**[G-4]** *relativesize* -- Choices for sizes of objects

__Syntax__

*relativesize* Description
-------------------------------------------------------------------------
*#* specify size; size 100 = minimum of width and
height of graph; *#* must be >= 0, depending on
context

******#* specify size change via multiplication; ***1** means no
change, ***2** twice as large, ***.5** half; *#* must be >=
0, depending on context
-------------------------------------------------------------------------
Negative sizes are allowed in certain contexts, such as for gaps; in
other cases, such as the size of symbol, the size must be nonnegative,
and negative sizes, if specified, are ignored.

Examples:

*example* Description
-------------------------------------------------------------------------
**msize(2)** make marker diameter 2% of *g*
**msize(1.5)** make marker diameter 1.5% of *g*
**msize(.5)** make marker diameter .5% of *g*
**msize(*2)** make marker size twice as large as default
**msize(*1.5)** make marker size 1.5 times as large as default
**msize(*.5)** make marker size half as large as default

**xsca(titlegap(2))** make gap 2% of *g*
**xsca(titlegap(.5))** make gap .5% of *g*
**xsca(titlegap(-2))** make gap -2% of *g*
**xsca(titlegap(-.5))** make gap -.5% of *g*
**xsca(titlegap(*2))** make gap twice as large as default
**xsca(titlegap(*.5))** make gap half as large as default
**xsca(titlegap(*-2))** make gap -2 times as large as default
**xsca(titlegap(*-.5))** make gap -.5 times as large as default
-------------------------------------------------------------------------
where *g* = min(width of graph, height of graph)

__Description__

A *relativesize* specifies a size relative to the graph (or subgraph) being
drawn. Thus as the size of the graph changes, so does the size of the
object.

__Remarks__

*relativesize* is allowed, for instance, as a *textsizestyle* or a
*markersizestyle* -- see **[G-4]** *textsizestyle* and **[G-4]** *markersizestyle* --
and as the size of many other things, as well.

Relative sizes are not restricted to being integers; relative sizes of
.5, 1.25, 15.1, etc., are allowed.
