How to add labels to a pie chart.

Hi all, I want to add labels to a chart that is made out of a vector given by the user, and if the sum of the given numbers is less then 100, then the pie will show the percentage of each number, the deduction differnce will be labeld 'other'. I don't know how many numbers the user gives.

example [1,5,6,8]

will sow 1% 5% 6% 8% and the (100-20=80) will be labeld 'other'

Hi @Sara Thoms,

To get the deduction difference of the vector elements from 100 and label it in the pie chart as ‘Other’, you can follow the given steps:

• Append the difference (100 – sum(vector)) to the given vector itself.
• Append the ‘Other’ label to the labels array.

You can refer to the following code as an example:

x = [10, 20, 40];
other = 100 - sum(x);
labels = ["first", "second", "third"];

if other > 0
    x = [x, other];
    labels = [labels, "other"];
end

pie(x, labels);

For additional guidance, you can refer to the MATLAB Documentation on the “pie” function:
