As far as I know, the Graph Builder only has one color scale, which applies to the whole window. It is not possible to have a separate color scale for each graph. Instead, I recommend centering (and perhaps scaling) your data, Grouped by OPERATION.
- Within Graph Builder, right click OPERATION and select GROUP BY.
- Then right click VALUE > Distribution > Center (or standardize, if you want to rescale)
- Use this new Centered VALUE column in your graph.
Does this achieve the graph you want? Of course keeping in mind that it is now plotting a centered/scaled version, not the original raw data. I confirmed it works in JMP 19 using the "Wafer Stacked" sample data file.
By the way, if you wanted to group by WAFER&OPERATION (every graph has its own scale), then see the comments below.
In JMP 17, with a bit of effort:
- Create an "ID" column by selecting "WAFER" and "OPERATION" column headers, right click -> New Formula Column > Character > Concatenate.
- Right click this new ID Column header > New Formula Column > Group By
- Right click your VALUE column > New Formula Column > Then click either Center or Standardize, depending on if you only want to shift the values or also scale them.
- Now, use the new Centered/Standardized data in your plot.
If you are able to upgrade to JMP 19, this becomes much easier as it can be done directly within Graph Builder using Custom Scope (starting around 5:37 in the video). No need for extra columns!
- Within your Graph Builder window, right click your VALUE column -> Distributional -> Center (or standardize).
- Right click the newly created Centered data column and Change Scope to Graph. (You can experiment with other scopes to see what it does).
