Description

Line position

Specifies the type of line that you wish to add.

   Fixed value

Adds a straight line at the defined value for the selected axis.

   Aggregated value

Adds a straight line at the selected aggregation of values for the selected values.

   Column property value

Adds a straight line at the specified column property value. All numerical column properties, both predefined and custom properties, are available for selection.

   Custom expression

Adds a line at the specified custom expression.

   Edit...

Opens the Custom Expression dialog, where you can select between columns and functions to define your expression.

   Use axis transform in line calculation

Select this check box to apply the same axis transform, i.e., a log scale, to the reference line as has been previously specified on the page for the axis. A reversion of the axis is always applied.

Line name

Specifies whether an Automatic line name should be created, or whether you instead wish to type a Custom line name.

Note: If you change the orientation of the bars in a bar chart, any added lines will automatically switch orientation as well. For example, if you have added a horizontal line to a vertical bar chart and then switch to horizontal bars, the line will automatically become a vertical line.
