Inheritance hierarchy
This type inherits from BaseSettings.
Methods
Properties
Advanced chart settings. Be advised that they are subject to change, backwards compatibility is not guaranteed.
Chart area related settings.
The URL root where the ZoomCharts library and assets are located. For example, if the base.css file is available at 'http://server/css/zoomcharts/zc.css' then this value should be set to 'http://server/css/zoomcharts/'. Note that the library will try to determine its location automatically by searching the included script tags. So this property can be skipped if the assets folder is located next to 'zoomcharts.js' file on the server.
Element of the page where the chart will be inserted. Any HTML element should work, for example you can use a <div>.
Any contents of the element will be cleared - this behavior can be used to specify a loading message as the initial content,
for example <div>Chart is being initialized...</div>.
Note that a single element can host only one chart. If the same container is given to another chart, the previous chart will be automatically disposed.
Unless parentChart is specified, the value of the property is mandatory and can only be specified while creating the chart,
not with updateSettings. The value can be either an ID of an existing element or a reference to a DOM element.
Settings for displaying chart credits. Use it as a reference to additional data sources if necessery.
Note that even if credits enabled on page load, it's possible to hide on exported images.
Settings used to load data into chart. Customise preferred data source feeding methods. You can use one of these options: url, data function, preloaded data.
The events used to handle user interaction with UI elements.
Configurable conditions to filter the raw data values for subset of drawing slices.
Properties
Determines if zero values are automatically filtered from the data or if they will be displayed.
Note that if you want to show the empty values in the piechart, it might be useful to set
interaction.others.minSliceFraction to 0 or slice.minFraction to a value larger than 0.
Function to filter visible slices.
Parameters
slice filtering data
Return value
true to show the slice, false to hide the slice.
Slice icons as an additional element of style to highlight each individual slice or groups.
Properties
Whether to render icons if smaller than min value of sizeExtent.
Icon placement method
Valid values:- auto - maximize icon size
- center - always place in center of slice
Rising content field while hovering over slice. Content returned in a form of html and is relevant to context of slice hovered.
Properties
Prepare custom info popup contents. May return null and call callback(contents) later.
Parameters
slice data including subvalues
slice object to apply predefined content
Return value
Show/hide info popup.
Configurable interactivity options to navigate among the slices and pie levels to facilitate analysis of the grouped data in different ways.
Label settings related to internal and external slice text and their connectors.
The chart legend by additional interactivity to navigate between the slices or hilight each of them. Note that click on entries acts the same way as click on slice and is dependant of chart interaction mode.
Localizeable strings including export type options and useful default buttons used for chart interaction. Buttons like to navigate back, set the chart on full screen and others.
The parent chart within which the new chart will be rendered. If this property is specified, container cannot be

Center Y coordinate of the pie chart. If the value is 'null' - coordinate is calculated automatically. If the value is >1 - it specifies the exact x value in pixels. If the value is <=1 - it specifies a fraction of chart height.
