This is not currently supported, but it's certainly something we could support with a flag to delay the rendering of the borders. Is there a standard name for this behaviour?

Should be bodgable by extending ScatterSeries and overriding Render so that it performs another render pass with only the outlines, but would need to C&P most of the code to determine the sizes and the markers.

delay the rendering ? use init other renderContext ?

@VisualMelon hi, I found that using SVG rendering to export diagrams is displaying correctly, while using WPF rendering is an error.

Which SVG exporter/renderer are you using?

[flypigeon]

using OxyPlot.Wpf .SvgExporter : OxyPlot.SvgExporter
