Scilab function

plot_graph - general plot of a graph

Calling Sequence

plot_graph(g,[rep,rep1])

Parameters

• g : graph list
• rep : row vector of 13 values for the parameters of the plot
• rep1 : row vector of 4 values defining the plotting rectangle

Description

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.

Examples

```// simple graph with different choices for the plot
ta=[2 2 1 1 2 4 3 3 4];
he=[2 2 3 2 3 2 1 2 1];
g=make_graph('foo',1,4,ta,he);
g('node_type')=[1 1 1 2];g('node_name')=string([1:4]);
g('node_x')=[73 737 381 391]; g('node_y')=[283 337 458 142];
g('node_color')=[3 3 3 11];
g('node_diam')=[30 30 30 60];
g('edge_color')=[10 0 2 6 11 11 0 0 11];
rep=[2 2 1 1 2 2 2 2 2 2 2 2 2];
rep1=[100 -400 650 300];
xbasc(); plot_graph(g,rep,rep1);
rep=[2 1 1 1 2 2 2 2 2 2 2 2 2];
x_message('plot the graph with different parameters');
xbasc(); plot_graph(g,rep,rep1);
// plotting using dialogs
xbasc(); plot_graph(g);
xset("thickness",4);
xbasc();
plot_graph(g);
xset('default');
