Reverse the order of a legend

Question

I use the following code to plot the bar graph and need to present a legend in reverse order. How can I do it?

colorsArr = plt.cm.BuPu(np.linspace(0, 0.5, len(C2))) p = numpy.empty(len(C2), dtype=object) plt.figure(figsize=(11, 11))  prevBar = 0 for index in range(len(C2)):     plt.bar(ind, C2[index], width, bottom=prevBar, color=colorsArr[index],             label=C0[index])     prevBar = prevBar + C2[index]  # Positions of the x-axis ticks (center of the bars as bar labels) tick_pos = [i + (width/2) for i in ind]  plt.ylabel('Home Category') plt.title('Affinity - Retail Details(Home category)')  # Set the x ticks with names plt.xticks(tick_pos, C1) plt.yticks(np.arange(0, 70000, 3000)) plt.legend(title="Line", loc='upper left')  # Set a buffer around the edge plt.xlim(-width*2, width*2) plt.show() 

Answer 1

You could call

handles, labels = ax.get_legend_handles_labels() ax.legend(handles[::-1], labels[::-1], title='Line', loc='upper left')

import numpy as np import matplotlib.pyplot as plt np.random.seed(2016)  C0 = list('ABCDEF') C2 = np.random.randint(20000, size=(len(C0), 3)) width = 1.0 C1 = ['foo', 'bar', 'baz'] ind = np.linspace(-width, width, len(C1))   colorsArr = plt.cm.BuPu(np.linspace(0, 0.5, len(C2))) fig = plt.figure(figsize=(11,11)) ax = fig.add_subplot(1, 1, 1)  prevBar = 0 for height, color, label in zip(C2, colorsArr, C0):     h = ax.bar(ind, height, width, bottom=prevBar, color=color, label=label)     prevBar = prevBar + height  plt.ylabel('Home Category') plt.title('Affinity - Retail Details(Home category)')  # positions of the x-axis ticks (center of the bars as bar labels) tick_pos = [i+(width/2.0) for i in ind] # set the x ticks with names plt.xticks(tick_pos, C1) plt.yticks(np.arange(0,70000,3000))  handles, labels = ax.get_legend_handles_labels() ax.legend(handles[::-1], labels[::-1], title='Line', loc='upper left')  plt.show() 

Answer 2

Or you could use the simpler

handles, labels = ax.get_legend_handles_labels() ax.legend(reversed(handles), reversed(labels), title='Line', loc='upper left')
