ADS parameter sweep trace color

When I perform a parameter sweep in ADS, the traces are always the same color. I cant even lick on an individual trace. Is there a way to make the traces resulting from different parameters easier to distinguish?

Double Click the curve, "Trace Options"->>Linear->>Line Color ( tick the box)

Thank you, it works.

Another question, if I manually change a parameter and simulate again, is it possible to have the previous traces to be overlaid with the newly simulated trace?

Have a look at the "History" menu in the ADS data display.

It works, but the history trace is a very thick blue line. I could not find where to edit the trace color+thickness
