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>

<font face="Calibri, Verdana, Helvetica, Arial"><span style="font-size: 11pt;">I am told that EnSight find the range by loading the range from the last time step, which is where we got the idea. It might be more to it than that. Perhaps if the file format stores ranges over times it will load that and you data follows that?<br>

It loads the transient data range almost instantaneously. We just set a variable to paint the model and the color bar appears with a reasonable range for the transient data.<br>
<br>
Ken, setting the range by the last time step is a bit dangerous isn't it? For example, in my case, I'm 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>

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>

It seems like a potentially expensive choice since it requires loading every time step, but it would be worth having it as a simple option.<br>

Just to keep the question: <br>

Is there any simpler or automatic way to do that?<br>

Does anyone know if it's possible to rescale the color bar considering all values of a transient dataset? I just need to get the maximum and minimum values across all time steps.<br>

thanks for any help.<br>
