With ArcMap 10 I have enjoyed automating individual maps of tracked animals using Python (facilities available under arcpy.mapping).  
In these plots I wish to also display a graph depicting the chronology of the animal's behavior  (example plot attached).  
However, I have found no Python handle to update the graph as I update the animal information 
(Note the discordance between the timeframe of the tracking and chronology data in the attached map).
Have I missed a hidden gem that would allow me to do this?
