SciChart supports exporting to BitmapSource at a specific size, however, this feature does not work for us because we are using custom types for our chart annotations, and we get the following error:
“Please be advised that SciChart doesn’t handle serialization of objects with properties of interface type, collection type or custom type. You need to implement IXmlSerializable in such objects to have them handled properly.”
We haven’t found any example of how to implement IXmlSerializable in on custom type, and were wondering if some guidelines about what is needed to implement that interface could be provided.
The custom type that we are using is an AnnotatedPointMarker, which inherits the sci chart interface IPointMarker. It consists on a square, marking a data point, plus a text annotation on top, and a small line joining the square and the text.
After updating to 220.127.116.1157, all axis labels are missing when exporting graph using SciChartSurface.ExportToBitmapSource(true, size). Reverting back to 18.104.22.16880 solves the issue.
When using the SciChartSurface.ExportToBitmapSource(useXamlRenderSurface: true) to export graph at large size for printing (e.g. at 600 DPI, when the screen is at 96 DPI), the grid lines and axis tick lines do not scale, and point markers are missing. Text, StrokeThickness of line series and legends are shown correctly.
Is it an issue in the renderer? Or is there any setting for the renderer to render them correctly?
Params of the attached graph:
LineSeriesStyle.StrokeThickness = 2,
MajorTickLineStyle.StrokeThickness = 1,
MinorTickLineStyle.StrokeThickness = 1,
MajorGridLineStyle.StrokeThickness = 1,
EllipsePointMarker.StrokeThickness = 1, Width = 6, Height = 6
