I was trying to make a plot bar as shown in the documentation web:

https://es.mathworks.com/help/matlab/ref/bar.html

c = categorical({'apples','pears','oranges'});

prices = [1.23 0.99 2.3];

bar(c,prices)

And in matlab 2018 works fine, but now i am trying that example with matlab 2014, and its not working... How can i plot a name for each one of the plots?

thanks in advance!

edit: the error message is this one:

Undefined function 'minus' for input arguments of type 'categorical'.

Error in bar (line 62) if any(sortedx(2:end)-sortedx(1:end-1) == 0)

<Answer_259279> bar wasn't smartened-up enough to know about categorical variables for labels until later; not sure which release included it, but R2014b is too early.
