Changing the color of stacking bar plot with many groups

1 visualizzazione (ultimi 30 giorni)
I have a big matrix with size of 28 X 10 and I used bar plot (stacking) to plot them. Now I'm struggling to change the color for all the 28 variables. Any to make them look different so i cant distinguish them.
figure
students = rand(28,10);
year = 2020: 2029;
bar(year, students, 'stacked')
legend('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'Z')

students = rand(28,10);
year = 2020: 2029;
h=bar(year, students, 'stacked') ;
legend('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'Z')
c=colormap('jet');
pick=round(linspace(1,size(c,1),numel(h)));
c=mat2cell(c(pick,:),ones(1,numel(h)),3);
[h.FaceColor]=deal(c{:});

Is there a way to make some of them with grid color or something that would make them noticeable rather only by color?

Every group will be a bar object. You can check the documentation which properties are available for you to edit.
If you can't edit all properties you want, you may need to build it yourself from patch objects instead. You could see if there is something suitable on the FileExchange.
