plot [ 3d ] [ item <id> ] [ { <range> } ] ( <filename> | { <expression> } | { <vector obj> } ) [ axes <axes>] [ every { <expression> } ] [ index <value>] [ select <expression> ] [ label <string expression> ] [ title <string> ] [ using { <expression> } ] [ with { <option> } ]
The plot command is used to produce graphs. The following simple example would plot the sine function:
plot sin(x)
Ranges for the axes of a graph can be specified by placing them in square brackets before the name of the function to be plotted. An example of this syntax would be:
plot [-pi:pi] sin(x)
which would plot the function (x)
-π
π
z
