Thanks David - I got this to work - I passed in my python dictionary into the image as a string and then did an eval() on it to get it back into dictionary form. Worked like a charm! Still a few bugs to sort out though!

The values will all be string values, but you can perform the necessary conversions from meth_1. Hope this helps, David Burton 16/05/2002 21:22:58, "Laurie Nason" <lnason@bcm.tmc.edu> wrote:
Hi all,
Here's the problem,
I want to use a python site-package called pychart to generate graphs for my laboratory.
If I provide all the parameters required internally an the External Method, I can get the graph to be produced. To generate the graph I have a DTML Method (meth_1) which calls my_graph_external_method. To use my graph all I have to do is: <img src="meth_1">.
But, what I want to do is to be able to pass in parameters to the external method, i.e. graph type, data, labels etc. so that the users can customize their graphs. However I can't pass in any parameters to meth_1.
I don't really want to make the process 2 step by creating the file with one method and then reading it with another.
Anyone any ideas?
Laurie
