%SCALE Macro

Scales input coordinates relative to the origin (0, 0) based on the relationship between two ranges of minima and maxima.

Variables written out:	X, Y
Prerequisite:	You must run the %ANNOMAC macro before using any other annotate macros. For more information, see Making the Macros Available.

Syntax

%SCALE (ptx, pty, x1, y1, x2, y2, vx1, vy1, vx2, vy2);

ptx, pty: specifies the coordinates to scale. Values can be numbers, numeric constants, or numeric variables. For details, see the Annotate X Variable.
x1, y1: specifies the minima of the first range. Values can be numbers, numeric constants, or numeric variables.
x2, y2: specifies the maxima of the first range. Values can be numbers, numeric constants, or numeric variables.
vx1, vy1: specifies the minima of the second range. Values can be numbers, numeric constants, or numeric variables.
vx2, vy2: specifies the maxima of the second range. Values can be numbers, numeric constants, or numeric variables.

Details

The %SCALE macro reduces or enlarges Annotate graphics elements that use two-dimensional, numeric coordinates. The %SCALE macro does not affect graphics elements that are drawn with text functions.

The difference between the %SCALE and %SCALET macros is that the %SCALE macro always places the origin at (0, 0) and plots the new coordinates with respect to that origin. The %SCALET macro plots the new coordinates with respect to the minima of the second range. For details, see %SCALET Macro.

The following example uses the %SCALE macro to reduce x and y coordinates by 50 percent, as shown in Using the %SCALE Macro to Reduce the Size of a Box:

%SCALE(x, y, 0, 0, 100, 100, 0, 0, 50, 50);
