# This is plot processes for tkemc popup under the view menu

# pixels less scrollbars.  The full canvas could be much larger.
# Several local variables may be set below to match machines.

# These offset plot zero from canvas zero.
set xoffset 0
set yoffset 0
set zoffset 0

# These set the axis directions.  +1 one plots like graph
# paper with positive up and to the right.  The canvas widgets orient so that
# xy plot is looking down on the work area from the operator position.
# x is left right and y is up down.
# xz plot is looking into the work area along the axis of y
# yz plot is looking into the work area along the axis of x
# to reverse as axis change its value to -1 (don't put other numbers here)
set xdir 1
set ydir 1
set zdir 1

# These set the size of the canvas widget behind the viewing area.
# Set for the size of your machine or larger.  They can also be set so that you
# place your machine home about the same location in canvas space that it has on the
# real machine.
# They need not be the same for each axis.
# the value used is pixels so multiply your machine workspace size in inches by 72.

# the default shipped here is for a center zero'd machine with 1000 pixels both left/right
# and 500 pixels both top/bottom in all axis.
# Read variable names (xytopx) as "xy plot topleft x" value etc.

# If your machine were top right homed on xy, you might use
#   xy -1900 -100 100 900
#   xz -1900 -100 100 900
#   yz -100 -100 1900 900

# These set top left and bottom right of xy canvas
set xytopx -1000
set xytopy -500
set xybotx 1000
set xyboty 500

# These set top left and bottom right of xz canvas
set xztopx -1000

# These set top left and bottom right of yz canvas

# This variable sets the default size of the plot and can be thought of as number of
# pixels per inch of machine motion.  The default (40) will give about .55 screen
# inch per inch moved.
