Let's take a look at the examples and effects below.

#-*-Coding: UTF-8-*-from matplotlib. widgets import MultiCursorfrom pylab import figure, show, treaty = np. arange (0.0, 2.0, 0.01) s1 = np. sin (2 * np. pi * t) s2 = np. sin (4 * np. pi * t) fig = figure () ax1 = fig. add_subplot (211) ax1.plot (t, s1) ax2 = fig. add_subplot (212, sharex = ax1) ax2.plot (t, s2) multi = MultiCursor (fig. canvas, (ax1, ax2), color = 'R', lw = 1) show ()

The following figure shows the graphic effect. as the cursor moves, a vertical line will be drawn between the two images.

This function is sometimes useful.

I hope this article will help you with Python programming.
