amcharts.getData

amcharts.getData(options: Object, callbackHandler: Function, updateHandler: Function)

Requests data from the component and preprocesses it to an array of objects. It is the format required by amCharts.

Parameters

Parameter/Type	Description
options Object	Allows setting options for data preprocessing.
options.slice SliceObject	optional Defines the data slice to be used for the chart. If not defined, the Connector prepares the data based on the current slice in Flexmonster Pivot. Note: if `amcharts.getData()` gets the slice as a parameter, the chart will not respond to further slice changes on the grid, which means data shown on the chart will be static.
options.prepareDataFunction Function	optional Allows you to override the Connector's default `prepareDataFunction` and perform custom data preprocessing if needed. If `prepareDataFunction` is not specified, the Connector uses the built-in method to preprocess the data. `prepareDataFunction` takes two input parameters: `rawData` – Object. Raw data to preprocess (check out the structure of `rawData` in getData()). `options` – Object. It contains options set in the `amcharts.getData()` function.
callbackHandler Function	Used to create the chart once the data is ready to be passed to it. Takes two input parameters: `chartData` – data preprocessed by either the Connector or `prepareDataFunction` (if it is defined). `rawData` – raw data from the component. It can be used to get the number formatting specified in Flexmonster. Check out the structure of rawData.
updateHandler Function	optional Used to update the chart when the report is updated. It takes the same input parameters as the callbackHandler function: `chartData` and `rawData`.

Returns

Returns an array of objects that contains the data for the chart. For example:

[
    {
        "categoryName": "value",
        "measureName 1": "value",
         …
        "measureName n": "value",
    }
    …
]

Example

Here is an example of passing the slice to the amcharts.getData() method:

flexmonster.amcharts.getData(
    {
        slice: {
            rows: [{uniqueName: "Country"}],
            columns: [{uniqueName: "[Measures]"}],
            measures: [{uniqueName: "Quantity"}]
        }
    }, 
    drawChart, 
    updateChart
);
