Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.
matplotlib.axes.Axes.invert_xaxis() Function
The Axes.invert_xaxis() function in axes module of matplotlib library is used to invert the x-axis.
Syntax: Axes.invert_xaxis(self)
Parameters: This method does not accepts any parameters.
Returns:This method does not returns any value.
Below examples illustrate the matplotlib.axes.Axes.invert_xaxis() function in matplotlib.axes:
Example 1:
# Implementation of matplotlib function import matplotlib.pyplot as plt import numpy as np X = np.arange(-20, 20, 0.5) Y = np.arange(-20, 20, 0.5) U, V = np.meshgrid(X, Y) fig, ax = plt.subplots() ax.quiver(X, Y, U, V) w = ax.invert_xaxis() ax.set_title('matplotlib.axes.Axes.invert_xaxis() \ Example', fontsize = 14, fontweight ='bold') plt.show() |
Output:
Example 2:
# Implementation of matplotlib function import matplotlib.pyplot as plt import numpy as np x = np.linspace(0, 200, 10) yy = np.transpose([2 * np.sin(x + phi) for phi in x]) fig, ax = plt.subplots() ax.plot(yy) w = ax.invert_xaxis() ax.set_title('matplotlib.axes.Axes.invert_xaxis() \ Example', fontsize = 14, fontweight ='bold') plt.show() |
Output:
