Does anyone know or have any sample code that would help on such feature? I have a PolyLineROI that defines a road path and a plot that defines the vertical level bellow or above it. I would like a ruler that can snap to the plot points (the plot is defined as PLotWidget.plot(x=Xlist, y=Ylist, symbol="o") so snap to the o's i mean) and the ROI's segments, displaying the text between them,
I thought about a ROI with a single segment that can be dragged all around but I have no idea how to make that snapping works.But maybe I'm reinventing the wheel and this is already implemented with another name or maybe someone has already some sample for this that you wouldn't mind to share?
