Sorry, I wasn't clear. I am using Graph Builder. Below is the example code. I was hoping these edits could be handled within the GraphBuilder() function itself, but can't seem to find correct syntax in Help manuals.
obj = Graph Builder(
Variables( X( :WW), Y(:WW), Y( :YIELD, Position(1), Side("Right" )) ),
Elements(
Bar(X, Y( 1), , Bar Style("Side by side"), Summary Statistic("N") ),
Line (X, Y( 2), Summary Statistic("Mean") ),
Title(prog),
//show legend(1),
),
);
