The view is not executed. Adding return dict() doesn't have effect. Even
this diccccct() does not lead to an error.
{{extend 'layout.html'}}
{{if 'message' in globals():}}
<p> Outfile from Matplotlib
<img src="{{=URL('static','mp1.png')}}"/>
</p>
return diccccct()

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 dictionary. Instead, web2py is simply returning whatever
your function returns, which is probably None if the last line is a
call to plt.savefig(). Add return dict() to the end of your index
function, and see if it works. Views are only called if the controller
function returns a dictionary.

The following views/default/index only gives an empty page with
"None" in the top left corner.

{{extend 'layout.html'}}
{{if 'message' in globals():}}
<h1>{{=message}}</h1>

Looking closer an output window appears and the console gives
errors on the sequence of calling matplotlib.backends:
I'll check first.

But does
plt.savefig(os.path.join(request.folder,'static','mp1.png'),format='png')
result in a file being saved in
c:\web2py\applications\your_app\static\?

Anthony,
plt.savefig('c:\web2py\outputfile.png',format='png')
does me give an accessable png-file

Have you confirmed that the file is actually getting saved
in the expected location? Are you able to run the
matplotlib code and save the file outside of web2py?

Only adding the .png extention is not sufficient.
outputfile =
os.path.join(request.folder,'static','mp1.png')
plt.savefig(outputfile,format='png')
<p> Outfile from Matplotlib

</p>
Besides this issue; is using a temporarily file a
mature solution or is streaming preferrable?

Should be URL('static','mp1.png').
