You can use the Y Error Bars window to display error bars for 2D charts.
If an element of a data series is selected, this command works on that data series only. If no element is selected, this command works on all data series.
An error bar is an indicator line that spans over a range from y - NegativeErrorValue to y + PositiveErrorValue. In this term, y is the value of the data point. When Standard Deviation is selected, y is the mean value of the data series. NegativeErrorValue and PositiveErrorValue are the amounts calculated by the error bar function or given explicitly.
