SIZE Variable
Determines the size of the graphics element with
which it is used.
| Type: | numeric |
| Length: | 8 |
| Default: | 1.00 (2 when HSYS=3) |
| Interaction: | For the LABEL function, the value of the HTEXT= goption is used as the default. However, the value of the GUNIT= goption affects the default value that is used by the SIZE= variable. |
Syntax
SIZE=size-factor;
Variable Values
- size-factor
-
specifies the size of the graphics element. This variable is function dependent. See Functions.

About the SIZE Variable
The SIZE variable uses
the coordinate system that is specified by the HSYS Variable, which specifies the type of coordinate system used to generate
the graph.
As the thickness of
the line increases, it might be impossible to center around a given
coordinate. For example, if you specify a thickness of value 2 and
HSYS='4', the first line is drawn at the (X, Y) coordinates. The second
is drawn slightly above the first. The exact amount varies by device,
but it is always one pixel in width. A thickness of value 3 produces
one line above, one line at, and one line below the (X, Y) coordinate
position.
The SIZE variable is
equivalent to the HEIGHT= option in the SYMBOL statement. See SYMBOL Statement for details.
See Sample Line Thicknesses Used with the SIZE Variable for examples of line thicknesses.
