    ZingChart Object and Methods

    Overview

    The ZingChart object contains properties to set global attributes such as general font face or size. The object also contains three important methods: the render method (zingchart.render()), which controls the rendering formats and characteristics to display the chart; the exec method (zingchart.exec()), which provides a mechanism to invoke various API calls on a chart; and the bind (zingchart.bind()) and unbind (zingchart.unbind()) methods, which listen for events that occur in the chart, and then do something with that event.

    ZingChart Object

    The ZingChart object contains the necessary properties and methods for chart rendering.

    Note: As of v2.9.0, we recommend using the LICENSE on the zingchart object with zingchart.LICENSE. This was previously set on the ZC.

    Attribute Type Info
    BUILDCODE Array

    Array of strings that denote our encrypted license keys.

    ['license_hash_key', 'zingchart.com']

    LICENSE Array

    Array of strings that denote our encrypted license keys.

    ['license_hash_key1', 'license_hash_key2']

    LICENSEKEY Array

    Array of strings that denote our encrypted license keys.

    ['license_hash_key1', 'license_hash_key2']

    ASYNC Boolean

    Renders the chart in "steps", providing faster (but incremental) visual results. This is useful in case of big charts that take longer time to render.

    true | false | 1 | 0
    bind Function

    Binds an event to a chart (or to all charts in a page).

    zingchart.bind("id", "eventName", function() {...})
    exec Function

    The API entry method, used to call various API commands against the chart.

    zingchart.exec("id", "call", {...})
    FONTFAMILY String

    Global setting for the font family used by all the elements of the library.

    "Arial" | "Helvetica" | ...
    FONTSIZE Numeric

    Global setting for the font size used by all the elements of the library.

    9 | 11 | ...
    MODULESDIR    
    unbind Function

    Unbinds an event from a chart (or from all charts in a page).

    zingchart.bind("id", "eventName", function() {...})
    ZCOUTPUT Boolean

    Sets whether an optional parameter called zcoutput, containing the rendering option, will be passed for every data request.

    true | false | 1 | 0
    SYNTAX String

    Sets whether the library converts input JSON syntax from camel case to dashed.

    dashed | mixed
    EXPORTURL String

    Sets the export URL for where the library will send ajax requests when exporting PDFs. If `AJAXEXPORT` is turned on, then images will also be rendered on the server, but currently images are rendered client side using Canvas and blobs.

    https://export.zingchart.com | https://customExportUrl.com
    AJAXEXPORT Boolean

    Sets whether the library uses the export server for all exports. Currently, the default is false since chart images are rendered on the client side using Canvas and blobs. Setting this to true will force a server export.

    false | true
    DEV Object

    Object that contains performance flags for various rendering paths within the ZingChart engine. DO NOT OVERRIDE THIS.

    {}

    DEV

    The zingchart.DEV object flags are for turning on and off rendering paths within the ZingChart rendering engine. These are globals, for all charts on the page, and MUST be defined before the zingchart.render() method.

    // prevents lib from storing the original data package
zingchart.DEV.KEEPSOURCE = false;
// prevents lib from creating a copy of the data package instead of working with the provided one (which can be altered) 
zingchart.DEV.COPYDATA = false; 

zingchart.render({...})
    Attribute Type Info
    CACHECANVASTEXT Boolean

    To use a cache object for storing text objects when rendering in Canvas. Default is false.

    true | false | 1 | 0
    CACHESELECTION Boolean

    To use a cache object for storing chart selected states. Default is false.

    true | false | 1 | 0
    CHECKDECIMALS Boolean

    Shortcut in rendering logic for checking decimals. If turned on, will be slower. Default is false.

    true | false | 1 | 0
    COPYDATA Boolean

    If set to false, prevents the library from creating a copy of the data package (object) instead of working with the provided one (which can be altered since it's passed by reference). Default is true.

    true | false | 1 | 0
    KEEPSOURCE Boolean

    If set to false, prevents the library from storing the original chart JSON data object. Default is true.

    true | false | 1 | 0
    MEDIARULES Boolean

    If set to false, prevents the library from looking down the chain of `mediaRule` objects defined through the chart configuration. Default is true.

    true | false | 1 | 0
    PLOTSTATS Boolean

    If set to false, skips calculations of several plot relates statistics (min, max, sum, avg values). Default is true.

    If set to false, skips setting event tracking on nodes. Default is true.

    true | false | 1 | 0
    SKIPPROGRESS Boolean

    If set to false, skips the intro loading screen. This loading screen is most likely invisible to human eye (< 222ms) on the average case. Default is false.

    true | false | 1 | 0
    SORTTOKENS Boolean

    If set to false, forces the library to accept only long tokes (e.g., %node-value instead of %v), saving some parsing time. Default is true.

    true | false | 1 | 0
    RESOURCES Boolean

    If set to false, indicates to the library that there are not external image resources to load. Skip this rendering path. Default is true.

    true | false | 1 | 0

    Render Method

    The ZingChart render method is used to set various chart render options. At a minimum, you must specify the id and data elements for the chart to properly render and display.

    zingchart.render({ 
  id: 'myChart', 
  data: { ... }, 
  height: 400, 
  width: 600

    ZC Object

    The ZC object contains various global information that we use internally for caching and code re-use. This object also contains some useful user information, like the version and license key.

    Note: As of v2.9.0, you can now use all licensing on the zingchart object with zingchart.LICENSE. This decision was made because the ES6 version was exporting two variables and the license was the only user functionality held in the ZC object.

    console.log(ZC.VERSION);
console.log(ZC.LICENSEKEY);
    Attribute Type Info
    BUILDCODE Array

    Array of strings that denote our encrypted license keys.

    ['license_hash_key', 'zingchart.com']

    LICENSE Array

    Array of strings that denote our encrypted license keys.

    `['license_hash_key1', 'license_hash_key2']`

    LICENSEKEY Array

    Array of strings that denote our encrypted license keys.

    `['license_hash_key1', 'license_hash_key2']`

    VERSION String

    The current version of the library.

    Summary

    The ZingChart object is essentially the runner of ZingChart, allowing you to set higher-level settings and render charts. For more information, see the ZingChart render method and ZingChart modules pages.
