python - Matplotlib global legend for lots of subplots -

i have problem figuring out how force matplotlib add legend want.

the figures have this:

i generate 2 paged plot following script:

n = 1 trn = true in diff.keys():     plt.subplot(8, 4, n)     plt.xlim([0, rounds + 1])     plt.locator_params(axis='y', nbins=5)     if peptide_kd[i] == 1e-2:         plt.plot(x_cord, [x[0] x in diff[i]], 'ro--', label='asd')         plt.plot(x_cord, [x[1] x in diff[i]], 'rv--', label='bsd')     else:         plt.plot(x_cord, [x[0] x in diff[i]], 'bo--', label='asd')         plt.plot(x_cord, [x[1] x in diff[i]], 'bv--', label='csd')     plt.title(i)     n += 1     if n == 33 , trn:         n = 1         trn = false         plt.suptitle('ligand energies')         plt.locator_params(axis='y', nbins=5)         plt.subplots_adjust(hspace=0.35)         plt.show()  plt.legend(bbox_to_anchor=(-0.05, 1), loc=1) plt.locator_params(axis='y', nbins=5) plt.subplots_adjust(hspace=0.35) plt.show() 

however place legend @ left side of first subplot, or right side of last subplot in first line.

i can if line == 0 bla bla, problem can see in plots attached example last plot contains blue data, hence blue legend show. place full legend (red , blue) same place. dont know blue , red plot placed beforehand.

is possible?

try using figure legend let create legend any of lines plotted in figure , position relative figure.
