If not, then doing - 2 std_x is probably conceptually faulty. –lijie Dec 10 '10 at 5:52 Normally I can think of taking +/- about the mean for a For a symmetric distribution (in particular, say, normal distribution), taking low = mean-K std and high = mean+K std makes sense because the range is the smallest possible. If you mean you want symmetric errors on log scale then compute and pass the lower/upper limits when call errorbar() instead of using a single error value doc errorbar -- Subject: To add items to your watch list, click the "add to watch list" link at the bottom of any page.
