Removing Lineserie points partial - only currently zoomed

[ChristianZ]

Dear all,

I am searching for a solution to remove those points from my line series, which are in the current zoom rectangle.
I know of the LineSeries.Delete(Start, Count) Method - but how do I get my starting and end Index for the points being displayed ?

Thanks in advance for any help

Hello CZ,

Try with FirstValueIndex and LastValueIndex.
If you still find problems with it, please try to arrange a simple example project we can run as-is to reproduce the situation here.
