I found the solution looking at txnelson's old posts.
Fit Group(
Rep01=Bivariate(
Y( :Name( "name_01" ) ),
....
),
Rep02=Bivariate(
Y( :Name( "name_02" ) ),
....
),
...
Rep0x=Bivariate(
Y( :Name( "name_0x" ) ),
....
),
<<{Arrange in Rows( 1 )}
);
Report( Rep01 )[ListBox(2)] << save picture(<change this to the path you want to use>\Pic01.jpg");
Report( Rep02 )[ListBox(2)] << save picture(<change this to the path you want to use>\Pic02.jpg");
...
Report( Rep0x )[ListBox(2)] << save picture(<change this to the path you want to use>\Pic0x.jpg);
