Using Python Script to change Pie Chart Symbology

I am trying to change the symbology for Pie chart in ArcGIS.

I have a feature class which is joined to a table and I will like to symbolized as a pie chart. I will be symbolizing it a lot thus I am looking for an automation ways to do this task. Map Layer does not work in this case.

I am very new to Python Scripting and I am wondering if there is there a way to add symbology using Python Script?
