Dear everyone,
I have a pressure scalar field as a plane, to better visualize maxima and minima, I usually rescale the colorscheme to a range between -1 and 1 and then I play with the opacity mapping until I see only really low and really high zones as blobs.
Now, I would really like to put some contours on these blobs, but the data in itself is not scaled, so I can’t put contours directly on the normalized scale…
Is there a way to rescale data to custom range with a calculator or something like that, so that I can put the contour on the range from -1 to 1 and not the original one?
Thanks a lot and happy festive days
