plot_graph - general plot of a graph
plot_graph plots graph g in a Scilab graphical window. The optional arguments rep and rep1 define the parameters of the plot. If there are not given, a dialog box for the definition of these parameters is opened.
rep must be a row vector with 13 integer numbers which must be 1 or 2. The meaning of the values of rep are:
Frame definition: 1 = Automatic 2 = Given (see below)
Plotting arrows: 1 = yes, 2 = no
Plotting sink and source nodes: 1 = yes, 2 = no
Plotting node names: 1 = yes, 2 = no
Plotting node labels: 1 = yes, 2 = no
Plotting arc names : 1 = yes, 2 = no
Plotting arc labels: 1 = yes, 2 = no
Plotting node demand: 1 = yes, 2 = no
Plotting edge length: 1 = yes, 2 = no
Plotting edge cost: 1 = yes, 2 = no
Plotting edge min cap: 1 = yes, 2 = no
Plotting edge max cap: 1 = yes, 2 = no
Plotting edge weight: 1 = yes, 2 = no
If rep(1) is 2, the frame definition must be given by rep1. Otherwise, rep1can be omitted. rep1 must be a row vector [orx,ory,w,h] giving respectively the coordinates of the upper-left point, the width and the height of the plotting rectangle.
