y-axis only absolute values

Hi folks,

Is there a easy way to set the y-axis values to their absolute values such that there are only positive numbers on the y-axis?

Thank you for answers,

Cheers Sam

What do you want to do about the negative values in your plot? Just not show them?

Sure,

plot(x,abs(y))

I'm guessing that's not what you mean, precisely, however. If you mean instead to simply display abs() of tick labels even if the y-limits include some negatives, then try

   set(gca,'yticklabel',num2str(abs(get(gca,'ytick').')))

Thank you very much. That's exactly what I meant. Maybe I should have said that I don't wanna change any plot-data ;)

Then please accept an answer so others won't needlessly try...

yl=get(gca,'ylim')
ylim([0 max(yl)])
