preserve datetick labels when resizing

"datetick" prints dates on x-axis (e.g. "12/11/2011"), when the plot is resized, these dates are jammed together. How do I preserve the look?

Specicially I am printing the plot into powerpoint slides (using saveppt2.m from file exchange), the size changes, and I can't keep the same look.

Thanks, Hugh

This doesnt relate exactly to your problem - but this is wonderful code that resets the date ticks when you zoom in/out of graph with a date axis. Perhaps you could learn something from the code that will help with your situation.

It is probably easier (or at least more cleanly isolated) to create a uipanel that you put the plot in, and then to use the ResizeFcn callback to detect the size change; the code in that callback would figure out the new ticks to use and set() the axes XTick property (and perhaps the XTickLabel as well.)

The uipanel step is not needed; you could instead use the ResizeFcn figure property.

But when you say resized, do you perhaps mean zoomed? If so then there is a different mechanism to use for that: for that set zoom mode and set the ActionPostCallback property to something that sets "nice" new ticks.

Thanks Walter. I am not familiar on these commands. Could you tell specifically what I can do? Yes, it is not resized, it is zoomed when the Matlab fig was exported to PowerPoint.

Here's a small example that might help:

function test

plot( now : now+30, rand( 1, 31 ) );
datetick x;

set( gca, 'Tag', 'dateAxes' );
set( gcf, 'ResizeFcn', @resize );

function resize(src, evt)

ax = findall( src, 'Tag', 'dateAxes' );
datetick( ax, 'x' );

[Hugh]

Thanks. It is doing something but does not solve my problem. I will try to my code and data.

[Hugh]

Any way to attached a small data file?
