#### 9.2.1 Entity Positioning

Entities are placed on the chart from left to right in the order of definition. This can be influenced by the `pos` and `relative` attributes.

Specifying `pos` will place the entity left or right from its default location. E.g., specifying `pos=-0.25` for entity `B` makes `B` to be 25% closer to its left neighbour. Thus `pos` shall be specified in terms of the unit distance between entities. (Which is 130 points - a historic value kept for backwards compatibility.)

The next entity `C`, however, will always be from a unit distance from the entity defined just before it, so in order to specify a 25% larger space, on the right side of entity `B`, one needs to specify `pos=0.25` for `C`.

The attribute `relative` can be used to specify the base of the `pos` attribute. Take the following input, for example. In this case `C` will be placed halfway between `A` and `B`.

Note that specifying the `hscale=auto` chart option makes entity positining automatic. This setting overrides `pos` values with the exception that it maintains the order of the entities that can be influenced by setting their `pos` attribute. See Chart Options. In most cases it is simpler to use `hscale=auto`, you need `pos` only to fine-tune a chart, if automatic layout is not doing a good job.
