Undefined colororder error

[pcpollak]

Every time I try to run violinplot function on my own or the sample data I get the following error:

Undefined function or variable 'colororder'.

Error in Violin (line 168)
C = colororder;

Error in violinplot (line 161)
violins(n) = Violin({thisData}, n, varargin{:});

Does anyone know why this is happening?

Are you, by any chance, running a very old version of Matlab? colororder was introduced in 2019b.

Yes I am running 2019a
Thank you for pointing this out!
