circle graph in matlab

To create a circle graph or a pie chart in Matlab, we can use the pie() function.

The pie() function takes in a vector of values and plots a pie chart with each value representing a portion of the circle. Here is an example code to create a simple circle graph in Matlab:

main.m
% Create a vector of values
values = [20 30 40 10];

% Create a cell array of labels
labels = {'Group A', 'Group B', 'Group C', 'Group D'};

% Create a pie chart
pie(values, labels)

% Add a title to the graph
title('My Circle Graph')
235 chars
12 lines

In this example, we create a vector values with four values and a cell array labels with four labels. We then pass these values and labels to the pie() function to create a pie chart.

We can customize our circle graph by using additional input arguments to the pie() function. For example, we can change the colors of the portions of the circle or add percentage values to the labels.
