Plot Area and Unit Setting Instructions

Instruction

IP - Input scaling point
IP [ P1 , P1 [,P2
X Y
P1 ; coordinate of P1
X X
P2 ; coordinate of P2
X X
The coordinate values used are absolute values in graphics units.
Sets the location of the scaling points(P1, P2).
Coordinate values for P1
The IP instruction is ignored when the set coordinates are outside the print area.
Using this instruction without a parameter field initializes the scaling points(P1, P2).
P2X and P2Y may be omitted. (If P2X and P2Y are omitted, P2 is set automatically so as not to alter the
distance between P1 and P2).
SC - Scale
SC Xmin, Xmax, Ymin, Ymax
Xmin ; X coordinate of P1
Ymin ; Y coordinate of P1
Sets the scale for the coordinates the user wants to establish.
Coordinate values for Xmin, Xmax, Ymin and Ymax are given as real numbers.
Using this instruction without a parameter field turns the scaling off.
The technical terms user unit and graphics unit as used in this manual are defined as follows;
