Chart printing

Hi David,

The Legend needs to be in the visual tree of the SciChartSurface in order for SciChartSurface.ExportToBitmapSource() to export it. There are several ways to achieve this:

1. Include SciChartLegend inside the visual tree of the SciChartSurface by using our LegendModifier.ShowLegend=”True” API.
2. Include SciChartLegend inside the visual tree of the SciChartSurface by using a CustomAnnotation to host a SciChartLegend control
3. Export a control higher up the visual tree (e.g. a Grid which contains both SciChartSurface and SciChartLegend) using the WPF RenderToBitmap feature.

I would personally recommend (1) as this is our supported API for printing a legend, and the easiest to achieve, but any of them will work!

For more info on the LegendModifier and SciChartLegend API see here.

Best regards,
Andrew
