For links and connectors, you can display the difference between two attributes of a network object by a single bar. With flow bundle volumes, you can display the difference between two attributes of an OD pair accordingly by one bar. With turn volumes, you can display the difference between two turn attributes by one bar.
The width of the bar indicates the difference of the two attribute values. Via the classification settings, you can classify the differences. Additionally, the classes can be distinguished by color.
