Summary0007564: color map and time varying data
DescriptionIt would be useful if the color map had an option to automatically adjust to the data range of the currently displayed color map. The option would require a suitable warning that the colors drawn can be misleading. The option can be useful when you are using a color map to look at the location or relative maximums and minimums, and don't care about concrete values that each color represents.

It would also be useful if we could add a mechanism whereby the complete data ranges over all time can be used to set the color table ranges. This would color the data correctly and at the same time not "range out". True this can be done manually, but when the number of arrays gets large, doing it manually is not feasible.

The complete range would often be too expensive to compute automatically, but if the simulation produces those values as meta data, they could be used to set up decent initial values. I think that if the reader forces them into vtkDataArray's per component range info keys it will propagate and work for most cases when automatically rescale is turned off.

This was a request from Jim's group at LANL.

 I've added a Track Scale Changes checkbox so that you can automatically recompute min max whenever time changes.

Does this work as expected?

(I have not addressed the meta-data question)

 I cannot find a button that says "Track Scale Changes". Where is it?

 Parts of this are already handled. We have a "Rescale Data Range Mode" in the application settings dialog.

There are other bugs that talk about keeping temporal data which will also help with this one.

 I think I will push back on this one. I have had users ask for this functionality, and cannot find it in any other bug reports. Furthermore, Ken keeps pushing back against it, but users still ask for it.

Specifically the user is asking to automatically update the color range every single time step (not grow). This may be desired if you are running over many timesteps, and you are looking for locations of min or max, but don't care about the size. An example (I am totally inventing here) would be where the highest pressure of a gas is in a car engine. Pressure changes every time step, but the gas pressure patterns would still be interesting.

 We still desperately need this - the option (not used as default) to allow min and max to automatically change every time step to fit this time step's data. Useful where you are looking for patterns in data that changes units many orders of magnitude over time.

 Putting on todo list - we really should do this one.

    Reset/grow LUT as timestep changes.
    
    vtkSMAnimationScene now respects the vtkPVGeneralSettings to reset or
    grow the transfer functions as the animation plays.
