Crash when legend box is inside plot area

[thubble]

Hi,

I'm using build 3597. When the legend box is inside the plot area (cfx:Chart.TargetPanel="Inside"), and I use a GridSplitter to shrink the chart down to nothing, I get the following error:

Width and Height must be non-negative.

I've attached an app that reproduces this issue. Just run the app, then use the GridSplitter (it's right above the chart) and drag it all the way to the bottom of the window, as far as it will go. This should produce the error.

I've also noticed that if the chart has hardcoded SeriesAttributes, and the legend box is inside the plot area, the legend box won't show up. In the test app, uncomment the 2 SeriesAttributes lines in Window2.xaml, then in Window2.xaml.vb:ReinitializeData(), get rid of the 2 lines that set the chart's ItemSource.

Thanks.

These 2 issues have been fixed on build 3609
