NAME

Chart::GGPlot::Plot - ggplot class

VERSION

version 0.0003

DESCRIPTION

This class represents the ggplot plot class. Instead of this class you would usually want to directly use Chart::GGPlot, which is a function interface of this library and is closer to R ggplot2's API.

ATTRIBUTES

backend

Consumer of Chart::GGPlot::Backend. Default is a Chart::GGPlot::Backend::Plotly object.

data

Data::Frame object.

mapping

Aesthetics mapping. Default is an empty Chart::GGPlot::Aes object.

METHODS

show

show(HashRef $opts={})

Show the plot (like in web browser). Implementation depends on the plotting backend.

save

save($filename, HashRef $opts={})

Export the plot to a static image file. Implementation depends on the plotting backend.

iplot

iplot(HashRef $opts={})

Generate plot for IPerl in Jupyter notebook. Implementation depends on the plotting backend.

summary

summary()

Get a useful description of a ggplot object.

theme

theme()

Returns theme of the plot.

add_layer

add_layer($layer)

Adds a Chart::GGPlot::Layer object to the plot.

You normally don't have to explicitly call this method.

add_labels

add_labels($labels)

Adds a Chart::GGPlot::Label object to the plot.

You normally don't have to explicitly call this method.

add_scale

add_scale($scale)

You normally don't have to explicitly call this method.

add_coord

add_coord($coord)

You normally don't have to explicitly call this method.

MORE METHODS

This class uses Perl's autoloading feature, to allow this class to get into its member methods exported functions of :ggplot tag from several other namespaces:

For example, when you do

$plot->geom_point(...)

It internally does something like,

my $layer = Chart::GGPlot::Geom::Functions::geom_point(...);
$plot->add_layer($layer);

Depend on the return type of the function it would call one of the class's add/set methods. In this case of geom_point() we get a layer object so add_layer() is called.
