So i want a function to give me date (value: 1x1 table) as an output and a figure (polarhistogram), but when the function doesnt give an error i wont get a figure. Only when i type some random function with some random variables inside of that function it gives a figure as an output but after that my whole script stops.

So how do i get this line of code below as an output in a figure?

figure
h = polarhistogram (deg2rad(x),deg2rad(y));
Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

When simpely demanding h as an output i get this message:

handle to deleted Histogram

The only sections needed to run are 1, 3, 9

But i want this as an output of my function:

Btw windrichtingen means winddirections in dutch.

Unrecognized function or variable 'FahrenheitToCelcius'.

Thanks for all the effort but i found out what the problem was. I plotted another graph without creating a new figure so my polarhistogram disappeard. So only when i created an error I could see the polarhistogram.
