if your generated url is /a/c/f/*graf_comp_gior*?var1=a&var2=b I assure you
that those will be passed.
as for the graphing library, I highly suggest to switch to a javascript
based solution rather than a python one for any web site.

You can also use this:

If I understand correctly, once you provide some static libraries, you can
serve your plots as plain html, or even json, in your views.

In a controller (the import is done in a model) :

many many thanks Alan, youre answer is 100% percent correct and works
perfectly. Really appreciate you taking the time

The code I posted will create a temp file, them move it to uploads (not
static) using db.table.file.store(...) The store function will create a new
unique and secure filename in upoads. If you have no future plans to add
access control to these files, than you can put them in static. In that

Makes perfect sense.
When you use matplotlib you can do:
You can store the image in temp file:

You need two functions. One returns the image. One returns the view
that embeds the image.

thank you
this is working example

os.environ['MPLCONFIGDIR'] = tempfile.mkdtemp()
import cStringIO
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
import numpy as np
def draw():

You can send the image directly to the view, for an example see:

i've installed the latest verson of matplotlib (from source, also libpng
and freetype)
now matplotlib is working
but using MATLAB a lot, i have one question: is it possible to
usematplotlib.pyplot instead of matplotlib api (matplotlib.figure) and not
saving the file (sendign directly to view)?
probably problem with mod_wsgi
any solutions?
andrej
the line
#os.environ['MPLCONfigureDIR'] = tempfile.mkdtemp()
should be
os.environ['MPLCONFIGDIR'] = tempfile.mkdtemp()
but now there is this error:

Next step is to upgrade the HTML code because this just looks like text.

The view need a controller to return a dict variable at least one to be
executed I think...
So maybe your controller has noting to do so you just have created a view
with the code that you want to be executed (the code that you showed us)...
Try returning a empty var from your controller if you h

Have you shown us your entire index() function? If so, your view file isn't
getting called at all because your index function is not returning a

returns, which is probably None if the last line is a call to plt.savefig().

Besides this issue; is using a temporarily file a mature solution or is

To follow up, if I were to go about this in a brute force manner, by
