Hi to all,
I'm a newbie with Teechart and I want to know if a selection functionality exist in Teechart (to be able to select a subset of scatter points in one or multiple series) ??? If no functionality exist is it possible for me to implement that over the active X ? (I'm using the Teechart Active X)
Thanks,
P

How would you like to select the subset? With the mouse? According to their values?

Hey,
In facts, I want to be able to select scatter points with a multi-segment selection tool, and retreive the points which are inside this selection.
The scatter points represents (for me) some kind of pixel information and I want to be able to display the corresponding pixels (in an images display) from the scatter points selection perform on the scatter chart (1 to 1) ... !
Thank you very much,
P

Well, in the same way as zoom selects points you can too. Using the OnMouseDown and OnMouseUp events you can determine the pixel positions of a rectangle and ISeries.CalcXPosValue and ISeries.CalcYPosValue to calculate the value range of these positions.
