[Zope] Generating Graphs on the Fly

[Laurie Nason]

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
