how to increase the number of values displayed on the X-axis matlab

Hi!

I have a couple of points that their y value is changing with date. When I plot it regularly it is fine but when I plot it in a subplot it automatically does not show all the dates in x axis and just show the min and max date. I was wondering how I can get Matlab to display all the points. Attached please find the plots.

Thanks :)

That's probably all it thought it could comfortably fit. Look up tick marks and tick labels in the help to see how you can manually set them with the set(gca, 'XTick'...) and set(gca, 'XTickLabel',.....) function calls.

I actually tried to input the x-axis through "set(gca,'XTick',...)" but it did not work and I guess it is because I am using datetick('x',6) ..

you'll have to do something like this after you create the subplot.

newLim = get(gca,'XLim'); 
newx = linspace(newLim(1), newLim(2), 10); 

set(gca,'XTick', newx); 
datetick(gca,'x','HH:MM:SS','keepticks');

you'll have to play around with the number of ticks created with the linspace due to the limited space to display the day/time.
