Been using pyqtgraph for some time. Very happy and impressed. An important question I have had for some time is:
Is it possible to get access the data held in the graphic objects? For example.. I can create a line item. I can plot and I can rotate it and translate it with pyqtgraph methods. If it translate it how do I know where the new end points are? The plotting engine must know otherwise it couldn't work. I understand it is a fast plotting library. But surely the underlying data would be of extreme value for analysis? I have just used the isolineItem to find the contour of a laser spot. The visual feedback is helpful. Though I don't know how to get the array of data to proceed with things like finding the center. I seem to be missing something here....?
