MATLAB: How to match the datetick

datetickx axis

Hi all,

I've attached the plot that I want to correct the datetick (it doesn't match with the real date). Could anyone help, please?

thanks in advance.

h = openfig('AugWnd.fig');
ax = get(h,'CurrentAxes');
ax.XAxis.TickLabels = cellstr(datestr(ax.XAxis.TickValues/24 + datenum('2017-08-01'),'dd-mmm'));

Note that the ticks are 100 hours apart. You might want to consider changing ax.XAxis.TickValues to [0:96:799, 800] to get every 4 days plus the end point.

That's because datetick is a bit clunky, and it can't get a lock on a date that it thinks is worthy of displaying. Probably because your date range is somewhat short. For example, here's a year of data:

t = datenum(2005,1,1:365); 
y = sind(t); 
plot(t,y,'bo-') 
datetick('x','DD/mm','keeplimits')

But if you only have 5 days of data it can't find a good match:

t = datenum(2005,1,1:5); 
y = sind(t); 
plot(t,y,'bo-') 
datetick('x','DD/mm','keeplimits')

But you can specify xticks manually. Let's set an x tick every other day:

set(gca,'xtick',t(1:2:end))
datetick('x','DD/mm','keepticks','keeplimits')

MATLAB: Set specific date ticks

datetick('x', dateFormat, 'keepticks')
