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 =

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