How can I plot the mean and standar deviation of two variables?

I have the mean of two variables and the standard deviation of the same variables, how can I plot error bars of this data so it looks something like this? I have used errorbar function but it doesn't work. Than you.

" it doesn't work" is rather meaningless here; you wouldn't be asking this question otherwise ;)

Better tell us which error you got, or why the result was different from what you expected, etc.

You could start like this:

meanVal = [.6, .6];
sdVal = [.4, 0.4];
errorbar(meanVal, sdVal, 'o');
set(gca, 'XLim', [0, 3], 'YLim', [0, 1.2])

Thank you, it's what I needed.
