To turn a graph into a navigation graph you need to add one or more navigators. Navigator have their own set of states that can be queried and modified.
l_navigator_add(
widget,
from = "",
to = "",
proportion = 0,
color = "orange",
...
)navigator handle with navigator id
graph widget
The position of the navigator on the graph is defined by the
states from, to and proportion. The states from
and to hold vectors of node names of the graph. The
proportion state is a number between and including 0 and
1 and defines how far the navigator is between the last element of
from and the first element of to. The to state can
also be an empty string '' if there is no further node to go to.
Hence, the concatenation of from and to define a path on the
graph.
