SYNOPSIS

Top

  my @numbers = ( [ 1, 2, 3 ], [ 3, 2, 1 ] );
  my $scatter =
      Chart::OFC::Dataset::Scatter->new
          ( values      => \@numbers,
            width       => 5,
            color       => 'purple',
            label       => 'Daily Sales in $',
            text_size   => 12,
            circle_size => 10,
          );

DESCRIPTION

Top

This class contains values to be charted as scatter points on a grid chart.

ATTRIBUTES

Top

This class has several attributes which may be passed to the new() method.

It is a subclass of Chart::OFC::Dataset::Line and accepts all of that class's attributes as well as its own.

values

This dataset accepts an arrayref which in turn contains one or more array references, each of which contains a set of values.

circle_size

This is included for compatibility with OFC, but does not seem to effect the chart.

Defaults to 5.

ROLES

Top

This class does the Chart::OFC::Role::OFCDataLines role.
