In ADS, what is the easiest way to save a dataset for easy viewing in a data window later? Ex: Run harmonic balance in a schematic and view the data via a graph in the data display. Change a parameter and rerun the simulation. View the new data on the same graph in the same window while keeping the entire previous dataset saved (not necessarily visible). I know there is history, but I would like to be able to recall a specific dataset that I have saved for later. Thanks.
