Changing data types and modelling type while plotting data

[#1]

Hi Team,

It's kind of I'm stuck, I want to change the data type of a column when plotting. 

Explanation : My original data type is "numeric and continuous" but I want to change the data type to "character and nominal" via JSL. It is needed because visual analysis of plots are not very impressive as we can see here

And with data types changed it's acceptable

1) I'm using JSL for plotting using Graph builder, by any chance can I change here in below line beside "user density" while plotting?

To explain more here, though I'm changing the data and modelling types but it seems JMP is not processing the below line arrow marked

Whereas when I'm using this open function code is working as desired and JMP is reading the user density data type and while plotting it's giving desired results.

You can change the data type of column by sending message << Data Type()

and for modeling type use << Set Modeling Type()

Perform these actions after you have the data table open
