Often you may want to place the legend of a Matplotlib plot outside of the actual plot.

Fortunately this is easy to do using the matplotlib.pyplot.legend() function combined with the **bbox_to_anchor** argument.

This tutorial shows several examples of how to use this function in practice.

**Example 1: Place Legend in Top Right Corner**

The following code shows how to place the legend in the top right corner outside of a Matplotlib plot:

import matplotlib.pyplot as plt #create plot plt.subplot(211) plt.plot([2, 4, 6], label="First Data") plt.plot([6, 4, 2], label="Second Data") #place legend in top right corner plt.legend(bbox_to_anchor=(1,1), loc="upper left") #show plot plt.show()

Note that theÂ **locÂ **argument tells Matplotlib to place the **upper leftÂ **corner of the legend line at the (x,y) coordinates of (1,1) in the plot.

**Example 2: Place Legend in Bottom Right Corner**

The following code shows how to place the legend in the bottom right corner outside of a Matplotlib plot:

import matplotlib.pyplot as plt #create plot plt.subplot(211) plt.plot([2, 4, 6], label="First Data") plt.plot([6, 4, 2], label="Second Data") #place legend in top right corner plt.legend(bbox_to_anchor=(1,0), loc="lower left") #show plot plt.show()

Note that theÂ **locÂ **argument tells Matplotlib to place the **lower left **corner of the legend line at the (x,y) coordinates of (1,0) in the plot.

**Example 3: Place Legend Above Plot**

The following code shows how to place the legend above the Matplotlib plot:

import matplotlib.pyplot as plt #create plot plt.subplot(211) plt.plot([2, 4, 6], label="First Data") plt.plot([6, 4, 2], label="Second Data") #place legend above plot plt.legend(bbox_to_anchor=(0, 1, 1, 0), loc="lower left", mode="expand", ncol=2) #show plot plt.show()

Note that theÂ **mode **argument tells Matplotlib to expand the legend to the length of the plot and the **ncol **argument tells Matplotlib to place the legend labels in 2 columns.

We could also leave out the **modeÂ **andÂ **ncolÂ **arguments if we simply want to place the legend in the top left corner above the plot:
