I am working with 3D axes. Previously I have modified the z and y axes. I needed to have z and y values shown reversed. Not to go from 1 to 200 bit from 200 to 1. And now data cursor fetches the old data and is not in match with on screen data.

Any help would be appreciated.

Thanks.

note: I have changed the values like this:

yLimits = get(gca,'YLim');
yTicks = yLimits(2)-get(gca,'YTick');
set(gca,'YTickLabel',num2str(yTicks.'));

Without checking, I think the ticklabels are just some text - could be any text. It doesn't change the underlying scale of the axis.

What more did you do to "have z and y values shown reversed"?

Try this instead:

set(gca,'YDir','reverse')

Your way retains the y tick locations and values, and just labels them with something else. For example, it may place the string "2.0" at the spot corresponding to y=1.0.
