My data is datetime, value pairs. I don't need to see the date, but the seeing time on the x axis is critcal.

The times are discrete minute intervals (5 minutes) with the first being 07:30:00 and the next 07:35:00 and so on.

How do I plot the x axis to show those times? Thanks.

Look at the DATETICK function.

Thanks.

The only problem is the axis is too crowded with labeling.

Is there anyway to get the labels vertical instead of horizontal?

How can I get the datetime to display in time format in a timeseries object?

It's just shows the datenum which is useless. Thanks.

I tried editing the callback to show a datestr instead of a datenum, but this didn't work. Any suggestions?

function output_txt = myfunction(obj,event_obj)
% Display the position of the data cursor
% obj Currently not used (empty)
% event_obj Handle to event object
% output_txt Data cursor text string (string or cell array of strings).

pos = get(event_obj,'Position');
output_txt = {['X: ',datestr(pos(1),4)],...
['Y: ',num2str(pos(2),4)]};

% If there is a Z-coordinate in the position, display it as well
if length(pos) > 2
output_txt{end+1} = ['Z: ',num2str(pos(3),4)];
end
