Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The figure module provides the top-level Artist, the Figure, which contains all the plot elements. This module is used to control the default spacing of the subplots and top level container for all plot elements.
matplotlib.figure.Figure.waitforbuttonpress() method
The waitforbuttonpress() method figure module of matplotlib library is used for blocking call to interact with the figure.
Syntax: waitforbuttonpress(self, timeout=-1)
Parameters: This method accept the following parameters that are discussed below:
- timeout: This parameter is the timeout value.
Returns: This method does not returns any value.
Below examples illustrate the matplotlib.figure.Figure.waitforbuttonpress() function in matplotlib.figure:
Example 1:
# Implementation of matplotlib function import numpy as np import matplotlib.pyplot as plt for ite in range(2): x = np.linspace(-2, 6, 100) y = (ite + 1)*x fig = plt.figure() ax = fig.subplots() ax.plot(x, y, '-b') fig.suptitle("""matplotlib.figure.Figure.waitforbuttonpress() function Example\n\n""", fontweight ="bold") w = fig.waitforbuttonpress() print("Result after", ite, "click", w) fig.show() |
Output:
Example 2:
# Implementation of matplotlib function import numpy as np import matplotlib.cm as cm import matplotlib.mlab as mlab import matplotlib.pyplot as plt fig = plt.figure() ax = fig.subplots() def tellme(s): fig.suptitle(s, fontweight ="bold") fig.canvas.draw() renderer = fig.canvas.renderer fig.draw(renderer) fig.clf() ax.axis([-1., 1., -1., 1.]) plt.setp(plt.gca(), autoscale_on = False) tellme("""matplotlib.figure.Figure.waitforbuttonpress() function Example\n\n""") w = fig.waitforbuttonpress() print("Result after click :", w) fig.show() |
Output:
