Description

plybar plots a vertical error bar centered around the current position The total length of the bar is range and is meant to indicate the range of the data represented by the bar. Two crosses with a width of 2 mm are drawn at equal distances sd above and below the starting point. The distance between the crosses is thus two times sd. They are supposed to indicate the standard deviation in the data represented by the error bar.
