Free or lasso select in TeeChart

[XRD_Tom]

Helllo,

I am looking for a way to select data points in a 3D Chart by drawing a free line (or lasso) around them.
Like shown in the picture:

Is that possible at all and is there maybe some example code available?

Best regards,

Tom

Hello Tom,

There's no built-in method for this, but it should be possible to calculate the drawing polygon and loop the points to check which ones are inside it.
If you still find problems with it, please send us a simple example project we can run as-is to reproduce the situation here.
