Rectangles defined with the set object rectangle command can have individual styles. However, if a rectangle is not assigned a private style then it inherits a default that is taken from the set style rectangle command.
Syntax:
set style rectangle {front|back} {fillcolor <colorspec>} {fs <fillstyle>} {lw|linewidth <lw>}
See colorspec (p. ) and fillstyle (p. ). fillcolor may be abbreviated as fc.
Examples:
set style rectangle back fc rgb "white" fs solid 1.0 border -1 set style rectangle fc linsestyle 3 fs pattern 2 noborder
The default values correspond to solid fill with the background color and a black border.
