Hi,
I craeted a chart with "LineSeriesDefinition" and the ItemSource is ObservableCollection<ObservableCollection<T>>
When <T> has the next properties:
"Tab (string)", "Date (DateTime)", "Count (int)"
The issue is when I get the invocation of ItemToolTipEventHandler for the last entry on the line it's with the bind item of thr previous one, it is append only for the last one!!!
