How to write annotation outside the drawing in data coords in Matplotlib?

We can use annotate() method to place annotation outside the drawing.

Steps

• Set the figure size and adjust the padding between and around the subplots.

• Create x and y data points using numpy.

• Create a figure and a set of subplots using subplots() method.

• Use scatter() method to plot x and y data points using star marker and copper color map.

• To place annotation outside the drawing, use xy coordinates tuple accordingly.

• 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 x = np.random.rand(100) y = np.random.rand(100) fig, ax = plt.subplots() ax.scatter(x, y, c=y, marker="*", cmap="copper") ax.annotate('Scatter points(outside the drawing)', xy=(0.30, 1.05), xycoords=ax.get_xaxis_transform()) plt.show()
