NAME

Chart::GGPlot::Aes - Aesthetic mappings

VERSION

version 0.0005

DESCRIPTION

This class inherits Chart::GGPlot::Params to accept various names of same concept, like color/colour/fg, fill/bg, etc. Unlike Chart::GGPlot::Params, this class has its object keys alphabetically sorted.

It is designed for holding aesthetics-specific data. It can usually be used in either of below two ways:

  • Created by the aes() function.

    For specifying how the aesthetics, like x/y variables (column names), colors, etc., are mapped to data in your data frame input to ggplot().

  • Used only for its key alias feature.

    See Chart::GGPlot::Labels.

CLASS METHODS

check_aesthetics

    check_aesthetics($aes, $n=undef)

Checks if all values in the $aes object are of length $n or 1. Dies on check failure. $aes can be either a Chart::GGPlot::Aes object or a data frame object. If $n is not specified, it defaults to the max length of values (or columns) of $aes.

METHODS

string

    string()
