.TH plot_graph 1 "September 1996" "Scilab Group" "Scilab function"
.so ../sci.an
.SH NAME
plot_graph - general plot of a graph
.SH CALLING SEQUENCE
.nf
plot_graph(g,[rep,rep1])
.fi
.SH PARAMETERS
.TP 3
g
: graph list
.TP 4
rep
: row vector of 13 values for the parameters of the plot
.TP 5
rep1
: row vector of 4 values defining the plotting rectangle
.SH DESCRIPTION
\fVplot_graph\fR plots graph \fVg\fR in a Scilab graphical window.
The optional arguments \fVrep\fR and \fVrep1\fR define the parameters
of the plot. If there are not given, a dialog box for the definition
of these parameters is opened.
\fVrep\fR must be a row vector with 13 integer numbers which must be 1 or 2.
The meaning of the values of \fVrep\fR 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 \fVrep(1)\fR is 2, the frame definition must be given by
\fVrep1\fR. Otherwise, \fVrep1\fRcan be omitted.
\fVrep1\fR must be a row vector \fV[orx,ory,w,h]\fR giving respectively the coordinates of the upper-left point, the width and the height of the
plotting rectangle.
