I have an application using CollectionIndex feature. I´m using ItemsSource and SeriesMapping radchart properties and I´m adding my lineseries at runtime. All is working great.
Now I want to load data asynchronously to radchart
. My first shot was to use ObservableCollection<ObservableCollection> on my ItemsSource but the chart only shows the data added to collection before my graph shows up. After some time I found RadHierarchicalObservableCollection and the lineseries began to appear but the performance is horrible. I investigated and discovered that each call to AddRange generated a Rebind.
I´m trying to add 6 series with 10000 points each.
There are another way to do it?
Thank you very mutch.
