Remove the legend border in Matplotlib
• Last Updated : 17 Dec, 2020

In this article, we will learn how to Remove the legend border in Matplotlib. Let’s discuss some concepts :

• A legend is an area describing the elements of the graph. In the matplotlib library, there’s a function called legend() which is used to Place a legend on the axes.

Approach:

1. Import Library (Matplotlib)
2. Import / create data.
3. Plot a chart.
5. Remove legend border.

Example: Here is an example with legends.

## Python3

 `# impoting packages``import` `numpy as np``import` `matplotlib.pyplot as plt`` ` `# create data``x ``=` `np.linspace(``1``, ``10``, ``1000``)``y1 ``=` `np.sin(x)``y2 ``=` `np.cos(x)`` ` `# plot graph``plt.plot(x, y1)``plt.plot(x, y2)`` ` `# add legend``plt.legend([``'Sine wave'``, ``'Cos wave'``])``plt.show()`

Output: Method 1: (Using frameon = False)

## Python3

 `# impoting packages``import` `numpy as np``import` `matplotlib.pyplot as plt`` ` `# create data``x ``=` `np.linspace(``1``, ``10``, ``1000``)``y1 ``=` `np.sin(x)``y2 ``=` `np.cos(x)`` ` `# plot graph``plt.plot(x, y1)``plt.plot(x, y2)`` ` `# add legend and remove frame``plt.legend([``'Sine wave'``, ``'Cos wave'``], frameon``=``False``)``plt.show()`

Output : Method 2: (Using legend.get_frame().set_alpha(0))

## Python3

 `# impoting packages``import` `numpy as np``import` `matplotlib.pyplot as plt`` ` `# create data``x ``=` `np.linspace(``1``, ``10``, ``1000``)``y1 ``=` `np.sin(x)``y2 ``=` `np.cos(x)`` ` `# plot graph``plt.plot(x, y1)``plt.plot(x, y2)`` ` `# add legend``leg ``=` `plt.legend([``'Sine wave'``, ``'Cos wave'``])`` ` `# set opacity equal to zero i.e; transparent``leg.get_frame().set_alpha(``0``)``plt.show()`
