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.set_frame_on() Function
The Axes.set_frame_on() function in axes module of matplotlib library is used to set whether the axes rectangle patch is drawn or not.
Syntax: Axes.set_axis_on(self)
Parameters: This method accept only one parameters.
b: This parameter contains a boolean value and it is used for drawing the axes rectangle patch. Returns:This method does not returns anything.
Note: If True is used, it does not effect any thing.
Below examples illustrate the matplotlib.axes.Axes.set_frame_on() function in matplotlib.axes:
Example 1:
# Implementation of matplotlib function import numpy as np import matplotlib.pyplot as plt x = np.arange( - 5 , 5 , 0.01 ) y1 = - 3 * x * x + 10 * x + 10 y2 = 3 * x * x + x fig, ax = plt.subplots() ax.plot(x, y1, x, y2, color = 'black' ) ax.fill_between(x, y1, y2, where = y2 >y1, facecolor = 'green' , alpha = 0.8 ) ax.fill_between(x, y1, y2, where = y2 < = y1, facecolor = 'black' , alpha = 0.8 ) ax.set_frame_on( False ) ax.set_title( 'matplotlib.axes.Axes.set_frame_on() Example' ) plt.show() |
Output:
Example 2:
# Implementation of matplotlib function import numpy as np import matplotlib.pyplot as plt x = np.arange( 16 ) y = np.sin(x / 3 ) fig, ax = plt.subplots() ax.step(x, y + 2 , label = 'pre (default)' ) ax.plot(x, y + 2 , 'o--' , color = 'black' , alpha = 0.3 ) ax.step(x, y + 1 , where = 'mid' , label = 'mid' ) ax.plot(x, y + 1 , 'o--' , color = 'black' , alpha = 0.3 ) ax.step(x, y, where = 'post' , label = 'post' ) ax.plot(x, y, 'o--' , color = 'black' , alpha = 0.3 ) ax.grid(axis = 'x' , color = '0.95' ) ax.legend(title = 'Parameter where:' ) ax.set_frame_on( False ) ax.set_title( 'matplotlib.axes.Axes.set_frame_on() Example' ) plt.show() |
Output:
