In Plotter, use the SERIES menu/dropdown to scale the data.

As an example for DMTD, I have to multiply the data times 1e-6:

Gave the new data a name, in the top of the dropdown, then in this case, 
enter this formula, in the bottom of the dropdown;


where X1 is the data

WHen it gets thru look at the Column 1 box on the right and you will see 
a check box with your new data.  Uncheck column 1 and Plotter will show 
the new data.  You can now process or save the new data.
