ColumnSeries performance with large amount of data
posted

Hello!

I'm trying to make a histogram-style graph, and I'm using ColumnSeries for it. I have about 15k points on the X axis, and with this amount of data the performance of the chart is VERY bad. Chart filling takes about 20 seconds, and zooming is very very slow, so the chart is impossible to use.

ItemsSource is set to ICollectionView, which is used for filtering values.

I tried another types of charts which performed better, but a ColumnSeries is still much more preferable to use (PointSeries are not a histogram-style and with StepAreaSeries it isn't possible to distinguish one point from another when many of them have the same value).

So, what can I do about this? How to make ColumnSeries possible to use with this amount of points? It appears that chart doesn't hide some of the columns like points in the PointSeries, and I think that it might affect performance.

Please help me!
