MORE INFORMATION

Data elements for RectangleChart can be given in the following forms:

	{x_i,y_i}	pure bar width and height
	w_i[{x_i,y_i},...]	a bar with size and wrapper
	form_i->m_i	a bar form with metadata

Data not given in these forms is ignored in forming the rectangle chart.

Datasets for RectangleChart can be given in the following forms:

	{e₁,e₂,...}	list of elements with or without wrappers
	w[{e₁,e₂,...},...]	wrapper applied to a whole dataset
	w[{data₁,data₁,...},...]	wrapper applied to all datasets

The following wrappers can be used for chart elements:

	Annotation[e,label]	provide an annotation
	Button[e,action]	define an action to execute when the element is clicked
	EventHandler[e,...]	define a general event handler for the element
	Hyperlink[e,uri]	make the element act as a hyperlink
	Labeled[e,...]	display the element with labeling
	Legended[e,...]	include features of the element in a chart legend
	Mouseover[e,over]	make the element show a mouseover form
	PopupWindow[e,cont]	attach a popup window to the element
	StatusArea[e,label]	display in the status area when the element is moused over
	Style[e,opts]	show the element using the specified styles
	Tooltip[e,label]	attach an arbitrary tooltip to the element

In RectangleChart, Labeled and Placed allow the following positions:

	Top,Bottom,Left,Right,Center	positions within bars
	Above,Below, Before, After	positions outside bars
	Axis	on the bar origin axis
	{{b_x,b_y},{l_x,l_y}}	scaled position in the label at scaled position in the bar

RectangleChart has the same options as Graphics with the following additions and changes:

AspectRatio	1/GoldenRatio	overall ratio of width to height
Axes	True	whether to draw axes
BarOrigin	Bottom	origin of bars
BarSpacing	Automatic	spacing between bars
ChartBaseStyle	Automatic	overall style for bars
ChartElements	Automatic	graphics to use for each of the bars
ChartElementFunction	Automatic	how to generate raw graphics for bars
ChartLabels	None	labels for data elements and datasets
ChartLayout	Automatic	overall layout to use
ChartLegends	None	legends for data elements and datasets
ChartStyle	Automatic	style for bars
ColorFunction	Automatic	how to color bars
ColorFunctionScaling	True	whether to normalize arguments to ColorFunction
LabelingFunction	Automatic	how to label bars
LegendAppearance	Automatic	overall appearance of legends
PerformanceGoal	$PerformanceGoal	aspects of performance to try to optimize

Possible settings for ChartLayout include and .

The arguments supplied to ChartElementFunction are the bar region , the data value , and metadata from each level in a nested list of datasets.

A list of built-in settings for ChartElementFunction can be obtained from .

The arguments supplied to ColorFunction consist of and .

Style and other specifications from options and other constructs in RectangleChart are effectively applied in the order ChartStyle, ColorFunction, Style and other wrappers, ChartElements, and ChartElementFunction, with later specifications overriding earlier ones.

Scope (26)

Items in a dataset are grouped together:

Datasets do not need to have the same number of items:

Non-real data is taken to be missing:

Use different layouts to display multiple datasets:

Control the origin of bars:

Adjust the spacing between bars and groups of bars:

Use wrappers on individual data, datasets, or collections of datasets:

Wrappers can be nested:

Override the default tooltips:

Use any object in the tooltip:

Use PopupWindow to provide additional drilldown information:

Button can be used to trigger any action:

Use an explicit list of styles for the bars:

Use any gradient or indexed color schemes from ColorData:

Use color schemes designed for charting:

ChartBaseStyle can be used to set an initial style for all chart elements:

Style can be used to override styles:

Use any graphic for pictorial bars:

Use built-in programmatically generated bars:

For detailed settings use Palettes ► ChartElementSchemes:

Use Labeled to add a label to a bar:

Use symbolic positions for label placement:

Provide categorical labels for the columns of data:

For rows of data:

For both:

Use Placed to control the positioning of labels, using the same positions as for Labeled:

Provide value labels for bars by using LabelingFunction:

Use Placed to control placement and formatting:

Add categorical legend entries for the columns of data:

For rows of data:

Use Legended to add additional legend entries:

Use Placed to affect the positioning of legends:

Options (60)

Change the bar origin:

Use automatically determined spacing between bars:

Use no spacing:

Use symbolic presets:

Use explicit spacing between bars:

Use explicit spacing between bars and groups of bars:

Use ChartBaseStyle to style all bars:

ChartBaseStyle combines with ChartStyle:

ChartStyle may override settings for ChartBaseStyle:

ChartBaseStyle combines with Style:

Style may override settings for ChartBaseStyle:

ChartBaseStyle combines with ColorFunction:

ColorFunction may override settings for ChartBaseStyle:

Create a pictorial chart based on any Graphics object:

Graphics3D:

Image:

Use a stretched version of the graphic:

Use explicit sizes for width and height:

Without AspectRatio->Full, the original aspect ratio is preserved:

Using All for width or height causes that direction to stretch to the full size of the bar:

Use a different graphic for each column of data:

Use a different graphic for each row of data:

Graphics are used cyclically:

Styles are inherited from styles set through ChartStyle etc:

Explicit styles set in the graphic will override other style settings:

The orientation of the pictorial graphic is unaffected by BarOrigin:

Create true 3D shaded bars:

Get a list of built-in settings for ChartElementFunction:

For detailed settings use Palettes ► ChartElementSchemes:

Here is a ChartElementFunction appropriate to show the global scale:

Write a custom ChartElementFunction:

Use metadata passed on from the input, in this case charting the data:

By default labels are placed in the axis:

Labeled wrappers in data will place additional labels:

Use Placed to control label placement:

Positions outside the bar:

Coordinate-based placement relative to a bar:

Place all labels at the upper-right corner and vary the coordinates within the label:

Use the third argument to Placed to control formatting:

Use a hyperlink label:

Rotate the labels:

By default labels are associated with columns of data:

Associate labels with rows or datasets:

Label both rows and columns:

Use Placed to affect placements:

Place multiple labels:

ChartLayout is grouped by default:

Use stepped bars:

Generate a legend based on chart style:

Use Legended to add additional legend entries:

Or to specify individual legend entries:

Generate a legend for datasets:

Unused legend labels are dropped:

Legends can be applied to several dimensions:

Use Placed to control the placement of legends:

Use ChartStyle to style bars:

Give a list of styles:

Use "Gradient" colors from ColorData:

Use "Indexed" colors from ColorData:

Styles are used cyclically:

Style each row of data:

Style both rows and columns of data:

With both row and column styles the last style may override earlier ones:

Style overrides settings for ChartStyle:

ColorFunction overrides settings for ChartStyle:

ChartElements with explicit style settings override settings for ChartStyle:

Color by bar height:

Use ColorFunctionScaling->False to get unscaled height values:

Color by area:

ColorFunction overrides styles in ChartStyle:

Use ColorFunction to combine different style effects:

Use ColorFunctionScaling->False to get unscaled height values:

Color by area:

Use automatic labeling by values through Tooltip and StatusArea:

Do no labeling:

Use Placed to control label placement:

Symbolic positions outside the bar:

Coordinate-based placement relative to a bar:

Control the formatting of labels:

Use the given chart labels as arguments to the labeling function:

Place complete labels as tooltips:

Generate a bar chart with interactive highlighting:

Emphasize performance by disabling interactive behaviors:

Typically less memory is required for non-interactive charts:
