How to use MATLAB to draw a pie chart

Pie tools in matlab can draw pie charts
X = [1 3 0.5 2.5 2];
Explode = [0 1 0 0 0];
Pie (x, explode)
Explode separates the number of items from others. If the value in explode is not zero, it will be separated. It starts to rotate counter-clockwise from the center. You can try it on your own.
Pie3 is a three-dimensional image of a pie chart. You can enter doc pie3 in the Command window to see the specific explanation!

When MATLAB draws a pie chart, x = [11 28 05 25 2]; explode = [0 1 0 0 0] How is the percentage determined by this?

1.1, 2.8 indicates the proportion, 1.1/1.1 + 2.8 + 0.5 + 2.5 + 2 = 1.1/8.9, generally the proportion of the pie chart calculated by percentage,
In explode, 0 indicates that the two slices are combined. 1 indicates that the two slices are separated. I don't know if it is clear. I hope it will help you ,.
