See if Graph Builder will do what you want. Select all the columns and drop them on the Y axis. You'll see a point cloud. Here's Big Class using age, height, weight:
then right-click->add->histogram:
then right-click->points->remove, click DONE
click the titles and press delete (Or add a better title)
then you can use the red triangle to copy the script:
Graph Builder(
Size( 534, 418 ),
Show Control Panel( 0 ),
Variables( Y( :age ), Y( :height, Position( 1 ) ), Y( :weight, Position( 1 ) ) ),
Elements( Histogram( Y( 1 ), Y( 2 ), Y( 3 ), Legend( 3 ) ) ),
SendToReport(
Dispatch( {}, "graph title", TextEditBox, {Set Text( "Students" )} ),
Dispatch( {}, "X title", TextEditBox, {Set Wrap( 2 )} ),
Dispatch( {}, "Y title", TextEditBox, {Set Text( "" )} ),
