How to display graphically vehicle journeys as link bar?
How to show volumes or other attributes of one or several vehicle journeys as link bar?
- Use the line filter to filter one or several vehicle journeys.
- Choose indirect attributes for the link bar (marked by one or two arrows denoting the relation of 1:1 or 1:n).
As it is an attribute of items (changing on the course of a vehicle journey), select a line 'item' attribute.
It works with the following bars for example for the volume:
1) Standard bar with attribute SumActive:Line route items\SumActive:Using time profile items\SumActive:Vehicle journey items\Volume (AP)
2) Using a line bar you already start with line route items. Attribute : SumActive:Using time profile items\SumActive:Vehicle journey items\Volume (AP)
'Using' means that the attribute is known for the PuT-route items (stop point to stop point), but the same value is available on the used links in between too.
You will find similar examples in the manual under 'Use cases for version comparison'.
