I'm trying to compare data from a 991.2 and a C7 Corvette.  I've exported the lap from the PDR file as a PDS and can open it in a workbook with the 991.2 data.  However, the channels have different names in many cases.  For instance, on the 991.2 it's [yaw can] and on the C7 is't [Yaw Rate].  Is there a way to map these two to a single channel?

I tried using the ifExists function like ifExists([Yaw Rate], [yaw can]) but that won't work because on the C7 that is an undefined channel.

Thanks.

Hi,
        You can achieve this by going to Channel Properties menu.. From there select each of the channels and set colours and set the Autoscale to OFF. Then set the min/max of each channel to be the same so they will overlay.. Then just below the min/max selection is Y axis % enabled.  Enable this (Yes)  Do this for both channels.  Now go to your worksheet with these channels selected.  You need to set the worksheet to Overlaid ("T" Key to toggle)   In Overlaid mode click on each channel and you will see the Channel scale will pop up on the lift side.. you can grab either end of this scale with the mouse and drag the min or max values to where you like. You can also grab the middle and move the whole scale. If you make these scale sizes and position on the graph the same for both channels then you can see them overlaid.  As this works only in Overlaid setting, you will need to set the y axis % enabled on all the channels that you want on this worksheet so you can drag all channels to where you wish to view them. 
Cheers.

Thanks littleozfella, that's how I'm doing it now but the down side is that you also need to make duplicates of all the math channels that use those channels and reconfigure all of your displays with these overlays.  I was hoping there was an easier way.  I appreciate the help yet again.

How about creat math-channel like below,
ifExist( [Yaw Rate],0)+ifExist( [yaw can] ,0)

Brilliant!  That seems to work.  I just have to make sure that I don't set to the data rate to "same as channel".  Thank you very much.
