I have a XYRenderableDataSeries with point markers with a fill color.

I also have a DataPointSelectionModifier which allows me to select clusters up to 5 from the series.

I want that when I select a cluster from the series, the points selected from the series should be colored for that specific cluster. i.e. all the cluster colors should be different. Also, when I select another cluster, the colors in the points selected from 1st cluster or other clusters should be preserved.

Here’s the XAML code :

<s:XyScatterRenderableSeries DataSeries="{Binding ScatterData}">
                        <s:EllipsePointMarker  Width="3" Height="3" Fill="#AAFFFFFF" Stroke="SteelBlue" StrokeThickness="2"/>
                        <s:EllipsePointMarker Fill="{Binding ClusterColor, Mode=TwoWay}"
                                              Height="12" />

                    <s:DataPointSelectionModifier Name="PointMarkersSelectionModifier"
                                                  IsEnabled="{Binding IsManualClustering}"
                                                  SelectionStroke="#009E9C9C" />
                    <s:MouseWheelZoomModifier IsEnabled="True" />
                    <s:RubberBandXyZoomModifier IsEnabled="False" />

I tried to find examples but could not find any. Please let me know if we can reach a solution to this in some way.

Thank you.

When I apply the cross marker type to a scatter plot, it’s not centered correctly. It gets more off-center the thicker the stroke becomes. This tends to be the case for any mark that uses the strokeStyle parameter.

This is actually visible in the example app under “Using PointMarkers”. In the attached screenshot of the example app, I increased the cross marker thickness to 15 to show how off-center the cross is to the line. This becomes a bigger issue in a scatter series as there’s no line to reference of where the point should actually be.

Hopefully there’s a way to fix this, but if not, any help on how to apply a corrective offset would be great.

Thanks in advance for any guidance!

Is it possible to plot a continuous vertical line as part of data point markers in line graph? I have used sprite to render text for data points. Now I want to draw a vertical line starting from data point till the peak apex to show which peak it is pointing to. The text labels in point markers are shifted to upward for some peaks to avoid collision and therefore there is a gap between peak apex and the point marker. So this requirement. I tried so far with OR symbol but it is displayed as a vertical dotted line when multiple OR symbols are placed one below another.

Hi All,

We have included in our wpf chart vertical slices to show markers on data series, but when a vertical slice is added, one marker per series is shown at the same time.
Is it possible to show only one marker per series and per vertical line annotation? We want to add serveral vertical slices, and each one has a marker to only one series.
Please find attached two pictures: the first one represents what we have, and the second one represents what we need.

Thank you in advance

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++.”

However, there is only sample code on the provided github.

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?
