Hello,
I use a QwtPlotCurve with some points assign with setRawSamples. I want to get the X or Y cooridnates of a point in the curve using Y or X associated coordinate, but this point is not always a point that i use to create the curve.
Exemple:
i have two point to create the curve
pointA(0,0) and pointB(2,2) and i want to find the coordinate of the point in the curve coresponding to x = 1. in this case the point has 1,1 for coordinates.
is this is possible and how to do.
Thanks for your help.
