Use the Reference Line dialog box to select the type of data to associate with the reference line, and to specify general reference line properties.
Table 78. Reference Line Properties
| Property | Description |
|---|---|
| Fixed | Enable to assign a fixed value to the reference line (axis based). This option is used in conjunction with the edit field and Axis field. When this option is enabled the “Fact” field name is changed to the “Axis” field name. |
| (edit box) | Specify the fixed value amount to use for the reference line. The amount must be numeric. It remains constant on the reference line, and does not depend on another item in the Fact pane of the data layout. |
| Axis | Select the fact axis on which to position the reference line. Available axes:
Note: A reference line can be added to the X axis only if the axis continues as in the case of the Scatter and Bubble charts. If the fixed value assigned to the reference line is beyond the data ranged shown on the fact axis, and the axis is auto scaled, the data range is expanded automatically so the line can appear. |
| Fact | Select the fact based column for the reference line from the drop-down. Available columns are based on the columns in the data set. |
| Function | Select the function to apply to the fact based column. Available functions are:
|
| Bring to front | Positions the reference line in front of the chart item. |
| Send to back | Positions the reference line in back of the chart item. |
| Show in legend | Enable to show assigned text of the reference line and short line segment representing the actual color of the line in the legend. |
| Show label | Enable to show the label text on the diagram. |
