70.54 Object
This command defines a single object, which will appear in all subsequent 2D plots. You may define
as many objects as you like. Currently the only object type supported is rectangle. Each rectangle is
specified by a pair of points that define diagonal vertices. A default set of style properties (fill, color,
border) are inherited from those set by the command set style rectangle, but each rectangle can also
be given individual style properties.
Syntax:
set object rectangle
{from {to|rto} |
center size , |
at size ,}
{front|back|behind} {fc|fillcolor } {fs }
{default} {lw|linewidth }
The position of the rectangle may be specified by giving the position of two diagonal corners (bottom
left and top right) or by giving the position of the center followed by the width and the height. In either
case the positions may be given in axis, graph, or screen coordinates. See coordinates (p. 24). The
options at and center are synonyms.
Setting front will draw the rectangle in front of all plot elements, but behind any labels that are also
marked front. Setting back will place the rectangle behind all plot curves and labels. Setting behind
will place the rectangle behind everything including the axes and back rectangles, and can be used to
provide a colored background for the entire graph or page.
The fill color of the rectangle is taken from the . fillcolor may be abbreviated fc. The fill
style is taken from . See colorspec (p. 32) and fillstyle (p. 131). If the keyword default
is given, these properties are inherited from the default settings of at the time a plot is drawn. See set
style rectangle (p. 134).
Examples:
# Force the entire area enclosed by the axes to have background color cyan
set object 1 rect from graph 0, graph 0 to graph 1, graph 1 back
set object 1 rect fc rgb "cyan" fillstyle solid 1.0
# Position a red square with lower left at 0,0 and upper right at 2,3
set object 2 rect from 0,0 to 2,3 fc lt 1
# Position an empty rectangle (no fill) with a blue border
set object 3 rect from 0,0 to 2,3 fs empty border 3
# Return fill and color to the default style but leave vertices unchanged
set object 2 rect default
70.55 Rmargin
The command set rmargin sets the size of the right margin. Please see set margin (p. 112) for
details.
70.56 Rrange
The set rrange command sets the range of the radial coordinate for a graph in polar mode. Please see
set xrange (p. 142) for details.
