Hi,
I'm using tight_subplot from the file exchange to plot 4 similar graphs. I'm finding that, when I run my script, the x and y tick marks (i.e. 1,2,3...12) are disappearing for all 4 subplots. I'm not doing anything intentional to suppress them, but I am using a for loop to generate the four plots, which makes me wonder whether some information is being lost each time I end a loop.
Is there any sort of set command that I could use to bring these back up? Something like... set(ha(1:2),'XTickLabel','on')? (That doesn't work... ) I'd prefer not to have to actually assign the tick marks explicitly, but to get them from the metadata associated with the figures.
Thanks, Jonathan

If the plots are sufficiently close together, then the endpoints of the ticks might not be within the axes span: in such a case, MATLAB suppresses the line. This is the same case is if you have given specific axis limits and then you add a new line that starts or ends outside of the drawing area: the line will simply not be drawn. In order for MATLAB to draw a line, both endpoints must be within the clipping area.

Thanks for the information, Walter. Is there any way to recover the tick marks after Matlab has decided to suppress them?

Only by expanding the plotting area (and triggering a redraw.)

Once tick labels have been removed, I don't think they can be automatically regenerated: you have to add them explicitly using set(gca,'XTickLabel',[...]).
The better option, of course, is to prevent them from disappearing in the first place: tight_subplot contains the lines 'XTickLabel','', ... 'YTickLabel',''... Remove them and you're golden!

I know this question is old, but this had stumped me too for some time. It turns out calling "hold on" before a plot is generated causes the x and y tick marks to disappear.
My original for loop looked like this:
hold on, box on
for j = 1:5
plot(x,y)
end
The working for loop looks like this:
for j = 1:5
plot(x,y)
hold on
end
box on
Hope this helps! -Peter

Thanks for your comment Peter, its never too late for a solution. Even years later this is the problem, bringing the hold function inside the loop fixed it.

Thanks Peter. Works perfectly
