I am trying to overlay datapoints from a column and a function line in Graph Builder. However, whenever I place the variables on the same axis and overlay them, I end up with either:
- both the datapoints and the function drawn as points, or
- both drawn as lines.
What I want is simple:
- the column data should appear as points, and
- the function should appear as a line,
overlaid in the same graph.
Below is a JSL script that generates a small sample table with two random columns and a function column. Here, Column 1 and Column 2 are random values, and the function column is a polynomial function of Column 1. When I use Graph Builder, JMP places them on separate graphs unless I overlay them, and once I overlay, Graph Builder forces all Y variables to share the same element type.
It appears that Graph Builder cannot mix points and lines when multiple Y variables share the same axis in an overlay.
Attached is the plot that I currently see, showing how Graph Builder places the function and datapoints on separate axes or forces them into the same element type when overlaid. Here I am using the version JMP 18.
Does anyone know whether there is a way to overlay a function line and datapoints on the same graph in Graph Builder while keeping different element types? Or is Graph Builder limited in this case?
