Hello,
I'm playing with picture generating code like this:
#+begin_src python :results file :session :var
matplot_lib_filename="figure2.png" :exports both
import matplotlib.pyplot as plt
data = [14.0, 7.6, 11.2, 12.8, 12.5, 9.9, 14.9, 9.4, 16.9, 10.2,
14.9, 18.1, 7.3, 9.8, 10.9, 12.2, 9.9, 2.9, 2.8, 15.4, 15.7, 9.7,
13.1, 13.2, 12.3, 11.7, 16.0, 12.4, 17.9, 12.2, 16.2, 18.7, 8.9,
11.9, 12.1, 14.6, 12.1, 4.7, 3.9, 16.9, 16.8, 11.3, 14.4, 15.7,
14.0, 13.6, 18.0, 13.6, 19.9, 13.7, 17.0, 20.5, 9.9, 12.5, 13.2,
16.1, 13.5, 6.3, 6.4, 17.6, 19.1, 12.8, 15.5, 16.3, 15.2, 14.6,
19.1, 14.4, 21.4, 15.1, 19.6, 21.7, 11.3, 15.0, 14.3, 16.8, 14.0,
6.8, 8.2, 19.9, 20.4, 14.6, 16.4, 18.7, 16.8, 15.8, 20.4, 15.8,
22.4, 16.2, 20.3, 23.4, 12.1, 15.5, 15.4, 18.4, 15.7, 10.2, 8.9,
21.0]
plt.clf()
plt.hist(data, bins=10, edgecolor='black')
plt.grid(True)
plt.axis([0, 25, 0, 25])
plt.savefig(matplot_lib_filename)
matplot_lib_filename
#+end_src
and it works great when I evaluate it: it creates a link to the
picture,
and when I hit Enter on the link, the picture is displayed in the
buffer.
The problem is when I modify the code block and run it again, if I
hit
Enter on the resulting link, I see the old picture. The new one is
there
(if I open it, it is modified), but somehow the old picture is
cached.
Is there a way to disable this cache?
Thanks,
Alan
