In the online demo the Stacked side by side column chart says,
“The StackedColumnRenderableSeries can be used to render columns stacked one above another, side by side, or a Left or Right aligned Bar Chart.”
I’m just wondering how to tell the chart to stack side by side versus one above the other, etc.
Thanks.

I have a custom label formatter which only takes int and covert to string. But for Histogram I need to plot X values with double values. So i cant use that Custom label formatter.

Hallo,

I use the Mousewheelzoommodifier to zoom into the chart. How can i prevent the zoom to zoom into a minimum giving range?

Hi i am new to SCiChart and i was wondering if there is an option to double click on screen and make it full screen or maybe some sort of un-dock it or open it in new window full screen?
Thx

Hi,

I’m using 2 annotation markers, one horizontal and one vertical.

In xaml:

            <SciChart:SciChartSurface.Annotations>
                <SciChart:HorizontalLineAnnotation HorizontalAlignment="Stretch" IsEditable="True" LabelPlacement="Axis" LabelTextFormatting="0.0" ShowLabel="True" Stroke="Orange" StrokeThickness="2" Y1="{Binding Path=UpRightMarkerYPos, Mode=TwoWay}" IsHidden="{Binding Path=TimeChartMarkerIsHidden}"/>
                <SciChart:VerticalLineAnnotation VerticalAlignment="Stretch" IsEditable="True" LabelPlacement="Axis" LabelTextFormatting="0.0" ShowLabel="True" Stroke="Orange" StrokeThickness="2" X1="{Binding Path=BowMarkerXPos, Mode=TwoWay}" IsHidden="{Binding Path=TimeChartMarkerIsHidden}"/>
            </SciChart:SciChartSurface.Annotations>

I’ve set the LabelPlacement on Axis, so I expect that the labels will not be drawn over the graphical data.
It works fine for the Vertical one, but the horizontal marker will display the label over the data, so I can’t see a part of my graph anymore.
How can I position the label so it will not be on top of the graphical data?

Thanks,

In the oil industry a well survey is usually displayed by a series of points connected by arcs. An arc is very close to the actual path a drill will take between points on a survey. Survey points are about 90 feet apart, so connecting them with a straight line looks ugly. Which method should I override to accomplish this?

If I get ambitious, I may also consider using Bezier curves to connect points, as this could be useful to represent geological boundaries as a background for my well survey plots.

I have attached a picture showing the type of plots I need to make. The red line is a survey and the background represents geological layers. The survey is presently connected with straight lines, which makes it difficult to determine precisely where the survey intercept the boundaries.

  <s:SciChartSurface x:Name="sciChart" Grid.Row="0"

                     </s:SciChartSurface.Annotations>
    </s:SciChartSurface>

How can I make BoxAnnotations editable?
I can’t move the boxes in the chart.

I am working on an application where I have multiple XY data series. For one of the series, we are producing annotation data for some of the points. There are 8 different types of annotations that can be created. Based on the response you gave to a previous question, I am creating the annotations as separate data series instead of as actual annotation objects since there are thousands of them. Performance starts to suffer as the number of annotations increases.

The issue I’m running into now is the number of series is now 14 which is unwieldy for displaying in a legend. My current legend is horizontally oriented as shown in the attached image. I would prefer that the user not have to scroll to view all of the legend items and am trying to figure out how to achieve that.

Is there a way to specify a fixed width for the legend and have items wrap to a new line if there is not enough room for them? I didn’t see that as being an option for the standard legend template.

Also, is there a way to use multiple legends for a chart? Ideally it would be nice to split the series that are associated with annotation data into their own legend instead of mixing them in with the legend for the normal data. The SeriesInfo object doesn’t appear to have any property that would allow me to categorize the data.

Thanks,
Scott

Hello there,

I want to switch (per ComboBox) between the data-values at the x-axis:
1. Display data index[x]
2. Display time[x]
3. Display another calculated value[x]

With LabelFormatter it works but there is an issue, My Series0 Time[x] at Index0 is not Series1 Time[x] at Index0. So if I display both series and have (1.) ‘data index’ selected than it works. If I have (2.) ‘time’ selected, it doesn’t because the Series0 Time[x] at Index0 is not Series1 Time[x] at Index0.

How can I solve this?

Hello,

I’d like to have some kind of highlight functionality for a chart as shown in the attached image. Actually it’s exactly what a ScrollBar control does for an overview, but without changing the visible range. Is there any way to (ab)use the ScrollBar for functionality like this? If not, can you perhaps give me some pointers on how you would implement something like this. Or if there is something similar in SciChart I missed?

Do you know a good way to print the hole chart to a printer?
Our first solution is to create a PNG from the chart and paste it into a PDF. But I have to stretch/resize the PNG to the paper size.
It exist a good way to direct paint?

Thanks for helping?

Is it possible to run two versions of SciChart at the same time? I wanted to create a new project in my codebase using the new SciChart version 2.1, without having to upgrade my other projects referencing 1.6. Of course, I now get version conflicts in my final build. Renaming the DLL did not work, is there a way around this?

