timetick

Time formatted tick labels.

Description

TIMETICK sets current axes to time formatted tick labels. X Axis must be time, in datenum format.
 
TIMETICK(AX) sets axes with handle AX to time formatted tick labels.
 
TIMETICK(AX,precision) sets axes with handle AX to time formatted tick labels with precision values to the right of the decimal for seconds specifier.

Use TIMETICK instead of DATETICK when you want fractional second precision. Unlike DATETICK, TIMETICK works well with ZOOM.

See also TIMESTR.

It did not work for me in 7.0.1.24704 (R14) Service Pack 1 although timestr worked. I received the message below. Hope the author will fix it soon.

>> timetick('x', 'HH:MM:SS.SSSS')
??? Error using ==> get
Invalid handle.

Error in ==> timetick at 26
xt = get(ax,'XTick');

Implementation can be improved. I improved its capability to include all axis's. The timestr function seems a little involved since it is performing datestr for however many ticks you have chosen.

If anyone has come to a solution on how to update the tick labels after zoom let me know.

Thanks

And now in English.
fmt = ['%02d:%02d:%0' totalwidth '.' precision 'f'];

The leading zero also works on fixed-point. For example, if the seconds format is '%07.4f', a seconds value of 0.440 seconds comes out as '00.4400'.

I aded some more edits, I can't seem to upload them, though.

To resolve the error mentioned in 2nd reply, just use timetick
without any input. Default is x axis.

What about if you have a long time series (years) and want output in YYYY-MM-DD? This function only seems to be relevant for second/microsecond time periods????? Any ideas? Thanks.

My bad - just found the datetick() function. Please ignore previous post...
