DonutChart

Builds a new chart with a label.

Sets any configuration option, with no checks for type / validity

This is more or less a bandaid to remove the handcuffs from users who want to add options that Google has added, that I have not. I didn't intend to restrict the user to only select options, as the goal was to type check and validate. This method can be used to set any option, just pass in arrays with key value pairs for any setting.

If the setting is an object, per the google docs, then use multi-dimensional arrays and they will be converted upon rendering.

This method will most likely be brought into 3.0 to prevent BC breaks, but I will incorporate the same functionality without the need for the extra customize() method call.

Sets configuration options from array of values

You can set the options all at once instead of passing them individually or chaining the functions from the chart objects.

Gets the current chart options.

Gets a specific option from the array.

Checks if any events have been assigned to the chart.

Checks if any events have been assigned to the chart.

Returns a JSON string representation of the datatable.

The background color for the main area of the chart. Can be either a simple HTML color string, for example: 'red' or '#00cc00', or a backgroundColor object

An object with members to configure the placement and size of the chart area (where the chart itself is drawn, excluding axis and legends).

Two formats are supported: a number, or a number followed by %. A simple number is a value in pixels; a number followed by % is a percentage.

The colors to use for the chart elements. An array of strings, where each element is an HTML color string, for example: colors:['red','#004411'].

Assigns wich Datatable will be used for this Chart.

If a label is provided then the defined Datatable will be used. If called with no argument, or the chart is attempted to be generated without calling this function, the chart will search for a Datatable with the same label as the Chart.

Set up the chart with no datatable to defer rendering via AJAX

Register javascript callbacks for specific events.

Valid values include: [ animationfinish | error | onmouseover | onmouseout | ready | select ] associated to a respective pre-defined javascript function as the callback.

The default font size, in pixels, of all text in the chart. You can override this using properties for specific chart elements.

The default font face for all text in the chart. You can override this using properties for specific chart elements.

Height of the chart, in pixels.

An object with members to configure various aspects of the legend. To specify properties of this object, create a new legend() object, set the values then pass it to this function or to the constructor.

Returns a JSON string representation of the chart's properties.

Outputs the chart javascript into the page

Pass in a string of the html elementID that you want the chart to be rendered into.

Text to display above the chart.

Where to place the chart title, compared to the chart area. Supported values: 'in' - Draw the title inside the chart area.

'out' - Draw the title outside the chart area. 'none' - Omit the title.

An object that specifies the title text style. create a new textStyle() object, set the values then pass it to this function or to the constructor.

An object with members to configure various tooltip elements. To specify properties of this object, create a new tooltip() object, set the values then pass it to this function or to the constructor.

Width of the chart, in pixels.

If set to true, displays a three-dimensional chart.

An array of slice objects, each describing the format of the corresponding slice in the pie. To use default values for a slice, specify a null. If a slice or a value is not specified, the global value will be used.

The values of the array keys will correspond to each numbered piece of the pie, starting from 0. You can skip slices by assigning the keys of the array as (int)s.

This would apply slice values to the first and fourth slice of the pie Example: array( 0 => new Slice(), 3 => new Slice() );

The color of the slice borders. Only applicable when the chart is two-dimensional; is3D == false || null

The content of the text displayed on the slice. Can be one of the following:

'percentage' - The percentage of the slice size out of the total. 'value' - The quantitative value of the slice. 'label' - The name of the slice. 'none' - No text is displayed.

An object that specifies the slice text style. create a new textStyle() object, set the values then pass it to this function or to the constructor.

The angle, in degrees, to rotate the chart by. The default of 0 will orient the leftmost edge of the first slice directly up.

If set to true, will draw slices counterclockwise. The default is to draw clockwise.

The slice relative part, below which a slice will not show individually.

All slices that have not passed this threshold will be combined to a single slice, whose size is the sum of all their sizes. Default is not to show individually any slice which is smaller than half a degree.

Color for the combination slice that holds all slices below sliceVisibilityThreshold.

A label for the combination slice that holds all slices below sliceVisibilityThreshold.

If between 0 and 1, displays a donut chart. The hole with have a radius equal to $pieHole times the radius of the chart.
