Call: PLOT_LINE

x

One of the 2 formats of the PLOT_LINE procedure call, takes a series of (x,y) coordinates as argument to describe the line which is to be drawn. Each of the x and y coordinates should be of the type Number.

There should be at least 2 pairs of (x,y) coordinates if you use this format.

The vector and scalar formats can not be mixed.

[These are mandatory arguments, no default is supplied.]

y

See x.

x_vector

One of the 2 formats of the PLOT_LINE procedure call, takes a pair of (x,y) coordinate vectors as argument. These vectors should both be a 1-dimensional Matrix. The vectors must have an equal length of at least 2.

The vector and scalar formats can not be mixed.

[These are mandatory arguments, no default is supplied.]

y_vector

See x_vector.

option

The option string is used to indicate which polyline representation is to be used, and also whether the line should be smoothened or not.

The following polyline representations can be used: SOLID, DASHED, DOTTED, DASH-DOTTED, FUNCTION-1, FUNCTION-2, FUNCTION-3, FUNCTION-4, FUNCTION-5, FUNCTION-6, FUNCTION-7, COMMENT, ERROR-BAR and BOX-TICKMARKS.

Use the REPRESENTATION graphics command to adjust the line width, the line type and the colour.

To obtain smoothened lines, add the option SMOOTH. Line smoothing is performed with cubic splines. Cubic splines tend to oscillate if there are jumps in the data points.

[Default: representation SOLID and no smoothing.]
