Thank you so much Phyllis, for the info and your time!
I have done very quickly test about Histogram with Cin_20200920_release 
by git.

My considerations and comparison (Preferences/Color/YUV color space= 
Histogram Bezier plugin uses Log instead of Linear.
I don't understand what type of histogram View Scope tool uses in its 
Histogram? Log, Linear or 50%?
When the Color Model format (in Settings->Format...) is set to RGB[A] 
the histogram displayed on Histogram plugins is the same as on Histogram 
Bezier plugin.
If you change Color Model format from RGB[A] to YUV[A] the histogram on 
Histogram Bezier no changes, but on Histogram plugin and on View Scopes 
it changes. It is strange, I think.
In Histogram Bezier plugin the histogram doesn't change in the 
differents color model.

Any yours considerations about?
