Problem 55420. Power Outages Histogram

i am so confused, i dont think any of the test cases actually execute the function ?

@March 7th, the part of the test suite where the function is called is before the first test and so isn't visible.

Dear all
"assert" had been defined like below;
assert(isequal(g__.Children.Children.Type,'categoricalhistogram'))

If you want to pass the tests, you should define you function like below

wrong function:
function f = plotOutages(T)

end

Right function
function g__ = plotOutages(T)

end
