You can fit various types of error bars to a data series in a column/bar chart or an XY graph. To do this:
Select a data series by Edit and then select one of the data series and double-click as when selecting a line for editing.
Then go Insert > Statistics and click on the error type and symbol type desired.
The result is shown in Figure 79.
Note that these error bars are calculated on the entire data series; that is, the error bars are equal at each point of the chart.
