Datetickzoom - automatically update dateticks

Label axis with date ticks that automatically update when zooming or panning

Description

DATETICKZOOM behaves completely identical to DATETICK, except that tick labels are automatically updated when zooming or panning.

• MATLAB release: MATLAB 7.3 (R2006b)

Very useful, thanks!

One remark: it seems that datetickzoom uses the input argument dateform=0 by default, even if a second input argument is given. For instance, datetickzoom('x',1) should display labels in the form 'dd-mmm-yyyy' whatever the zoom. Instead, it automatically switches between different dateforms when zooming.

[Christophe Lauwerys]

Concerning your remark: the switching between different dateforms is desired behavior since, in my opinion, the resolution of the ticks should increase when zooming in.

Very nice. This has been an annoying aspect of MatLab for some time. Thank you.

[Rajesh Rajaram]

It is a very nice option to add to matlab. It works great on a single plot.

However I am not sure how I could use it when I also need to use the linkaxes option to link multiple subplots.

[Carlos Adrián Vargas Aguilera]

Excellent job! Congratulations Christophe! I made a modification of your function and MATLAB's to put what is left by the ticks on the date-axis.

Rajesh: if time is in X-axis you can use
a = linkprop(h, {'XTick', 'XTickLabel', 'XLim', 'YLim'});
where h are your axes handles. And to link the label too:
b = linkprop(cell2mat(get(h,'XLabel')), 'String');

Cheers

Hi Christophe,
I'm getting the error "One or more output arguments not assigned during call" in line 39 when using datetickzoom('x'). Any clue what I'm doing wrong?
Cheers
