Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface. There are various plots which can be used in Pyplot are Line Plot, Contour, Histogram, Scatter, 3D Plot, etc.
matplotlib.pyplot.waitforbuttonpress() method
The waitforbuttonpress() method in pyplot module of matplotlib library is used for blocking call to interact with the figure.
Syntax: matplotlib.pyplot.waitforbuttonpress(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.pyplot.waitforbuttonpress() function in matplotlib.pyplot:
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.pyplot.waitforbuttonpress() function Example\n\n""", fontweight ="bold") w = plt.waitforbuttonpress() print("Result after", ite, "click", w) plt.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) plt.clf() ax.axis([-1., 1., -1., 1.]) plt.setp(plt.gca(), autoscale_on = False) tellme("""matplotlib.pyplot.waitforbuttonpress() function Example\n\n""") w = plt.waitforbuttonpress() print("Result after click :", w) plt.show() |
Output:
