How to decrease colorbar width in Matplotlib?
To decrease colorbar width in Matplotlib, we can use shrink in colorbar() method.
Steps
- Set the figure size and adjust the padding between and around the subplots.
- Create a random data using numpy.
- Display the data as an image, i.e., on a 2D regular raster, with data.
- Create a colorbar for a ScalarMappable instance, im.
- To display the figure, use show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True data = np.random.rand(5, 5) im = plt.imshow(data, cmap="YlOrBr") plt.colorbar(im, shrink=0.50) plt.show()
