Changing plot date range for multiple graphs simultaneously

Hello,

I have a display book with many different plots of various monitored conditions around the plant.

Occasionally I wish to look back at events that have occurred in the past, using this display book. However if I wish to change the date range I have to currently manually change every single date range.

Is there a way to link multiple plots to the same date range, by way of a user-defined variable?

Our processbook build version is 3.2.0.0 (Aug 2009).

Thanks,

Nathan
