Hi, I do not have a great knowledge of this module, I'm trying to draw a
cad file with pyqtgraph, once I try to take the position of the mouse,
to extract the value of plot.
but I found a substantial diffrence between the coordinates drawn and those
taken with the mouse.
I attach the code I have generated.
I hope for help
