It seems like this example on Histogram plot - MATLAB - MathWorks Italia :

A = [0 0 1 1 1 0 0 0 0 NaN NaN 1 0 0 0 1 0 1 0 1 0 0 0 1 1 1 1];
C = categorical(A,[1 0 NaN],{'yes','no','undecided'})
h = histogram(C,'BarWidth',0.5)

does not work on 2020a.

Any workaround?

I tried running those three lines of code in release R2020a and it produced the categorical histogram plot that I expected.

What does "does not work" mean in this context?

Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support so we can investigate.
