I need to have the graphic on a web page... as soon as a user hit summit...
If you need to plot a chart, you can matplotlib, if that is not
so easy to implement, you can try using django google charts packages:
http://pypi.python.org/pypi/django-googlecharts/1.0-alpha-1
http://pypi.python.org/pypi/django-google-charts/0.1.1

As a quick hack, you could generate a postscript file using
savefig(). Then, you could print that from the commandline to a
local printer--If they don't need a physical printout, I would
generate a pdf file and serve it to them and let them print it. If
I figure out how to print directly using the printer dialog, I'll
let you know...

it is an intranet, and I don't have any restrictions
using JavaScript... abd I am using matplotlib... I thing it is
the only way to save a file and put it on the web page...

What are you using for your plotting package? Matplotlib?
I think that this will show the plot (on the server
machine)--the easiest thing I can think of for now (assuming
that you are using matplotlib) is to generate a pdf and send
them the file. I haven't tried printing directly--is this
intranet, or external facing? Do you have any restrictions
on using javascript?

a user to print one
I did this in python, but throws an error in django when
I tried to run it... I have seen some examples of saving
an image, but I would like to avoid that since I don't
want to open and close a file...
let me know if you have any idea....
thanks
Python program:
def drawPlot(arrayGene1, arrayGene2):
message = ''
(m,b) = polyfit(arrayGene1,arrayGene2,1)
yp = polyval([m,b],arrayGene1)
xlable('Gene 1')
ylable('Gene 2')
title('Correlation Graph')
plot(arrayGene1, yp)
scatter(arrayGene1,arrayGene2,marker='>')
show()
return(message)

Do you need to display a graph, or allow the user to

The information comes from a database, which I
got it with a problem. However, I need to show a
graph as well.
Please let me know any suggestions...
thanks and have great day.
