i'm trying use lop populate subplot can't so. here summary of code: edit 1:
for idx in range(8): img = f[img_set[ind[idx]][0]] patch = img[:,col1+1:col2, row1+1:row2] if idx < 3: axarr[0,idx] = plt.imshow(patch) elif idx <6: axarr[1,idx-3] = plt.imshow(patch) else: axarr[2,idx-6] = plt.imshow(patch) path_ = 'plots/test' + str(k) + '.pdf' fig.savefig(path_) it plots image on 3rd row , 3rd column rest of plot blank. how can change that?
you forgot create sub plots. can use add_subplot() (http://matplotlib.org/api/figure_api.html#matplotlib.figure.figure.add_subplot). example,
import matplotlib.pyplot plt fig = plt.figure() idx in xrange(9): ax = fig.add_subplot(3, 3, idx+1) # line adds sub-axes ... ax.imshow(patch) # line creates image using pre-defined sub axes fig.savefig('test.png') in example, like:
import matplotlib.pyplot plt fig = plt.figure() idx in xrange(8): ax = fig.add_subplot(3, 3, idx+1) img = f[img_set[ind[idx]][0]] patch = img[:,col1+1:col2, row1+1:row2] ax.imshow(patch) path_ = 'plots/test' + str(k) + '.pdf' fig.savefig(path_)
