NAME

Chart::GGPlot::Geom::Functions - Function interface for Chart::GGPlot::Geom

VERSION

version 0.0002_01

DESCRIPTION

This module provides the geom_* functions supported by this Chart-GGPlot library. When used standalone, each geom_* function generates a Chart::GGPlot::Layer object. Also the functions can be used as Chart::GGPlot::Plot methods, to add layers into the plot object.

FUNCTIONS

geom_path

geom_path(:$mapping = undef, :$data = undef, :$stat = 'identity',
    :$position = 'identity', :$na_rm = false, :$show_legend = 'auto',
    :$inherit_aes = true, 
    %rest)

The "path" geom connects the observations in the order in which they appear in the data.

geom_line

geom_line(:$mapping = undef, :$data = undef, :$stat = 'identity',
    :$position = 'identity', :$na_rm = false, :$show_legend = 'auto',           :$inherit_aes = true, 
    %rest)

The "line" geom connects the observations in the order of the variable on the x axis.

geom_point

geom_point(:$mapping = undef, :$data = undef, :$stat = 'identity',
    :$position = 'identity', :$na_rm = false, :$show_legend = 'auto',
    :$inherit_aes = true, %rest)

The "point" geom is used to create scatterplots. The scatterplot is most useful for displaying the relationship between two continuous variables. A bubblechart is a scatterplot with a third variable mapped to the size of points.

geom_bar

geom_bar(:$mapping = undef, :$data = undef, :$stat = 'count',
    :$position = 'stack', :$width = undef,
    :$na_rm = false, :$show_legend = 'auto', :$inherit_aes = true,
    %rest)

The "bar" geom makes the height bar proportional to the number of cases in each group (or if the weight aesthetic is supplied, the sum of the weights). It uses stat_count() by default: it counts the number of cases at each x position.

geom_histogram

geom_histogram(:$data = undef, :$mapping = undef, :$stat = "bin",
    :$position = "stack", :$binwidth = undef, :$bins = undef,
    :$na_rm = false, :$show_legend = 'auto', :$inherit_aes = true,
    %rest)

Visualise the distribution of a single continuous variable by dividing the x axis into bins and counting the number of observations in each bin. This "histogram" geom displays the counts with bars.
