Splitting a Colorbar into 12 parts according to months from data

Hi,
Im trying to use the month function and a for-loop to find and plot specific data according to different months, for example january would be red and february would be blue. I have been trying to have 12 different colors for each month corresponding to each data set.
Thank you

What is the difference between this and https://www.mathworks.com/matlabcentral/answers/1600850-splitting-a-colorbar-into-12-parts-according-to-months-from-data?s_tid=srchtitle ?

I think this question and answer are at least general enough to be useful to future searches.

If you're doing a line plot, it may make more sense to just use a legend.
% the selected colormap
cmap = jet(12);
% dummy data
x = 1:30;
y = rand(12,30)+(1:12).';
% plot setup
hp = plot(x,y);
set(gca,'colororder',cmap)
monthnames = {'Jan','Feb','March','April','May','June','July','August','Sept','Oct','Nov','Dec'};
legend(hp,monthnames);
If you really want to use a discrete colorbar that way instead, you can.
clf;
% the selected colormap
cmap = jet(12);
% dummy data
x = 1:30;
y = rand(12,30)+(1:12).';
% plot setup
plot(x,y)
set(gca,'colororder',cmap)
% wrangle the discrete colorbar tick alignment
colormap(cmap)
cb = colorbar;
cb.Ticks = 1/24:1/12:1;
monthnames = {'Jan','Feb','March','April','May','June','July','August','Sept','Oct','Nov','Dec'};
cb.TickLabels = monthnames;
