Hi @ManuelWilbring ,
I'm not entirely sure how to do this, as it's not something that I would normally work with, however what I think you're wanting to do is something similar to what is shown in the JMP Clinical online help, here. If so, and you don't have Clinical and using Pro, then after you do your Proportional Hazards Fit, in your Hazards Ratios for Unit or for a categorical variable, I would right click that table in the report and select make into data table.
The below is an example from the JMP sample data, VA Lung Cancer.jmp file.
Right clicking the Hazard Ratios for Cell Type and selecting make into data table gives you the following table:
And then you can use Graph Builder to create your Hazards Ratio plot:
At least conceptually this is similar to the JMP Clinic help page from above.
Is this what you're looking to do? It appears as if JMP Clinical has this feature built into its functionality. Can you get JMP Clinical? It might be worth looking into it if you will be doing a lot of analyses like this.
Hope this helps!,
DS
