How to show mouse release event coordinates with Matplotlib?

To show mouse release event coordinates with matplotlib, we can take the following steps−

• Set the figure size and adjust the padding between and around the subplots.
• Create a figure and a set of subplots.
• Plot a line in the range of 10.
• Bind the function *onclick* to the event *button_release_event*.
• Print event and its x and y data.
• To display the figure, use show() method.

Example

from matplotlib import pyplot as plt
plt.rcParams['backend'] = 'TkAgg'
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
def onclick(event):
print(event.button, event.xdata, event.ydata)
fig, ax = plt.subplots()
ax.plot(range(10))
fig.canvas.mpl_connect('button_release_event', onclick)
plt.show()

Output
