Hi,

I have some statistical data from which I want to graph the means and use the STDsstandard deviations as error bars. However this produces a graph with some of the error bars passing below zero. A negative value is silly for this data (mean trip times), so I was wondering what is a sensible way to graph the data.

Thanks

Is it alright for STD error bars to be below zero?
