[Paraview] Rescale & axes grid tricks

Mon Oct 23 08:09:22 EDT 2017

Cory, Alan and all ParaView experts,

I keep playing with two versions of Paraview following your kind advice,
thanks (see below, on Paraview 5.4.1 error message & freeze).

The earlier versions freeze sometimes as well, but I found a way to isolate
and avoid the bug (I just avoid making full screen or draw the screen
edges).

The recommended Paraview 4.4.0 I like the most, since it has button
"Rescale", which I find very useful: when you do threshold to remove
extreme values from the view, the picture looses contrast, and you can
rescale the color again.

 BUT in Paraview 5.2.0 I do not see "Rescale" button. So, after "Threshold"
all looks grayish & hard to understand what is what.

I then would stick to Paraview 4.4.0, but it has another drawback or a bug:
when I try to make visible Axas Grid & units, it works with 3D data sets
and 1D data sets (along one line), but does not work with 2D data sets.
Namely, it first appears, when I load the file, but after I click Glyph or
Threshold, the picture emerges, but the Axas Grid & units disapper! With
3D/1D data it does not, and you can enjoy seeing your full geometry. But
not with 2D, and I now mostly work with 2D  data. Paraview 5.2.0 has no
such problem.

SUMMARY:
Paraview 5.2.0 allows seeing Axas Grid & units, but does not allow Rescale
color.
Paraview 4.4.0 does not allow seeing Axas Grid & units with 2D data, but
allows Rescale.

Is there a way to enjoy both?

Thank you,
