X/Y Error Bars
Use the X or Y Error Bars dialog to display error bars for 2D charts.
An error bar is an indicator line that spans over a range from x/y - NegativeErrorValue to x/y + PositiveErrorValue. In this term, x or y is the value of the data point. When "standard deviation" is selected, x or y is the mean value of the data series. NegativeErrorValue and PositiveErrorValue are the amounts calculated by the error bar function or given explicitly.
The Insert - X/Y Error Bars menu command is only available for 2D charts.
