Each point on the scatter plot is associated with a named object. There is no easy answer to the problem, since I want to create a simple line with two points that can be dragged (one at a time), as in image below: How can I do that without using sliders, but rather dragging the points themselves. Furthermore, when you drag you can observe a change in the x or y value of the Scatter or Label and trigger a python function through that, which in turn generates a new plot. >>> plot (x, y) # plot x and y using default line style and color >>> plot (x, y, 'bo') # plot x and y using blue circle markers >>> plot (y) # plot y Line between two draggable points on a matplotlib pyqt5 canvas. imshow(bild) plt.
