New Post: Printing in WPF with XPS/PrintVisual

Thank you for your great information!
When I try to use 2014.1.231.1 from NuGet it works fine.

I checked changing point roughly. Cause is probably in InvalidatePlot() (Plot.cs or PlotView.cs).
From following version of source code, it has not rendered if it's not receive Loaded event.

This modification is for performance issue.

So... I added uncool code as following it seems be working on latest version of OxyPlot.
"graph" is name of Plot object (<oxy:Plot x:Name="graph">)

    dpc.Measure(new Size(dialog.PrintableAreaWidth, dialog.PrintableAreaHeight));
    dpc.Arrange(new Rect(new Point(0, 0), dpc.DesiredSize));
    dpc.graph.RaiseEvent(new System.Windows.RoutedEventArgs(OxyPlot.Wpf.PlotView.LoadedEvent));   
    dpc.UpdateLayout();

or

    dpc.Measure(new Size(dialog.PrintableAreaWidth, dialog.PrintableAreaHeight));
    dpc.Arrange(new Rect(new Point(0, 0), dpc.DesiredSize));
    dpc.graph.IsRendering = true;
    dpc.graph.InvalidatePlot(true);
    dpc.graph.IsRendering = false;
    dpc.UpdateLayout();

Of course this is not correct way... But currently it may be only way.
It should be modified or extended for our case.
