Hi, I use matplotlib to create a png file, then display it in a web browser. All works fine. Now I want to zoom the plot. What I can think of is: 1) Get coordinates (x1, y1), (x2, y2) of the image when user makes an area selection on the image; 2) Convert (x1, y1), (x2, y2) to the real values matplotlib was plotting; 3) Request matplotlib to create a new png file using the updated area values. Could anybody please let me know how to accomplish step 2? Many thanks, Tom |
