Create Categorical array for histogram on R2020a

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.

Steve when I run OP code on my laptop I get this on the command window (R2022a, Windows 11, Intel Irish XE Graphic card, latest driver installed)

h = 

Histogram with properties:

Data: [no    no    yes    yes    yes    no    no    no    no    undecided    undecided    yes    no    no    no    yes    no    …    ]

DisplayOrder: 'data'
Normalization: 'count'
DisplayStyle: 'bar'
FaceColor: 'auto'
EdgeColor: [0 0 0]

I works fine however if I do this before (may be a work around for OP)

on other PC with different (Nvidia graphic card).

Odd and I have no ideat what to chase.
