Top label for Matplotlib colorbars
To place a top label for colorbars, we can use colorbar's axis to set the title.
Steps
- Create random data using numpy.
- Use imshow() method to represent data into an image, with colormap "PuBuGn" and interpolation= "nearest".
- Create a colorbar for a scalar mappable instance, im
- Set the title on the ax (of colorbar) using set_title() method.
- 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.randn(4, 4)
im = plt.imshow(data, interpolation='nearest', cmap="PuBuGn")
clb = plt.colorbar(im)
clb.ax.set_title('Color Bar Title')
plt.show()Output
