I have a SeriesMapping bound to IList<Tuple<string,int>>. The XAxis is bound to the string as a XCategory and the yaxis to the int.
Below is my xaml and my viewmodel.
The data is presented just as i want to but with a strange thing happening when i bound to a large list. It seems that the xcategory breaks down once the collection is past 200 items (in code below the for loop where i<190 - change that to say 210 and hell breaks loose). The xcategory gets messed up to numbers and not categorized anymore. See the 2 screenshots.
