Hi Timmie
I m using matplotlib and instead of show() just use savefig
('filepath', dpi=dpi)
I make filepath inside static dir, something like /static/myfiles/
tmp0123
This of course requires periodic cleaning by some cron script, e.g.
delete all files older than 4 days. Or try to use python's tmp files
lib.
Thus your controller method could look like
import tempfile
def get_plot():
x=arange(0, 100, 0.1)
y = sin(x)
plot(x, y)
file, filepath = tempfile.mkstemp('.png', dir='static/myfiles/')
#check that - path to static should be more explicit
savefig(tmpfilepath, dpi=72)
response.headers['Content-Type'] = 'application/png' #check that - I
do not remember correct mime type for PNG
response.headers['Content-Length'] = 10**6
return response.stream(filepath)
