Exporting Empty Plot Images in WPF?

[Guest Micheal]

I have a Contour Plot which I am trying to export to an image. My problem is, the exported image is often an empty image or the image has outdated data. The plot has not finished rendering when I to export it. How do I determine if the plot has finished rendering? Is there a bit I can check or an event I can subscribe to?

 

// Update plot data.

ContourPlot.ItemsSource = Data;

 

// Wait until rendering has finished?

 

// Capture image of plot.

ContourPlot.Export(FileFormat.Bitmap, memoryStream, exportSettings);
