Create pie chart in if loop

Hello,

I´ve written the following loop

hold on
for i=2:1:48
    x=File.data(8,i);
    if x>10
        pie(x)
    end
end

My intention is to create a pie chart of the values in row 8 and columns 2-48 whith the condition thet the value in that cell is larger than 10 but i cant get it to work. Does anyone know what im doing wrong?

Thanks

From the documentation, "pie(X) draws a pie chart using the data in X. Each slice of the pie chart represents an element in X."

You need to provide all of the "slices" within the same input rather than one-by-one within a loop.

data = File.data(8,2:48);   % <--- a vector of all slices
pie(data(data>10))          % <--- only provide slices >10

In your loop, the pie chart is being overwritten upon each iteration and only shows 1 "slice" at a time.

I am not certain what you want, however the loop is likely not necessary.

Try this:

x = File.data(8, 2:48);

figure
pie(x(x>10))
axis equal
