How do I change the font size of ticks of matplotlib.pyplot.colorbar.ColorbarBase?
To change the font size of ticks of a colorbar, we can take the following steps−
- Create a random data set of 5☓5 dimension.
- Display the data as an image, i.e., on a 2D regular raster.
- Create a colorbar with a scalar mappable object image.
- Initialize a variable for fontsize to change the tick size of the colorbar.
- Use axis tick_params() method to set the tick size of the colorbar.
- To display the figure, use show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True data = np.random.rand(5, 5) im = plt.imshow(data, interpolation="nearest", cmap="copper") cbar = plt.colorbar(im) tick_font_size = 10 cbar.ax.tick_params(labelsize=tick_font_size) plt.show()
