Problem 55420. Power Outages Histogram

Created by Renee Coetsee

Solve Later

Create a function that takes power outage data as an input and creates a histogram of the number of outages as a function of Region. Note that the Region column of the power outage table contains a cell array of character vectors.
Rotate the x-axis tick labels by 30 degrees and label the y-axis with "Number of Outages".
Your function should return the figure handle as output.

The function is not executed for any of the tests.

Execute scratch pad:
T = readtable("outages.csv","TextType","string");
g__= plotOutages(T);

We must use the scratch pad, as said by David Hill, and return the histogram with gcf(). This should probably be added to the problem's description.

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
