The cost function takes a cell and returns it's cost as a double. Two typical
|
|
examples of cost functions are the euclidian length of edges or a constant
|
|
number for each edge. To use one of the built-in cost functions, use either
|
|
<code>new mxDistanceCostFunction(graph)</code> or
|
|
<code>new mxConstantCostFunction(1)</code>.
