graph()graph(expression, setup)graph(t)graphmode(mode)Graph() solves the problem of obtaining multiple line plots during
a single run. During calls to graph(t), specified variables are stored
and plotted using scales determined by calls to axis().
graph() graph(s1, s2) axis(0,5,1,-1,1,2) axis()".
graph(t) graphmode(1) graph(t) after
a new setup statement is added to the list.
graphmode(-1) graph(t) will start new lines.
Should be executed just before a plt(-1) to ensure the entire lines
are plotted.
graphmode(2) graph(t) will continue the lines.
Graphs are normally flushed every 50 points.
proc p() { /* plot ramp */
axis(100,300,450,200)
axis(0,15,3,-1,1,2)
axis()
plot(1)
for (x=0; x<15; x=x+.1) {
plot(x, x/15) /* ramp */
graph(x) /* plots graph list if any */
}
graph(-1) /* flush remaining part of graphs, if any */
plt(-1)
}
p() /*plots the ramp alone*/
graph()
graph("sin(x)","axis(100,300,100,300) axis()")
graph("cos(x)","") /* same axes as previous call to graph */
p() /*plots the sin and cos along with the ramp*/
graph(s1, s2) is executed. The strings are
executed on calls to graph(t).
The best method for complicated plots is to make the setup string a simple call to a user defined procedure. This procedure can setup the axes, write the labels, etc. Newlines and strings within strings are possible by quoting with the `\verb+\+' character but generally are too confusing to be practical.
Local variables in graph strings make no sense.
