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.
