### 9.7 Dividers

Dividers are called like this as they divide the chart to parts. Three types of dividers are defined. ‘`---`’ draws a horizontal line across the entire chart with potentially some text across it. ‘`...`’ draws no horizontal line, but makes all vertical entity lines dotted, thereby indicating the elapse of time.

The third type of divider ‘`|||`’ represents a simple vertical space. This can also be specified by entering just attributes in square brackets. The extreme ‘`[];`’ simply inserts a lines worth of vertical space. You can add text, too by specifying a label. See Dividers for examples.

Dividers take the `label`, `color`, `text.*`, `line.*`, `compress`, `vspacing`, `number` and `refname` attributes with the same meaning as for arrows. In addition, the type of the vertical line can be specified with `vline.*`, with `vline.type` defaulting to `dotted` for ‘`...`’ dividers and to `solid` for ‘`---`’ dividers. Other values are `dashed`, `none` and `double`. Again, note that the default values can be changed by using styles, see Defining Styles.
