no more inline matplotlib plots in sage notebook
I can't get any matplotplib/pylab plots inline in a notebook. Plots now are created as pdf files that open in another window.
For example, the code below used to create the plot in a new box after the instruction plt.savefig('.')
import numpy as np import pylab as plt x = np.arange(-2 * np.pi, 2 * np.pi,0.1) plt.figure(1) plt.clf() plt.plot(x, np.sin(x), label='sin(x)') plt.savefig('.')
now it returns a link '.pdf' to a pdf file.
returns the following traceback:
Traceback (most recent call last): File "", line 1, in <module> File "/private/var/folders/k7/k7XHz3-82RazCk+kNOj55U+++TM/-Tmp-/tmpjD4zHK/___code___.py", line 14, in <module> exec compile(u"plt.savefig('a.png')" + '\n', '', 'single') File "", line 1, in <module> File "/tmp/sage-mac-app/local/lib/python2.6/site-packages/matplotlib/pyplot.py", line 363, in savefig return fig.savefig(*args, **kwargs) File "/tmp/sage-mac-app/local/lib/python2.6/site-packages/matplotlib/figure.py", line 1084, in savefig self.canvas.print_figure(*args, **kwargs) File "/tmp/sage-mac-app/local/lib/python2.6/site-packages/matplotlib/backend_bases.py", line 1853, in print_figure print_method = self._get_print_method(format) File "/tmp/sage-mac-app/local/lib/python2.6/site-packages/matplotlib/backend_bases.py", line 1793, in _get_print_method '%s.' % (format, ', '.join(formats))) ValueError: Format "png" is not supported. Supported formats: pdf.
I don't know what settings changes I may have done, and couldn't find any documented help format settings in sage for matplotlib plots. Interestingly I used to experience before the impossibility to export sage generated plots in pdf... It would be nice to have a better control on these settings.
Thank you for any help