Hi,
I have done everything possible, but I can’t seem to get the vertical slice modifier to appear. I have wired the function just how the ‘InspectDataPoints => Create Verticle Slices’ SciCharts Example.

Unfortunately, it just doesn’t seem to work! Nothing is popping up when I press the ‘Add Slice’ button. The only difference with the example from SciCharts is that I am using a DateTime Axis.

private void OnCreateSliceClick(object sender, RoutedEventArgs e)
        {
            MouseButtonEventHandler mouseClick = null;
            mouseClick = (s, arg) =>
            {
                this.MouseLeftButtonUp -= mouseClick;
                hintText.Visibility = Visibility.Collapsed;
                var mousePoint = arg.GetPosition((UIElement)this.sciChart.GridLinesPanel).X;

                var slice = new VerticalLineAnnotation()
                {           
                    //X1 = new DateTime(2012, 1, 7, 8, 0, 0),
                    X1 = this.sciChart.XAxis.GetDataValue(mousePoint),
                    Style = (Style)Resources["sliceStyle"]
                };

                sliceModifier.VerticalLines.Add(slice);
            };

            hintText.Visibility = Visibility.Visible;
            this.MouseLeftButtonUp += mouseClick;
        }

And then I tried changing the Date Axis using the following code

var mousePoint = arg.GetPosition((UIElement)this.sciChart.GridLinesPanel).X;
var categoryCoordCalc = sciChart.XAxis.GetCurrentCoordinateCalculator() as ICategoryCoordinateCalculator;
var dataPointIndex = (int)categoryCoordCalc.GetDataValue(mousePoint);

unfortunately, the ‘categoryCoordCalc’ value returns a null!!!

I am so stuck!! Please help me!

Hi!

Connecting to my latest reply on this thread
https://www.scichart.com/questions/question/strange-behaviour-of-collapsing-panes#sabai-entity-content-8887
I still can’t make panes disappear correctly with multiple panes.

Here is the sample project demonstrating what you proposed on the previous thread, the first chartpane is shown but the panes do not resize.
https://drive.google.com/open?id=0B19IHNOVxrKCR21aeG4tOHlRNmM

Please make this project work as expected (i.e. there is 3 panes in the list, but only the second displayed in the list on the area of the 3 panes) to show me, how this works.

thanks.

Hi,

How can I change the colour bar of column chart individually?
I need to create a non linear column chart and every bar should have their own colour that correspond to X values.

Hi,

I created a chart legend based on the online example. I have three data series: an XyScatterRenderableSeries, a FastColumnRenderableSeries, and a FastLineRenderableSeries. The plot itself is fine. But the legend isn’t. In addition to the checkboxes bug (I don’t need these and so have set ShowVisibilityCheckboxes=False, to no effect), I’m seeing color samples for the scatter and column data, but nothing for the line. All three series names appear as expected, but I’m missing the color sample for the line plot. What’s up?

Thanks,
–George

I have a class that extends the IPointMetadata interface that I append in my XyDataSeries data. What I would like to do is create a point marker based off this metadata.

For instance, say I have a property called Shape in my metadata that contains values of Circle, Triangle, Star. I want to be able to create those point marker shapes on the same series of data.

I tried creating my own marker by extending the BasePointMarker class, but I wasn’t able to find a way to get to the metadata.

Hi,

Can I write SciStockChart with DateTimeAxis like:

        <s:SciStockChart SeriesSource="{Binding ChartManager.ChartData, 
                                                UpdateSourceTrigger=PropertyChanged, 
                                                Mode=TwoWay}" 
                         x:Name="SciChart"
                         YAxes="{Binding ChartManager.YAxes}"
                         s:ThemeManager.Theme="Chrome">
            <s:SciStockChart.XAxis>
                <s:DateTimeAxis DrawMinorTicks="True" 
                                DrawMinorGridLines="True" 
                                VisibleRange="{Binding ChartManager.XVisibleRange, 
                                                       UpdateSourceTrigger=PropertyChanged, 
                                                       Mode=TwoWay}"
                                DrawMajorGridLines="True"/>
            </s:SciStockChart.XAxis>
        </s:SciStockChart>

because I have exeption “Axis type DateTimeAxis requires that DataRange and VisibleRange is of type Abt.Controls.SciChart.DateRange”. The XVisibleRange is a IRange type.

Thanks,
Arthur

I’m trying to create a few ChartSurface’s which show same elements but with different visible ranges.
If i share DataSeries by binding to SeriesSource this works. But if i try to binding Annotations to a few ChartSurface’s i see annotations only on last chart. If i manually create copy of annotations that everything works but takes a long time.
Is there any way to binding Annotations to a few Charts?

Hi,

I’m having an exception thrown when I try to dynamically add an annotation. I’m using the example on your site as reference.I’m sure its something I’m overlooking. But I can’t figure out what it is. I have attached my code here, can you tell me what I’m doing wrong here. I’m trying to add a Line annotation when the user clicks on the context menu.

Thanks,
Deepak

I need numAxis.MajorStartIndex = 1;

XValue is sequentially

 public class CustomAxis : NumericAxis
    {
        public override string FormatText(IComparable value)
        {
         ...
        }
    }

Hello,

I am evaluating SciChart (for info : v 2.3) for integration into a WPF application. For the application is important that the user can interact with the chart.

