EXPLANATION
This Command draws a smooth curve connecting a set of relative coordinates in the sequence
(dx1,dy1) (dx2,dy 2 ) (dxn,dyn). The specification of the m parameter (0 to 1) deter-
mines whether the curve will be open or closed, as shown in the figure below.
Note: The drawing of a closed curved line begins from the second specified coordinate pair.
Open curve m = 1
Closed curve m = 1
Fig. -1
The m parameter may be either 0 or 1, and decimal fractions are ignored. Coordinate
parameters that can be expressed relatively must be in the range of - 32768.0000 to
+ 32767.4999 on the X to Y axes to be valid, and decimal fractions ate rounded up or down to
the nearest integer.
Please note the following when using this command.
(1) Failure to specify at least 3 pairs of coordinates will result in an error.
(2) Avoid specifying points with the same, or extremely close, coordinates.
(3) Avoid specifying points whose coordinate pairs are widely separated from each other.
(4) Be careful when specifying coordinates that fall on or close to the boundary of the plotting
area. Any parts of the curve that extend beyond the plotting area will not be drawn.
(5) As shown below, specifying a parameter that returns to the same coordinate position in a
previous parameter will cause an error.
