Requirements for Showing Arrows

Showing arrows is available for a map if the following conditions are satisfied:

Two territory dimensions should exist in the map data source. Both territory dimensions should meet general requirements for working with a map.
Roles for the following dimensions are specified for a map: observation objects dimension (first territory dimension, from which the arrow starts), arrow direction dimension (second territory dimension, to which the arrow is directed), and metrics dimension.
A metrics dimension is set up. Elements of a metrics dimension and the following characteristics are mapped:

Arrow color. Select the Arrow Color radio button on the metrics dimension tab and select the element, by which values arrows will be colored.
Arrow thickness. Select the Arrow Thickness radio button on the metrics dimension tab and select the element, by which values the arrow thickness will be determined. This characteristic is optional.
