzing SCIChart. I am planning to use it in my software, but there are some questions I haven’t been able to answer yet.
My software is similar to an IDE, where the user can build their custom applications and run on windows environment, but we also provide an option to save all the interface in html and javascript. Since SCIChart provides not only WPF Charts but also javascript Charts, I would like to know the following:

1- Does the javascript charts have the same functionalities as the wpf charts? XY Charts or Pie charts for example, will they have the same functionalities in WPF and Javascript ?

2- Does the appearence of the charts in WPF and Javascript are the same? Do they look exatcly the same?

I believe these are my biggest doubts so far. Thanks in advance !!

Hi,

When hovering mouse over a graph, the box that appears showing the name and value gets cut off instead of flipping to remain in the area.

Can you please help me to overcome this issue or if any, idea or lead much appreciated. Please let me know if you need more information.

Please find the screenshot for your reference.

Hello,
I’m using SciChart in our WPF project. And we are Keeping Series and Annotations as RadObservableCollection(from Telerik) instead of ObservableCollection to get the benefits of RadObservableCollection. But when I’m adding or deleting data from RadObservableCollection it does not affect in charts. Does SciChart work with RadObservableCollection ? I’ve explored your examples and wasn’t able to found examples with RadObservableCollection.

Requirements:

• Main graph updates based on the data from the selected Item.
• The data and styling is independent and the style is dynamic global style for all Items.
• The data for the graphing that is Data Series is binded to DataSet which is of type XYDataSeries<DateTime, double>.
• DataSeries data is obtained from the datacontext which implements INotifyPropertyChanged

Problem:

• The databinding is not dynamic and the data series is not updated when the selection changes.
• The initial data selection is reflected but any subsequent data changes are not reflected on the sci chart surface.
• This behavior was only for the Dataseries binding and it was verified using a textbox which binds to the count of the DataSet and this updates as the selection changes but not the dataseries.

Please suggest a work around or an alternative solution so that I can predefine axes and series but swap out the data based on the selected Item. Please see the attached xaml code below.

                            Foreground="Black"/>
    </Grid>

I’m having issues with displaying my vertical annotations on my chart. Below is the code for creating the annotation and adding it to the chart.

var annotationLine = new VerticalLineAnnotation();
annotationLine.XAxisId = XAxisID;
annotationLine.YAxisId = YAxisID;
annotationLine.Stroke = new SolidColorBrush(Colors.Blue);
annotationLine.StrokeThickness = 2;
annotationLine.IsHidden = false;
annotationLine.AnnotationCanvas = AnnotationCanvas.BelowChart;
annotationLine.Y1 = 0;
annotationLine.Y2 = ControlHeight;
annotationLine.X1 = xValues[i];
Surface.Annotations.Add(annotationLine);

I have verified that the XAxisId and the YAxisId are correct and match the id of the only axes that I have on the chart
I have verified that the xValues[i] is a valid value on the chart and within the bounds of the viewport

The tricky part here is that I am reading live streaming EEG data from a device and inserting manual triggers into the data. This works fine and the annotations appear in the chart as they are within the bounds of the chart.
I then record that data to a file (currently csv but will be doing EDF as soon as I get this figured out) where the annotation data is present (verified)
It’s when I try to read the file into my application that I can’t get the annotations to appear on the SciChart. I’m using the code above for both the live streaming data (working) and the file reading (not working) so I’m really baffled by this and could use any insight anyone has.

Thank you
