How can one create a legend for a line graph in Matplotlib's PyPlot without creating any extra variables? Please consider the graphing script below: if __name__ == '__main__': PyPlot.plot(length,
1 Αυγ 2024 · Add a Legend to a Matplotlib. In this example, a simple quadratic function \ ( y = x^2 \) is plotted against the x-values [1, 2, 3, 4, 5]. A legend labeled “single element” is added to the plot, clarifying the plotted data. Python.
Labelcolor can be set globally using rcParams["legend.labelcolor"] (default: 'None'). If None, use rcParams["text.color"] (default: 'black'). numpoints int, default: rcParams["legend.numpoints"] (default: 1) The number of marker points in the legend when creating a legend entry for a Line2D (line).
First we'll show off how to make a legend for specific lines. import matplotlib.pyplot as plt import numpy as np import matplotlib.collections as mcol from matplotlib.legend_handler import HandlerLineCollection, HandlerTuple from matplotlib.lines import Line2D t1 = np.arange(0.0, 2.0, 0.1) t2 = np.arange(0.0, 2.0, 0.01) fig, ax = plt.subplots
fig, ax = plt. subplots line1, = ax. plot ([1, 2, 3], label = "Line 1", linestyle = '--') line2, = ax. plot ([3, 2, 1], label = "Line 2", linewidth = 4) # Create a legend for the first line. first_legend = ax. legend (handles = [line1], loc = 'upper right') # Add the legend manually to the Axes. ax. add_artist (first_legend) # Create another ...
