Legend with vertical line in matplotlib
To add a legend with vertical line in matplotlib, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a figure and a set of subplots.
- Plot the vertical line with red color.
- The line can have both a solid linestyle connecting all the vertices, and a marker at each vertex.
- Place a legend on the plot with vertical line.
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt from matplotlib import lines plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True fig, ax = plt.subplots() color = 'red' ax.plot([0, 0], [0, 3], color=color) vertical_line = lines.Line2D([], [], color=color, marker='|', linestyle='None', markersize=10, markeredgewidth=1.5, label='Vertical line') plt.legend(handles=[vertical_line], loc='upper right') plt.show()
