Graphics::Grid::Grob::Points - Points grob
version 0.0000_01
use Graphics::Grid::Grob::Points; use Graphics::Grid::GPar; my $points = Graphics::Grid::Grob::Points->new( x => [ map { rand() } (0 .. 9) ], y => [ map { rand() } (0 .. 9) ], pch => "A", gp => Graphics::Grid::GPar->new()); # or use the function interface use Graphics::Grid::Functions qw(:all); my $points = points_grob(%params);
This class represents a "points" graphical object.
A Grahpics::Grid::Unit object specifying x-values.
Default to an array ref of 10 numbers from rand().
rand()
A Grahpics::Grid::Unit object specifying y-values.
x and y combines to define the points. x and y shall have same length, which is the number of points in the grob object.
x
y
Plotting character. A single value to indicate what sort of plotting symbol to use. See points for the interpretation of these values.
Graphics::Grid::Unit object specifying the size of the plotting symbols. Default to unit(1, "char").
unit(1, "char")
A viewport object. When drawing a grob, if the grob has this attribute, the viewport would be temporily pushed onto the global viewport stack before drawing takes place, and be poped after drawing. If the grob does not have this attribute set, it would be drawn on the existing current viewport in the global viewport stack.
Get number of sub-elements in the grob.
Grob classes shall implement a _build_elems() method to support this attribute.
_build_elems()
For this module elems returns the number of points.
