Is it possible to render a SciChartSurface instance to an SVG (scalable vector graphics) file? Preferably, I would like to accomplish this without displaying the surface in a window or dialog.

I have working code to render a surface directly to a bitmap.

RenderTargetBitmap bmp = new RenderTargetBitmap(GraphWidth, GraphHeight, 96, 96, PixelFormats.Pbgra32);
bmp.Render(this.Surface);

BitmapEncoder encoder = new PngBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(bmp));
encoder.Save(myFileStream);

Can the same phenomenon be achieved, but with SVG?

Unfortunately, we cannot support export to SVG. At SciChart we have completely re-written the way you render in WPF, replacing slow vector-graphics for fast bitmap-graphics. Going back to SVG would require going back to Vectors, which would be extremely slow.

The best we can offer now is exporting to bitmap. We have a thread on this topic here:
