NAME lc - line-control mode
SYNOPSIS lc [0|1]
DESCRIPTION With line-control mode on, you can draw
multiply segmented lines from a single data set, or draw filled
shapes. Line-control information instructs the program whether
to move to a point with the pen up or down when drawing data with
one of the line symbols. (With graphics filters, it instructs
the filter whether to draw continuously or not.)
Line-control information is associated with each point. A
0 or nothing in the line-control column of a file
provides continuous drawing. A 1 instructs the
program to move to that point with the pen up. (The first point
is always reached with pen up.) A 2 means to fill
the connected points with the current "white" fill
color.
Entered without parameters, lc toggles the line-
control mode on and off. If the command is entered with a
0 as an argument, the line-control mode is turned
off. Entered with a 1, it is turned on.
Line-control information can be read using the get-data
command and is saved with the save-data command. Although a file
may include a column for line control, it will not be read in
unless the line-control mode has been turned on.
