How to show separate legend for each subplot

Community matplotlib-users

Hi,

I am wondering is there a way one could show a separate legend for each subplot in a figure? I would really really appreciate any ideas on this.

Thanks,

Omer

Omer,

Give this a shot:
# code --------->
import matplotlib.pyplot as pl
fig = pl.figure()
ax1 = fig.add_subplot(1,2,1)
ax2 = fig.add_subplot(1,2,2)

ax1.plot([1,2], [3,4], 'ko', label='First Axes')
ax2.plot([2,3], [4,5[, 'bs', label='Second Axes')

ax1.legend()
ax2.legend()
# <------------- code

There's also an example in the Examples section of the MPL website:
http://matplotlib.sourceforge.net/examples/pylab_examples/legend_demo3.html

Hope that helps,

Hi Paul,

Thanks for your prompt response. It did help :slight_smile:

But it seems that axis don’t seems to accept title, xlable and ylable values any more. Any ideas on that?

Cheers

If you're trying to use the functions plt.title() and plt.xlabel(),
they only work on the current axes object (basically, the most
recently created one). You'll want to try to use methods on the axes
themselves:

ax1.set_title('ax1 title')
ax1.set_xlabel('xlabel')

ax2.set_title('ax2 title')
ax2.set_xlabel('xlabel')
