                                                  randomness => 5,
                                                  fill_color => 'purple',
                                                  label      => 'Candy totals',
                                                  text_size  => 12,

DESCRIPTION

Top

This class contains values to be charted as bars on a grid chart. The bars are filled with the specified color in the style of a child's crayon drawing.

ATTRIBUTES

Top

This class is a subclass of Chart::OFC::Dataset::OutlinedBar and accepts all of that class's attributes. It has one attribute of its own.

randomness

This is an integer (0 or greater) defining how random the sketch style is. The greater it is the more random the look. The default value is 3.

ROLES
