Sort descriptors not sorting (correctly)?

[Adam Petaccia]

I have a RadChart which receives data in a fairly ordered fashion (the data points are not guarenteed to be ordered, but almost always are). However, charts seem to have their data ordered bizarrely (I'm basically trying to sort by the XCategory). If I apply an ascending sort descriptor to the chart, there is no effect; descending does indeed "go in reverse" but the data still isn't actually sorted. For horizontal bar charts this results in shuffled data, but for line charts, it results in tens of lines darting horizontally back and forth. The sort descriptors are added to both RadChart.SortDescriptors and SeriesMapping.SortDescriptors. A grouping is in effect, but not by XCategory.

Is this a common pitfall? Is something obvious missing?

Hello Adam Petaccia,

Can you send us a sample app/project demonstrating the issue so that our dev team can take a look at what's going on? You can open-up a bug report in order to attach the file.

Thanks in advance!

All the best,
Vladimir Milev
the Telerik team

Embarrassingly, this was a bug in the backend code causing some points to be dropped and later grouped incorrectly.
