Chart::GGPlot::Stat::Functions - Function interface for stats
version 0.0007
stat_bin(:$mapping=undef, :$data=undef, :$geom="bar", :$position="stack", :$binwidth=undef, :$bins=undef, :$center=undef, :$boundary=undef, :$breaks=undef, :$pad=false, :$na_rm=false, :$show_legend='auto', :$inherit_aes=true, %rest)
Arguments:
$mapping
Set of aesthetic mappings created by aes(). If specified and $inherit_aes is true (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.
aes()
$inherit_aes
$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().
undef
ggplot()
$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 adjustment function.
$na_rm
If false, the default, missing values are removed with a warning. If true, missing values are silently removed.
$show_legend
Should this layer be included in the legends? undef, the default, includes if any aesthetics are mapped. A true scalar for never includes, and a defined false scalar for always includes.
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.
%rest
Other arguments passed to Chart::GGPlot::Layer->new(). These are often aesthetics, used to set an aesthetic to a fixed value, like color => "red", size => 3. They may also be parameters to the paired geom/stat.
Chart::GGPlot::Layer->new()
color => "red", size => 3
$binwidth
The width of the bins. Can be specified as a numeric value, or a function that calculates width from x. The default is to use $bins bins that cover the range of the data.
$bins
Number of bins. Overridden by $binwidth. Defaults to 30.
You should always override this $bins or $binwidth, exploring multiple widths to find the best to illustrate the stories in your data.
stat_boxplot(:$mapping=undef, :$data=undef, :$geom='boxplot', :$position='dodge2', :$coef=1.5, :$na_rm=false, :$show_legend='auto', :$inherit_aes=true, %rest)
$coef
Length of the whiskers as multiple of IQR. Defaults to 1.5.
stat_count(:$mapping=undef, :$data=undef, :$geom='bar', :$position='stack', :$width=undef, :$na_rm=false, :$show_legend=undef, :$inherit_aes=true, %rest)
$width
Bar width. By default, set to 90% of the resolution of the data.
stat_identity(:$mapping=undef, :$data=undef, :$geom="point", :$position="identity", :$show_legend=undef, :$inherit_aes=true, %rest)
stat_smooth(:$maping=undef, :$data=undef, :$geom='smooth', :$position='identity', :$method='auto', :$se=true, :$n=80, :$span=0.75, :$fullrange=false, :$level=0.95, :$method_args={}, :$na_rm=false, :$show_legend='auto', :$inherit_aes=true, %rest)
method
Smoothing method (function) to use.
The available methods are,
'auto'
'loess' is used for less than 1000 observations, 'glm' otherwise
'loess'
Locally Weighted Regression
Requires Math::LOESS.
Supported $method_args, (see Math::LOESS::Model for details)
$method_args
$degree
$parametric
$drop_square
$normalize
$family
'glm' : Generalized Linear Model
Requires PDL::Stats::GLM and PDL::GSL::CDF.
At this moment we can do only simple linear modeling. Still to support logistic and polynomial in future.
Supported $method_args,
method_args
Additional optional arguments passed on to the modeling function defined by $method.
$method
se
Display confidence interval around smooth? (true by default, see $level to control.)
$level
fullrange
Should the fit span the full range of the plot, or just the data?
level
Level of confidence interval to use (0.95 by default). Effective when $se is true.
$se
span
Controls the amount of smoothing for the default loess smoother. Larger number means more smoothing. It should be in the (0, 1) range.
(0, 1)
n
Number of points at which to evaluate smoother.
