How to remove a legend from a plot?

(The closest I came to this

Answer 1

According to the information from @naitsirhc, I wanted to find the official API documentation. Here are my finding and some sample code.

1. I created a matplotlib.Axes object by seaborn.scatterplot().
2. The ax.get_legend() will return a matplotlib.legned.Legend instance.
3. Finally, you call .remove() function to remove the legend from your plot.

ax = sns.scatterplot(......)
_lg = ax.get_legend()
_lg.remove()

If you check the matplotlib.legned.Legend API document, you won't see the .remove() function.

The reason is that the matplotlib.legned.Legend inherited the matplotlib.artist.Artist. Therefore, when you call ax.get_legend().remove() that basically call matplotlib.artist.Artist.remove().

In the end, you could even simplify the code into two lines.

ax = sns.scatterplot(......)
ax.get_legend().remove()
