This chapter describes how to draw graphs, using the @Code "@Graph"
graphs. @Index { graphs (statistical) }
graph. @Index @Code "@Graph"
symbol. For example,
@ID @OneRow @Code {
"@Graph"
" abovecaption { New South Wales road deaths, 1960--1990"
"(fatalities per 100 million vehicle km) }"
"{"
" @Data points { plus } pairs { dashed }"
" { 1963 5.6 1971 4.3 1976 3.7 1979 3.4 1982 2.9 1985 2.3 1988 2.0 }"
"}"
}
produces the graph
@CD @Graph
abovecaption { New South Wales road deaths, 1960--1990
(fatalities per 100 million vehicle km) }
{
@Data
points { plus }
pairs { dashed }
{
1963 5.6 1971 4.3 1976 3.7 1979 3.4 1982 2.9 1985 2.3 1988 2.0
}
}
The features of @Code "@Graph" include captions, automatic and manual
ticks and labels, logarithmic axes, histograms, and plotting of
mathematical functions.
