FusionCharts JavaScript API - Events

FusionCharts JavaScript Class API provides a number of events. Events are categorized into two broad groups - Simple Events and Advanced events. Each event provides arguments to the event-listeners. In simple event, most of events (except for FC_Exported and FC_Resized events) provides DOMId of the source chart that raised the event.  In advanced model, two event parameters are passed to the event listener function. The first parameter, eventObject, is structurally common for all events. The second parameter, argumentsObject contains event specific properties. Details of eventObject are given as follows:

Event parameters in advanced model

Each event sends parameters to event listener functions. In advanced event model, two event argument Objects are sent to event listener. The properties contained by the arguments are as follows:

  • The first argument is eventObject which provides details of the event. It is an object which provides three properties :
    • eventId : An unique ID given to the event
    • eventType : A String containing the name or the event type, for example, "rendered" etc.
    • sender : A FusionCharts JavaScript Object reference to the chart which has raised that event
  • The second argument argumentsObject is an Object which contains details of the particular event fired. As per the type of the event the properties of parameter objects varies.

The list shown below contains names of events of both Simple and Advanced events. Moreover, details of argumentsObject for each event is listed down.

Name (Advanced model) Name ( Simple model) What is it and when is it raised? Event parameters
