The main options of interest for flow maps are the scaling model and the display width. The following
scaling models are available:

Linear: the width is determined by relating the flow quantity to the sum of all flows for the same
scenario.

Log: the width is determined by multiplying the log of the relation between the flow quantity and
the minimal flow with the log of the relation of the maximal and minimal flows for the same
scenario.

Polynomial: the relation between the current flow and the maximal flow is raised to a power
determined by taking the log of the relation between the maximal and minimal display width
divided by the log of the regional between the maximal and minimal flow.
The user can prevent that small flows are drawn by setting a minimal width relative to the size of the
window; equally, the maximal possible size of a flow relative to the size of the window can be
determined.
In order to show only a selection of the flows, the selection
buttons can be used. The lower left
one relates to the rows of the underlying tables, and thus allows excluding origins from the maps. The
lower right one opens a dialogue to exclude destinations, whereas the upper right one allows exclusion
of scenarios.
