On the edge courses you can display any attribute values of the underlying vehicle journeys, for example volumes. For the formatting of bars, especially for a classified display, the standard graphic parameters are provided (User Manual: Setting graphic parameters for the schematic line diagram). Unlike for link bars, the attribute value allocated to an edge is not constant over the entire course, because an edge symbolizes a set of vehicle journeys between any selected transfer nodes, so that the volume, for example, may differ at the hidden stopovers. Bars can thus be divided at the centered label and show the attribute values that each apply to the start transfer node and the end transfer node on the two sections.
To visualize transfer flows you can display bars between the incoming and outgoing edge courses within the transfer nodes. You can specify the bar display with the standard parameters.
