I am trying to implement a simple mouse click event in matplotlib. I wish to plot a figure then use the mouse to select the lower and upper limits for integration. So far I am able to print the coordinates to screen but not store them for later use in the program. I would also like to exit the connection to the figure after the second mouse click. Below is the code which currently plots and then prints the coordinates. My Question(s): How can I store coordinates from the figure to list? i.e. click = [xpos, ypos] Is it possible to get two sets of x coordinates in order to do a simple integration over that section of line? import numpy as np import matplotlib.pyplot as plt x = np.arange(-10,10) y = x**2 fig = plt.figure() ax = fig.add_subplot(111) ax.plot(x,y) def onclick(event): global ix, iy ix, iy = event.xdata, event.ydata print 'x = %d, y = %d'%( ix, iy) global coords coords = [ix, iy] return coords for i in xrange(0,1): cid = fig.canvas.mpl_connect('button_press_event', onclick) plt.show() Continue reading...
