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?
