4 grpahs ads assembled in 1 graph

I have four graph of "S parameters" in momentum /ads ,
I want assemble them in a single graph , I do not know how to do ?
thank u

Very simple. Add more than one parameter to the curves (button >> Add >>)

thank you very much..
but
but
what I want my graph is to draw four different graph of four-patch antennas in a single graph, not even for a system, how to do that?

It is simple if the designs are in the same project.
Use the dataset drop-down list to select the different designs, then add the s-parameter that you want to plot for that design.

If the designs are in different projects, copy/import the dataset files (*.ds) files into one place.

oh!thank u
