    Sherrill,

    In an overlay plot you can simply "Normalize X" on the scaling tab under plot options.  This might work well for UPLC vs HPLC comparisons.

    Alternatively, if you needed a little more control over the scaling you could use Derived Channels in the Method Set.  Under the Filter/Offset Channel, you can define parameters for "RT Offset / Scaling".  This allows you to take the original channel and define start/stop time and convert them to a derived channel start/stop time.
