HI @MarcP ,
You might want to try combining a local data filter with the parallel plot.
For example, using the Titanic Passenger.jmp data table from the sample data.
I selected Passenger Class, Survived, Sex, Age, and Fare and dropped them on the X zone.
JMP Graph Builder Drop Zones
I then used passenger class in the color role.
Change from points to parallel plot by clicking on the parallel element.
Dragging the Passenger Class to the last position on the graph produces the following output:
JMP Graph Builder Parallel Plot with Color Role
I then added a local data filter from the red triangle menu option next to the Graph Builder outline.
JMP Local Data Filter
I can then make selections from the local data filter to update the parallel plot.
JMP Graph Builder Parallel Plot with Local Data Filter
Does this get you closer to the type of plot you seek?
cheers,
Stan
