how to use the "tight" function for just one axis

So I origionally had: axis tight But it cut both axes, whereas I just want it to be tight around the x axis but allow the y axis to not be cut. Is there a function for this please? Thanks

Not at hand, but it's not difficult to do...

function ytight(ax)
  % Set axis tight only on y-axes
  yl=xlim(ax); % retrieve auto y-limits
  axis tight   % set tight range
  ylim(ax,yl)  % restore y limits 
end

You can also actually compute min, max of X-axis data and just set it, which is what is done

xlim([min(x) max(x)])

Thanks, I'll give that a go, but which variable does ax represent please? Thanks!

[Jamie Shelley]

I did it the second way you said and it worked, thanks!

"which variable does ax represent?"

The axes handle in question...typically the result of gca, but having it as an argument to the function lets the function be used in general, not just on the current axes. "Mo' bettah!" would be to make it optional and default to gca, but that was more coding effort than wanted to go to at the moment...

xlim can actually do this without manually setting the limits:

xlim('tight')

which I have added as a seperate answer below.

There's an out-of-the-box command for what you want:

set(handleToAxes, 'XLimSpec', 'Tight');

or

set(handleToAxes, 'YLimSpec', 'Tight');

I found it didn't work with "handleToAxes" but it did with "gca" instead. Thank you! :)

Undocumented properties! But useful. How many undocumented properties are there?

Undocumented...

Documentated Function:

xlim('tight')

As of R2021a, the best method to do this is:

ax = gca()
ax.XLimitMethod = 'tight'
