I want to use the histogram to display y(2)  as y(1), but only  Y1 had been displayed correctly ，how to write this script,anyone can help me?

The simplest way to do this is to build the graph interactively, and then under the red triangle, specify to have JMP save the script that will generate the chart as you have interactively built.
