[IDV #FBN-526804]: Data probe/time series auto axis in bundle

I understand the problem that you are describing, but unfortunately there may 
not be a quick solution. We would have to come up with a heuristic to correctly 
fit the data and expose that functionality through the ISL. As far as I can 
tell, this capability does not exist presently via an ISL mechanism. If you 
want to sink your teeth in, you may also wish to look at IDV's Jython 
capability which theoretically would allow you to dynamically set the range.

Looking back in the archive there are a few support threads that may be of help:
