Get legend as a separate picture in Matplotlib

Question

I\'m developing a Web application and want to display a figure and its legend in different locations on the page. Which means I need to save the legend as a separate png fil

Answer 1

I've found that the easiest way is just to create your legend and then just turn off the axis with plt.gca().set_axis_off():

# Create a color palette
palette = dict(zip(['one', 'two'], ['b', 'g']))
# Create legend handles manually
handles = [mpl.patches.Patch(color=palette[x], label=x) for x in palette.keys()]
# Create legend
plt.legend(handles=handles)
# Get current axes object and turn off axis
plt.gca().set_axis_off()
plt.show()
