Is it possible to use yticks only on one side?

Is it possible to use yticks only on one side? How to set?

[madhan ravi]

can you post your code?

[Adam]

YTicks are only on one side by default.

[Mr M.]

I used imagesc, and I have ticks on both sides.

[Mr M.]

simple code: imagesc(rand(100)), and you have ticks on all sides: left,right,top, bottom. How to remove yticks from right, and xticks from top?

[Adam]

I can't actually see any way to turn them off using sensible functionality. For the y ticks specifically you can use an ugly hack e.g.:

figure; imagesc( magic(25) )
yyaxis right
set( gca, 'YTick', [] )
set( gca, 'YColor', 'k' )

though I don't know a way to do it for the x axis and the above is horrible code. yyaxis is an ugly function since it gives no possibility to actually return the axis handle and instead just changes what is the current axes.

The yticks appear on both sides due to the box being 'on', so to say. Remove them by

box off

This will of course also remove the frame, so here is a bonus hacky solution for retaining the frame

imagesc(rand(100))
box off
ax=gca;
axes('position',ax.Position,'box','on','ytick',[],'xtick',[],'color','none')

Be careful with using 2nd axes though. You will lose the ability to zoom, pan, use the data cursor functionality etc, unless you hack around with it still further :( I've had to do this a few times and it's not much fun!

Seems like this should be an option for 'boxstyle', but currently there is only one option for 2D plots. In this specific case I think the extra axes is OK, because it is just an empty frame. You can still zoom if you have the primary axes as the current axes. You'd need to set the background transparent though

ax.Color='none'

so that the second axes is visible below the primary.
