NAME
Chart::GGPlot::Layer - Chart::GGPlot layer
VERSION
version 0.002003
DESCRIPTION
A layer is a combination of data, stat and geom with a potential position adjustment. Usually layers are created using geom_* or stat_* calls but it can also be created directly using this class.
ATTRIBUTES
data
The data to be displayed in this layer. If undef, the default, the data is inherited from the plot data as specified in the call to ggplot().
mapping
Set of aesthetic mappings created by aes(). If specified and inherit_aes is true (the default), it's combined with the default mapping at the top level of the plot. You must supply this attribute if there no plot mapping.
geom
The geometric object to use display the data.
stat
The statistical transformation to use on the data for this layer, as a string.
position
Position adjustment, either as a string, or the result of a call to a position adjust function.
inherit_aes
If false, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification.
params
Additional parameters to the "geom" and "stat".
show_legend
Should this layer be included in the legends?
undef, includes if any aesthetics are mapped.A defined true scalar (non-Chart::GGPlot::Aes), never includes.
A defined false scalar (non-Chart::GGPlot::Aes), always includes.
A Chart::GGPlot::Aes object whose values are booleans, to finely
select the aesthetics to display.
METHODS
string()
