ARCS Purpose
Plot specified arcs or circles on the current plot device.
Category
Calling Sequence
arcs, r, a1, a2, [x0, y0] Inputs
r = radii of arcs to draw (data units). in
[a1] = Start angle of arc (deg CCW from X axis, def=0). in
[a2] = End angle of arc (deg CCW from X axis, def=360). in
[x0, y0] = optional arc center (def=0,0). in
Keyword Parameters
Keywords
/DEVICE means use device coordinates .
/DATA means use data coordinates (default).
/NORM means use normalized coordinates.
/NOCLIP means do not clip arcs to the plot window.
COLOR=c plot color (scalar or array).
LINESTYLE=l linestyle (scalar or array).
THICKNESS=t line thickness (scalar or array).
XOUT=x, YOUT=y, PEN=p returned x,y, and pencode
of plotted radii. Can replot using plotp,x,y,p
/NOCLOSE Do not close the returned curve (x,y,p).
/NOPLOT do not plot the arcs.

Notes
Note: all parameters may be scalars or arrays.
