LINE=<line type>,<thickness>,<line label>
(in PLOT operation for time series and scatter diagrams)
gives the line type used for connection of consecutive points.
<line type> can have values 0,1,2,3,4,5,6,7.
<thickness> (optional) is an integer. (See a note on the next page!)
<line label> (optional) is a string without spaces to be plotted at the
end of the time series (in the right margin). Default=no label.
Possible <line type> values and their interpretation when two
consecutive points (x1,y1) and (x2,y2) are connected.
0 move from (x1,y1) to (x2,y2) i.e. no visible line (default)
1 line from (x1,y1) to (x2,y2)
2 line from (x1,y1) to (x2,y1) and move from (x2,y1) to (x2,y2)
3 line from (x1,y1) to (x2,y1) and line from (x2,y1) to (x2,y2)
4 line from (x1,y1) to (x1,y2) and move from (x1,y2) to (x2,y2)
5 line from (x1,y1) to (x1,y2) and line from (x1,y2) to (x2,y2)
6 move from (x1,y1) to (x2,y2) and additional points
7 line from (x1,y1) to (x2,y2) and additional points
Alternatives 2,3,4 and 5 are for various step functions.
Alternatives 6 and 7 permit additional points to be plotted.
If <line type> is either 6 or 7, each point (x,y) in the diagram will
be connected to additional points given by LINE2, LINE3, ..., LINE6
specifications. LINE2 has the form
LINE2=<x2var>,<y2var>
where <x2var> and <y2var> are two variables (or constants) defining
the coordinates of an additional point. Other LINE specifications have
the same structure.
The point given by LINE2 can be labelled by a POINT2 specification of
the form POINT2=<marker_type>,<marker_size> (see POINT).
Points defined by LINE3, LINE4,... specifications may be labelled simi-
larly by POINT3, POINT4,...
The original syntax of LINE
LINE=<line type>,<thickness>,<line label>
should be preferred by
LINE=[line_width(thickness)],<line type>,1,<line label>
