+The getter forms of functions do not participate in function chaining because they necessarily

+#### .xUnits([xUnits function])
+Set or get the xUnits function. The coordinate grid chart uses the xUnits function to calculate
+the number of data projections on x axis such as the number of bars for a bar chart or the
+number of dots for a line chart. This function is expected to return a Javascript array of all
+data points on x axis, or the number of points on the axis. [d3 time range functions
+d3.time.days, d3.time.months, and
+d3.time.years](https://github.com/mbostock/d3/wiki/Time-Intervals#aliases) are all valid xUnits
+function. dc.js also provides a few units function, see the [Utilities](#utilities) section for
+a list of built-in units functions. The default xUnits function is dc.units.integers.
+```js
+// set x units to count days
+chart.xUnits(d3.time.days);
+// set x units to count months
+chart.xUnits(d3.time.months);
+```
+A custom xUnits function can be used as long as it follows the following interface:
+```js
+// units in integer
+function(start, end, xDomain) {
+// simply calculates how many integers in the domain
+return Math.abs(end - start);
+};
+// fixed units
+function(start, end, xDomain) {
+// be aware using fixed units will disable the focus/zoom ability on the chart

+Interaction with a chart will only trigger events and redraws within the chart's group.

+/**
+#### .columns([columnFunctionArray])
+Get or set column functions. The data table widget now supports several methods of specifying
+the columns to display.  The original method, first shown below, uses an array of functions to
+generate dynamic columns. Column functions are simple javascript functions with only one input
+argument `d` which represents a row in the data set. The return value of these functions will be
+used directly to generate table content for each cell. However, this method requires the .html
+table entry to have a fixed set of column headers.
+```js
+chart.columns([
+function(d) {
+return d.date;
+},
+function(d) {
+return d.open;
+},
+function(d) {
+return d.close;
+},
+function(d) {
+return numberFormat(d.close - d.open);
+},
+function(d) {
+return d.volume;
+}
+]);
+```
+The next example shows you can simply list the data (d) content directly without
+specifying it as a function, except where necessary (ie, computed columns).  Note
+the data element accessor name is capitalized when displayed in the table. You can
+also mix in functions as desired or necessary, but you must use the
+Object = [Label, Fn] method as shown below.
+You may wish to override the following two functions, which are internally used to
+translate the column information or function into a displayed header. The first one
+is used on the simple "string" column specifier, the second is used to transform the
+String(fn) into something displayable. For the Stock example, the function for Change
+becomes a header of 'd.close - d.open'.
+_chart._doColumnHeaderCapitalize _chart._doColumnHeaderFnToString
+You may use your own Object definition, however you must then override
+_chart._doColumnHeaderFormat , _chart._doColumnValueFormat
+Be aware that fields without numberFormat specification will be displayed just as
+they are stored in the data, unformatted.
+```js
+chart.columns([
+"date",    // d["date"], ie, a field accessor; capitalized automatically
+"open",    // ...
+"close",   // ...
+["Change", // Specify an Object = [Label, Fn]
+function (d) {
+return numberFormat(d.close - d.open);
+}],
+"volume"   // d["volume"], ie, a field accessor; capitalized automatically
+]);
+```
+A third example, where all fields are specified using the Object = [Label, Fn] method.
+```js
+chart.columns([
+["Date",   // Specify an Object = [Label, Fn]
+function (d) {
+return d.date;
+}],
+["Open",
+function (d) {
+return numberFormat(d.open);
+}],
+["Close",
+function (d) {
+return numberFormat(d.close);
+}],
+["Change",
+function (d) {
+return numberFormat(d.close - d.open);
+}],
+["Volume",

+## Composite Chart
+Includes: [Coordinate Grid Mixin](#coordinate-grid-mixin)
+Composite charts are a special kind of chart that render multiple charts on the same Coordinate
+Grid. You can overlay (compose) different bar/line/area charts in a single composite chart to
+achieve some quite flexible charting effects.
+#### dc.compositeChart(parent[, chartGroup])
+Create a composite chart instance and attach it to the given parent element.
+Parameters:
+* parent : string | node | selection - any valid
+[d3 single selector](https://github.com/mbostock/d3/wiki/Selections#selecting-elements) specifying
+a dom block element such as a div; or a dom element or d3 selection.
+* chartGroup : string (optional) - name of the chart group this chart instance should be placed in.
+Interaction with a chart will only trigger events and redraws within the chart's group.
+Returns:
+A newly created composite chart instance
+```js
+// create a composite chart under #chart-container1 element using the default global chart group
+var compositeChart1 = dc.compositeChart('#chart-container1');
+// create a composite chart under #chart-container2 element using chart group A

+## Bubble Overlay Chart
+Includes: [Bubble Mixin](#bubble-mixin), [Base Mixin](#base-mixin)
+The bubble overlay chart is quite different from the typical bubble chart. With the bubble overlay
+chart you can arbitrarily place bubbles on an existing svg or bitmap image, thus changing the
+typical x and y positioning while retaining the capability to visualize data using bubble radius
+and coloring.
+Examples:
+* [Canadian City Crime Stats](http://dc-js.github.com/dc.js/crime/index.html)
+#### dc.bubbleOverlay(parent[, chartGroup])
+Create a bubble overlay chart instance and attach it to the given parent element.
+Parameters:
+* parent : string | node | selection - any valid
+[d3 single selector](https://github.com/mbostock/d3/wiki/Selections#selecting-elements) specifying
+a dom block element such as a div; or a dom element or d3 selection.
+off-screen. Typically this element should also be the parent of the underlying image.
+* chartGroup : string (optional) - name of the chart group this chart instance should be placed in.
+Interaction with a chart will only trigger events and redraws within the chart's group.
+Returns:
+A newly created bubble overlay chart instance
+```js
+// create a bubble overlay chart on top of the '#chart-container1 svg' element using the default global chart group
+var bubbleChart1 = dc.bubbleOverlayChart('#chart-container1').svg(d3.select('#chart-container1 svg'));
+// create a bubble overlay chart on top of the '#chart-container2 svg' element using chart group A
+var bubbleChart2 = dc.compositeChart('#chart-container2', 'chartGroupA').svg(d3.select('#chart-container2 svg'));
+```
+#### .svg(imageElement) - **mandatory**
+Set the underlying svg image element. Unlike other dc charts this chart will not generate a svg
+element; therefore the bubble overlay chart will not work if this function is not invoked. If the
+underlying image is a bitmap, then an empty svg will need to be created on top of the image.

+Create a Number Display instance and attach it to the given parent element.

+* chartGroup : string (optional) - name of the chart group this chart instance should be placed in.
+The number display widget will only react to filter changes in the chart group.

+## Box Plot
+Includes: [Coordinate Grid Mixin](#coordinate-grid-mixin)
+A box plot is a chart that depicts numerical data via their quartile ranges.
+#### dc.boxPlot(parent[, chartGroup])
+Create a box plot instance and attach it to the given parent element.
+Parameters:
+* parent : string | node | selection - any valid
+[d3 single selector](https://github.com/mbostock/d3/wiki/Selections#selecting-elements) representing
+a dom block element such as a div; or a dom element or d3 selection.
+* chartGroup : string (optional) - name of the chart group this chart instance should be placed in.
+Interaction with a chart will only trigger events and redraws within the chart's group.
+Returns:
+A newly created box plot instance
+```js
+// create a box plot under #chart-container1 element using the default global chart group
+var boxPlot1 = dc.boxPlot('#chart-container1');
+// create a box plot under #chart-container2 element using chart group A
