ChartElementFunction

ChartElementFunction
is an option for charting functions such as BarChart that gives a function to use to generate the primitives for rendering each chart element.

MORE INFORMATION

ChartElementFunction->f specifies that each chart element should be rendered with the graphics primitives given by f[region, values, metadata].

ChartElementFunction->"name" uses a named function for generating chart elements.

Lists of built-in named functions for specific charting functions can be obtained from ChartElementData["BarChart"], etc.

In ChartElementFunction->f, the region argument to f is given as follows:

	BarChart,RectangleChart,Histogram,BubbleChart	{{x_min, x_max}, {y_min, y_max}}
	BarChart3D,RectangleChart3D,Histogram3D,BubbleChart3D	{{x_min, x_max}, {y_min, y_max}, {z_min, z_max}}
	PieChart,SectorChart	{{_min, _max}, {r_min, r_max}}
	PieChart3D, SectorChart3D	{{_min, _max}, {r_min, r_max}, {z_min, z_max}}

In ChartElementFunction->f, the values argument to f is given as follows:

	BarChart,BarChart3D,PieChart,PieChart3D	y
	RectangleChart,SectorChart	{x, y}
	RectangleChart3D, SectorChart3D,BubbleChart	{x, y, z}
	BubbleChart3D	{x, y, z, w}
	Histogram,Histogram3D	list

In the case of Histogram and Histogram3D the values given are those in the sublist of data associated with each bin.

With input data of form {d₁->m₁, d₂->m₂, ...} the metadata associated with d_i is {m_i}. With input data of the form {{d₁->m₁, d₂->m₂, ...}, ...}->m₀ the metadata associated with d_i is {m₀, m_i}.
