add more tick labels to a datenum graph

How can I add more tick labels to my graph? When opened I only get two tick labels and now and again I wont change anything and it will give me 5 or 6 labels. Is there a way i can speciify exactly how many labels i require?

function plot_tide_data(tidedata)

figure(1)
clf
plot(tidedata.t,tidedata.h,'b-')
datetick('x','dd/mmm')
xlabel('Day of Month','fontsize',15)
ylabel('Tidal Height (m)','fontsize',15)
set(gca,'Xminortick','on')
set(gca,'Yminortick','on')
set(gca,'tickdir','in')
grid on
set(gcf, 'PaperPositionMode', 'auto');
set(gca,'linewidth',2)
u = get(gca,'XtickLabel');
set(gca,'XtickLabel',u,'fontsize',20)
set(gca,'linewidth',1.5)
xlim([737739 737750])

Adjust xtick axis property.

This method below specifies 6 ticks that start and end at your existing tick bounds

ax = gca(); 
ax.XTick = linspace(ax.XTick(1),ax.XTick(end),6); 
%---------------------------------------------^ 6 ticks
