• JSL: Creating formula using a variable column name

  Hi,
  
  I want to do an actually simple thing (at least I thought so), namely to create a new column using JSL with a formula that contains a variable column name. I already tried several combinations of the commands "column, as column, name, as name, eval, parse .." and I searched the forum, but everything I tried results in an error that the formula could not be evaluated.
  
  An example what I want to do...

• Multiple means comparision for non-parametric data?

  I am analyzing some data that is so strongly left-skewed that it has to be analyzed nonparametrically.

• Plotting time series data in JMP

  I find the bubble plot time variable capability a wonderful tool to demonstrate to managers how product sales change over time. I now have a need for a stacked bar chart where the x variables are static, character variables, say apples, oranges, grapes. The bar and stack heights would change over time, oh say based on quantity sold by color. And of course I would need to export the graph to pow...
