Color bar rescaling for transient datasets<BR></FONT><BR></DIV>
<DIV></DIV>What about interpolating the ranges in a regular number of time
steps? For instance, let's say we have a dataset with 100 time steps. Instead
of loading all files to find the correct range, we could have an estimative by
computing the maximum and minimum values using only 20 or 50 time steps. Maybe
the user could choose how many time steps should be skipped.<BR><BR>more two

coloring a dam break fluid flow model by the velocity magnitude. In this
problem we stop the simulation after the fluid rests in a static position.
Therefore the last time step velocity should be almost
zero.<BR><BR>Renato.<BR><BR>On Thu, May 14, 2009 at 10:33 AM, Moreland,

<DIV class=im>This issue has come up quite a bit. We are trying to
think of a way to set the range reasonably while avoiding expensive
loading and maintaining consistent behavior. One idea we are
considering is to set the range based on the last time step, which often
has a range close to the full range.<BR><BR>-Ken<BR><BR><BR><BR></DIV>

<DIV class=im>Ok, I've just found a way using the "Temporal
