Bar graph don't work on matlab R2015B

Before, I used R2013B release. I often used the bar function. But now, I have the R2015B release and then, the bar function don't work

for example:

y = [75 91 105 123.5 131 150 179 203 226 249 281.5];
bar(y)
Warning: Error updating Bar.

   Struct contents reference from a non-struct array object.

What does

which -all bar

show? Looks like you may have aliased the builtin--and I note the spelling in the error of Bar rather than bar which seems peculiar.

Hmmm...well, that looks ok. I presume you've tried things like restarting and the like? If still no joy, looks like time for a service request to TMW @ www.mathworks.com
