Extract Scatter Plot Decile Line Values

Hi All,

I need to apply the same value decile lines from one visualization to the next. 



Scatter Best Decile = 123.00

Scatter Median = 567.00


This chart now needs the same values from above (does not matter if the data within this chart changes)

Bar Best Decile = 123.00

Bar Median = 567.00


Basically, I need to store the decile line values from the Scatter chart so that I can use those same values elsewhere.

I was hoping I could assign these values to a document property through an Iron Python script but I have not had any luck yet.

Please help!
