I have a figure that has axis already and numbers in them. I wish to change the axis values display values so that they read differently. I only have the .fig file and the numbers on the axis don't matter to much, so changing them is only for better readability (say put in in a positive scale from 0 to 10. How does one do that without screwing up the figure?

ax = findobj(0, 'type', 'axes', '-or', 'type', 'matlab.graphics.axis.Axes');
if isempty(ax); error('No axes found'); end
if length(ax) > 1; error('Multiple axes found'); end
xticks(ax, [new list of x tick positions])
set(ax, 'XTickLabel', {'0' '1' '2' '3'});

I think it would be nice to note to future readers what ur code does with some comments.
xticks(ax, [new list of x tick positions])
is the "real" actual values on the axis and:
set(ax, 'XTickLabel', {'0' '1' '2' '3'});
is the new display "labels" that will appear on the figure. I made the `[new list of x tick positions]` be the same length as `{'0' '1' '2' '3'}`, one new display label for each true value on the axis.
thanks!
