I am facing the following two issues related to application crash and unable to perform 3d object rotation in release mode.

Issue 1: Application Crash
I am using PointLineRenderableSeries3D object to render the Data series points.
I have a timer which ticks every 1 sec and have new data series points with some rotation of previous values.
Hence will try to add new points on every 1 sec to the same object data series

timer1.tick +=(() => {
// rendererUpdate is object of PointLineRenderableSeries3D

        using (rendererUpdate.DataSeries.SuspendUpdates()) 
            {
              var newData = GetNewPointsWithRotation( rendererUpdate.DataSeries, 30);//30 is angle of rotation for older points
                rendererUpdate.DataSeries = newData;
            }

}

Issue 2: When i run the application in release mode, i am unable to perform manual rotation using mouse dragging for the 3d sphere FreeSurfaceRenderableSeries3D object SurfaceMesh referred in the code.
When the application is running in release mode , i tried to drag rotate the 3d shape, but the 3d object is not responding to the mouse drag event (Press hold mouse left button and drag).

Code refers .jpg file, Please refer any local jpg file to repro the issue.

Please suggest the possible reasons and fixes of the same.

I am using heatmaps in my application and would love to use the same color scheme that is used for those also in my xyz scatter plots. I know how to make palette providers I just don’t know how to get a specific color that is defined by a lineargradientbrush (defined in xaml) for a specific (relative value? 0.0-1.0 ). Is this possible?

Hi,

I am trying to create a chart with additional information, similarly as discussed in this question:
https://www.scichart.com/questions/question/correlating-metadata-with-datapoints/
It works fine for simple information, such as enums, that I can cast into a double (see also the example provided in the question mentioned above).

However it seems that there is a restriction on the generic class XyzDataSeries.
Whenever I try to use a different data types for TY and TZ

XyzDataSeries<DateTime, double, int>

I get the following exception at runtime:

SciChartSurface didn’t render, because an exception was thrown:

Message: Das Objekt des Typs "Abt.Controls.SciChart.Wpf.StoreEditor1[System.Int32]" kann nicht in Typ "System.Collections.Generic.IList1[System.Double]" umgewandelt werden.

  Stack Trace:    bei Abt.Controls.SciChart.Wpf.NetworkResolver1.Execute(ResamplingMode resamplingMode, IndexRange pointRange, Int32 viewportWidth, Boolean isFifo, Boolean isCategoryAxis, IList xColumn, IList yColumn, Nullable1 dataIsSorted, Nullable1 dataIsEvenlySpaced, Nullable1 dataIsDisplayedAs2d, IRange visibleXRange)

   bei Abt.Controls.SciChart.Wpf.MethodManager.RenderLoop(IRenderContext2D renderContext)
   bei Abt.Controls.SciChart.Visuals.SciChartSurface.DoDrawingLoop()

Sorry for the german. The message translates to:

The object of type [...] cannot be casted into type [...]

I’m quite confused about this. It works nicely, if I use the same data types for TY and TZ .

XyzDataSeries<DateTime, double, double>
XyzDataSeries<DateTime, int, int>

This is not what I would expect from a generic type with three types.
If the types for Y and Z values need to be of the same type, the class should rather look something like this: XyzDataSeries<TX, TYZ>.
The API documentation does not mention anything about this. It only states that the types need to be IComparables, which seems not the full truth.

This is a problem for me, because I have more complex metadata than a double, which I want to reference over the Z value.
But I don’t want to use an index of type double. I’d rather use a GUID or even add the metadata object itself as Z value.

Is this by design or is this something that could be fixed in the future?

Do you have a suggestion how to best reference point related metadata (without having to implement my own DataSeries)?
