Hi,
I think you may just need to convert the pixel ("scene") coordinates to the
plot ("view") coordinates. There's a function to do this in ViewBox:
https://pyqtgraph.readthedocs.io/en/latest/graphicsItems/viewbox.html#pyqtgraph.ViewBox.mapSceneToView
Typically, it might be used something like:
mousePoint = self.plot.getViewBox().mapSceneToView(pos)
where pos is a tuple of the scene coordinates, eg. the (110, 620) you are
receiving from the event.
