Thank you Massimo. Everything is working now. I misunderstood something.
Michele, thanks for the tip!

Maybe you want "embed" in html which is much cooler it requires only one
single request/response:
def index():
form = SQLFORM.factory(Field('x')).process()
img64 = None
if form.accepted:
img = myplotfunction(form.vars.x)
img64 = embed64(data=img,extension='image/png') # <- !
Not sure I understand. You have every piece you need.
def index():
form = SQLFORM.factory(Field('x')).process()
return locals()
and in index.html()
{{=form}}
{{if form.accepted:}}
{{pass}}

I have all this working the same way as Massimo suggested with matplotlib, no
problems.
But, I can't for the life of me figure out how to pass a variable into the
controller plot function from the view. This would be so I can, for example,
ask the user to choose a variable through a form and t
You do not return the image that way. You need two actions, one only
returns plot() (the binary data) and another would be a regular action
which display a link to the other action.
def myimage(): return plot()
def Testing(): return dict() # in view ...

I did some experimenting the problem is putting the image into the return
dict() or into any variable.
I got no clue how to fix it or why that is the problem.

I tried that but it doesn't show an image it puts the img tag in the html
code and fills the src="" with the pinary stuff but no image is displayed

Hi,
I like to add Graphs with matplotlib directly into my sites. I used a
web2py slice to get an image into a variable:
from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
from matplotlib.figure import Figure
import cStringIO
def plot(title='title',xlab='x',ylab='y',mode='
