I posted the code in a subsequent article "A Better AE + CM Graph".
In my opinion, this graph is clearly superior to the previous version. It follows the principles of effective graphics, were related information is presented together. I would like to reduce clutter, and highlight the appropriate items.
After the presentation, and also recently at the Minnesota SAS users' group meeting, users stopped by to discuss these graphs, and ways to further improve the graph to help the PI clearly view each AE event and associate it with the CM prescriptions exactly.
