Set the center of the graphic range to the center of the screen. If the
drawing range in the program can be contained in the above actual
graphics range, set the magnification to 1 (actual value set is 100).
When the drawing range is larger than the maximum graphics range or
much smaller than the maximum graphics range, the graphics
magnification should be changed. The graphics magnification is 0.01 to
100.00 times, which is usually determined as follows;
Graphics magnification=Graphics magnification (
H), or graphics
magnifications (
V), whichever is smaller
Graphics magnification
H =α/(length on program to horizontal
direction axis)
Graphics magnification
V=β/(length on program to vertical
direction axis)
