plotting a pie chart
显示 更早的评论
Hi I am Having trouble getting this chart to come up, I want to plot a pie chart showing the name of the country and what piece of the pie it takes up, this is my code so far..
countries= [ US Mexico Canada Cuba Guatemala DominicanRepublic ElSalvador];
pop= [309975000 108396211 34207000 11204000 14377000 10225000 6194000];
total= sum(pop);
percentage= pop/total;
% Create a pie chart with sections 3 and 6 exploded figure;
explode = [0 0 1 0 0 1 0 0];
pie(percentage, explode, countries);
% Add title
title('Populations');
Thank you

This works (although will need some refinement, which will be obvious when you run the code).
I did a couple things. I converted your countries variable to a cell array. Also, your explode variable was length 8, so I arbitrarily took off the last zero.
countries= {'US','Mexico','Canada','Cuba','Guatemala','Dominican Republic','El Salvador'};
pop= [309975000 108396211 34207000 11204000 14377000 10225000 6194000];
total= sum(pop);
percentage= pop/total;
% Create a pie chart with sections 3 and 6 exploded figure;
explode = [0 0 1 0 0 1 0];
pie(percentage, explode, countries);
% Add title
title('Populations');
