create a pie chart knowing the percentage value

12 visualizzazioni (ultimi 30 giorni)
I have the matrix 'matrix' characterized by the first column by numbers and the second column by percentage values.
matrix = [78,5 ; 79,6 ; 80,7 ; 81,11 ; 82,13 ; 83,15 ; 84,18 ; 85,16 ; 86,7 ; 87,1 ; 88,1];
I would like to create a pie chart that only takes into account percentage values <7.
So the matrix to be considered to create the pie chart would be 'matrix_new':
matrix_new = [78,5 ; 79,6 ; 87,1 ; 88,1];
How can I create the pie chart taking into account percentage values?
I should get something like this:

You can create a pie chart in MATLAB using the pie function, and to consider only the percentage values less than 7, you can filter your matrix accordingly. Here's the MATLAB code to achieve this:
% Your original matrix
matrix = [78,5 ; 79,6 ; 80,7 ; 81,11 ; 82,13 ; 83,15 ; 84,18 ; 85,16 ; 86,7 ; 87,1 ; 88,1];
% Filter the matrix to include only rows with percentage values < 7
matrix_new = matrix(matrix(:, 2) < 7, :);
% Extract the labels and corresponding percentages for the pie chart
labels = matrix_new(:, 1);
percentages = matrix_new(:, 2);
% Create the pie chart with labels
pie(percentages, labels);
% Display the matrix_new values in the pie chart
label_str = arrayfun(@(x, y) sprintf('%d (%d%%)', x, y), matrix_new(:, 1), matrix_new(:, 2), 'UniformOutput', false);
% Title for the pie chart
title('Pie Chart for Percentage Values < 7');
% Add labels to the pie chart
legend(label_str, 'Location', 'EastOutside');
