Forgive me for being a little naive perhaps, but it seems that System.Windows.Controls.DataVisualization.Charting has vanished from VS2010, and blend 4. I’m trying to make a bar graph with a line overlayed, but can’t even get started because I can’t find the appropriate controls.
I know I could use an external graphing package, but I’d like to try the inbuilt controls first.
You mention Blend so I assume that you are refering to the WPF/Silverlight chart controls.
The
System.Windows.Controls.DataVisualization.Chartingnamespace is part of the WPF Toolkit. You will have to download this toolkit and reference it from your project.
