All,
I'd like to ask the community to nudge me in the right direction.
I need to extract R^2 and Slope form the report and display it on the plot itself like so:

I'm going to do this with parsing Display Trees and then looking into Add Graphics Script to the plot itself.
But, since this task seems to me very standard and routine, I have to ask couple of questions before digging into Display Trees:
1. Is there a more straight forward way of doing that? Like Combined Data Table (which gives slope but does not give R^2) for getting number or like Line Of Fit( X, Y, Legend( 5 ), R²( 1 ), Equation( 1 ) ) in graph builder (customer wants to use Bivariate Fit)
2. Maybe somebody already has a snippet of code ready to use for this task?
