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...

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 print one?

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.
