I wanted to color my scatter plot by date. I was able to do that with the code below but I want to me able to discrimate between dates better than just the month labels. Can I force the colorbar labels to be Month and Date? The code I am using does this fine if I plot the scatter plots by themselves but not as part of another figure. (maybe it is a size issue). This is how I am plotting now (see figures attached):

ax(3) = subplot(2,2,4)

% plot(b_range(k1+3:k2),Bmean3637(k1:k2-3),'.','color','k','markersize',15)

scatter(b_range(k1+3:k2),Bmean3637(k1:k2-3),[],btimestamp(k1+3:k2),'filled')

set(gca,'fontsize',16)

xlabel('Daily pH Range (1 mab)')

ylabel('BEUTI (3-day lag)')

colormap(jet);

h = colorbar; datetick(h,'y','keeplimits');

I understand that you want to label the colorbar with month and day, even if it is plotted as a subplot.

Generally, when the size of a figure changes, labels get squeezed as an expected behaviour. Kindly have a look at this possible workaround/solution.

b_range = (8.1-7.75)*rand(82,1)+7.75; 
Bmean3637 = 25*rand(82,1)-5; 
c=linspace(1,10,82); 
ax(3) = subplot(2,2,4); 
scatter(b_range,Bmean3637,[],c,'filled') 
set(gca,'fontsize',16) 
xlabel('Daily pH Range (1 mab)') 
ylabel('BEUTI (3-day lag)') 
colormap(jet);  
labels = {'07/08','07/15','07/22','07/29','08/05','08/12','08/19','08/26','09/02','09/09','09/16','09/23','09/30','10/07'}; %explicitly indicate the labels 
h = colorbar('Ticks',1:14,'TickLabels',labels,'limits',[1 14]);
