TreePlot(tree, opts, plotopts)
tree
-
binomial or trinomial tree data structure; tree
opts
(optional) equation(s) of the form option = value where option is scale; specify options for the TreePlot command
plotopts
(optional) options to be passed to the plots[display] command
scale = default, exponential, or logarithmic -- This option specifies whether the tree should be plotted using the exponential, logarithmic, or the default scale.
The TreePlot command plots the specified binomial/trinomial tree.
The tree is displayed using the plots[display] command. All unprocessed arguments are interpreted as plot options and will be passed to the plots[display] command when the final plot data structure is generated.
