Barras de erro X/Y
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.

Funcións

Standard Error: Displays the standard error.
Variance: Displays the variance calculated from the number of data points and respective values.
Standard Deviation: Displays the standard deviation (square root of the variance). Unlike other functions, error bars are centered on the mean.
Error Margin: Displays the highest error margin in percent according to the highest value of the data group. Set the percentage in the Parameters area.
Intervalo de celas
Click Cell Range and then specify a cell range from which to take the positive and negative error bar values.
Dende a táboa de datos
For a chart with its own data, the error bar values can be entered in the chart data table. The Data Table dialog shows additional columns titled Positive X or Y-Error-Bars and Negative X or Y-Error-Bars.
Mesmo valor para ambos
Enable to use the positive error values also as negative error values. You can only change the value of the "Positive (+)" box. That value gets copied to the "Negative (-)" box automatically.
