Hi,

I see one can set an optional PointMarker in FastErrorBarsRenderableSeries. I thought doing so would cause the markers to be drawn at the data points. But this isn’t happening. And in the ErrorBars demo code, you define a separate XyScatterRenderableSeries to draw the data points.

What’s the preferred way? Obviously I can use both an XyScatterRenderableSeries and a FastErrorBarsRenderableSeries, but I’d rather just have one if it can draw both.

Thanks,
–George

Hi George,

BaseRenderableSeries has the PointMarker property. That does not mean that all series support drawing pointmarkers.

In actual fact, FastErrorBarsRenderableSeries does not draw a pointmarker. It could be made to, very easily, if it would make life easier!

For now, the best accepted workaround is to draw a separate scatter series and error bars as per our example.

Hope that helps,

Andrew

OK, thanks. I’m happy to draw a separate scatter series for now.

Note, however, that the following statement (with CAPS added by me), which I found in the online documentation (scichart.com/documentation/Abt.Controls.SciChart.Wpf~Abt.Controls.SciChart.Visuals.RenderableSeries.FastErrorBarsRenderableSeries.html), seems to imply that the pointmarkers would be drawn if the BasePointMarker object is created.

“A RenderableSeries HAS a Abt.Controls.SciChart.Model.DataSeries.IDataSeries data-source, MAY HAVE a Abt.Controls.SciChart.Visuals.PointMarkers.BasePointMarker point-marker, and draws onto a specific … “

Thanks,
