Question

I have a problem with chart export. I´m using MS Chart (System.Windows.Controls.DataVisualization.Toolkit)

I can create graph, but cannot export/save to image. I sae somewhere method chart.SaveImage(…), but I can find it.

There is chart definition:

<DVC:Chart Name="mcChart" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="2,2,2,2" Height="Auto" Width="Auto" DockPanel.Dock="Left" MinWidth="200" />

and here a picture what I see when I call chart from C#, there is no SaveImage:

Please can you somebody help me? Am I missing some extension?
Thaks a lot!

It looks like there’s nothing built in.

There’s a post on the MSDN Forums that gives a solution. You have to create a RenderTargetBitmap and use that:

RenderTargetBitmap renderBitmap = new RenderTargetBitmap(
    (int)chart1.ActualWidth,
    (int)chart1.ActualHeight,
    96d,
    96d,
    PixelFormats.Pbgra32);

renderBitmap.Render(chart1);