So I have been trying to get that working with SciChart : with the MouseWheelZoomModifier we can use the mouse wheel to zoom the chart and with ZoomPanModifier we can use the left-mouse button to pan the chart. Excellent !

But then we would like to have the same behavior on the axes : Mouse wheel to zoom an axis and left-mouse button to move it up and down. Until now I found only the XAxisDragModifier to make an axis interactive but that has a quite different behavior.

So my question is : How can I get the same zooming and panning behavior on the axes ?

thanks in advance for any help,

Hello,

I’m using v3.2 SciChart and cannot figure with this problem:

    <SciChart:SciChartSurface x:Name="sciChart">
        <!--  Create X Axis  -->
        <SciChart:SciChartSurface.XAxis>
            <SciChart:NumericAxis   AxisTitle="{Binding XAxisLabel}"   VisibleRange="-20, 50"/>
        </SciChart:SciChartSurface.XAxis>
        [...]
    <SciChart:SciChartSurface/>

It seems that negative values are not displayed correctly, it’s showing these data:
-2 -1 0 10 20 30 40 50

If I set textFormatting to “#.0”, it shows
-20, -10, ,0 10,0 20,0 30,0 40,0 50,0

It’s like negative sign is considerate as a digit.

Hi Support Team,

I am a SL developer and i am trying to save the scichart surface as a png file.

I have seen you example “First download the source code, you can find i.e. here: ScreenshotsXpsAndXLabels.zip”

but unfortunally it only works in Wpf , any suggestions would be appreciated.

Cheers

Now I am trying to add MVVM bindings for a Chart Legend

I have

        <SciChart:SciChartSurface x:Name="sciChart" DataSet="{Binding DataSeriesSet}" 
            SciChart:ThemeManager.Theme="Oscilloscope" 
            Grid.Row="1" 
            RenderableSeries="{Binding RenderableSeries}"
            ChartModifier="{Binding ChartModifier}"
            XAxis="{Binding XAxis}" 
            YAxes="{Binding YAxes}">
                   </SciChart:SciChartSurface>
        <SciChart:SciChartLegend x:Name="legendControl" Grid.Row="1" Margin="23,23" ShowVisibilityCheckboxes="True" LegendData="{ Binding LegendDataSource,  Mode=OneWay}"/>

and in My ViewModel

        public AnalogueChartViewModel()
        {
            XAxis = new DateTimeAxis
            {
                VisibleRange = RangeFactory.NewRange(DateTime.Now.AddDays(-2), DateTime.Now),
                DrawMinorGridLines = false,
                AxisTitle = "X-Axis"
            };
            RenderableSeries = new ObservableCollection<IRenderableSeries>();
            YAxes = new AxisCollection();
            DataSeriesSet = new DataSeriesSet<DateTime, double>();
            var xAxisDrag = new XAxisDragModifier();
            var zoomExtents = new ZoomExtentsModifier();
            var rubberBandZoom = new RubberBandXyZoomModifier();
            var panModifier = new ZoomPanModifier { ExecuteOn = ExecuteOn.MouseRightButton };
            _legendDataSource = new LegendModifier { GetLegendDataFor = 0 };

            ChartModifier = new ModifierGroup(xAxisDrag, zoomExtents, rubberBandZoom, panModifier, _legendDataSource);

        }

        private LegendModifier _legendDataSource;

        public LegendModifier LegendDataSource
        {
            get { return _legendDataSource; }
            set 
            { 
                _legendDataSource = value;
                OnPropertyChanged("LegendDataSource");
            }
        }

But not sure how to bind to the LegendData

Sorry I keep troubling you, but after all this there should be some good MVVM code for others to follow too.

Is it possible use SciChart to rotate the point markers on chart by a z value? I’d like to produce a chart similar to the attached wind chart sample from the weather underground website.

I have a problem with FastColumnRenderableSeries. It automatically sets min range on Y scale as lowest value of data. But I need min range on Y scale to be 0. How can I achive that easily?

Additional question: How may I set max value of Y scale? In case if there are rare occasions of extraordinary huge volume periods, which would make all other volumes look tiny.

Hi,

I’m trying to set the Visible Range of a CategoryDateTime Axis and its throwing an “Object must be of type DateTime” exception. Can you tell me whats wrong here

var scs = new SciChartSurface();
scs.XAxis = new CategoryDateTimeAxis() { DrawMajorGridLines = false, DrawMinorGridLines = false,AutoRange=AutoRange.Never };
scs.YAxis = new NumericAxis() { Id = "Y1", DrawMajorGridLines = false, DrawMinorGridLines = false };
scs.Style = (System.Windows.Style)this.chartForm.sciChartControl.Resources["SciChartSurfaceStyle"];
DateTime startDate = new DateTime(2003, 9, 1);
DateTime endDate = new DateTime(2004, 1, 31);
scs.XAxis.VisibleRange = new DateRange(startDate, endDate);

The exception gets thrown on the last line. I also tried populating the series before I called the visible range, but it has not effect on the exception.

Thanks,
Deepak
