Webb14 apr. 2024 · In the simplest example of using mpl_point_clicker, points are obtained by clicking on an image. However, the resulting array when printed is empty, because the code is executed before I can click on the image. import matplotlib.pyplot as plt import matplotlib as mpl mpl.use (‘QT5Agg’) import numpy as np WebbTry to use these indices to access the x and y points by defining: x=numpy.linspace (-4,4,20) y=numpy.linspace (-4,4,20) For example, if you have a min point of (0,1), it would correspond to (x [0], y [1]). I think a similar thing can be done with the mgrid, but I've never used that myself. Tags: Python Plot Matplotlib
