The April '10 release of the Silverlight Toolkit brought stacked series support to the Data Visualization assembly on the Silverlight 4 platform! You can read an overview here and get a detailed description here. Almost simultaneously, the WPF team released WPF 4 as part of .NET 4 and Visual Studio 2010.
So it's time for an updated version of my Silverlight/WPF Data Visualization Development Release. Like the previous version, this one continues to support the four platforms of interest to most .NET developers: Silverlight 3, Silverlight 4, WPF 3.5, and WPF 4. But what about Windows Phone 7, the new fifth platform for .NET developers? Yeah, it's supported, too! :)
Silverlight/WPF Data Visualization Development Release 4
As with previous Data Visualization Development Releases, I've updated the code and binaries to match the most recent Toolkit release. The Silverlight 4 Toolkit shipped most recently, so the code in this Development Release is identical to what just went out with that. Which means people using Data Visualization on Silverlight 3, Windows Phone 7, WPF 3.5, or WPF 4 can also take advantage of the latest round of improvements by updating their applications to use the binaries included with this Development Release (or by compiling the included source code themselves).
Aside: The version of Silverlight used by Windows Phone 7 is conceptually equivalent to Silverlight 3 with a variety of Silverlight 4 enhancements throughout.

Windows Phone 7 Data Visualization Sample
Trying to use the November 2009 version of the Data Visualization assembly on Windows Phone 7 doesn't work because there's a bug in the Phone version of the .NET Framework that causes bogus exceptions. That bug will be fixed in a future drop of Windows Phone 7 developer bits, but for now it was simplest to work around it myself so folks could start playing around with Data Visualization on the phone today. I wrote the sample application below to show that the Silverlight 3 version of Data Visualization now works seamlessly on Windows Phone 7. And while I was at it, I went ahead and customized the default UI a bit (mostly just tweaking colors and backgrounds) so things really fit in with the overall look and feel of the platform:
As part of this, I made some trivial Template customizations for the Chart element and added just a smidge of code to switch Templates when the device orientation changes. This allows the sample application to make better use of the available screen space (note how the Legend moves and changes shape):
