Mean value lines
If you select the Mean Value Lines dialog from the Insert menu, Calc calculates the
average of each selected data series and places a colored line at the correct level in
the chart.
Y error bars
If you are presenting data that has a known possibility of error, such as social surveys
using a particular sampling method, or you want to show the measuring accuracy of
the tool you used, you may wish to show error bars on the chart. Select the chart and
choose Insert > Y Error Bars.
Several options are provided on the Error Bars dialog. You can only choose one
option at a time. You can also choose whether the error indicator shows both positive
and negative errors, or only positive or only negative.
