    This tutorial will help you integrate Flexmonster with the Highcharts charting library.

    Watch the tutorial in the video format: Pivot table with Highcharts.

    Supported chart types

    Flexmonster supports the following Highchart types:

    If the chart type that you want to use is not on the list, it is possible to use prepareDataFunction to preprocess the data to fit your preferences.

    More ready-to-use examples of integration with Highcharts you can find on the Examples page.

    Adding Highcharts

    Step 1. Add the component using data from a CSV file to your HTML page. Replace XXXX-XXXX-XXXX-XXXX-XXXX with your license key. If you don't have a license key, contact our team and request a special trial key.

    <div id="pivotContainer">The component will appear here</div>
    <script src="https://cdn.flexmonster.com/flexmonster.js"></script>
    
    <script>
      var pivot = new Flexmonster({ 
        container: "pivotContainer",
        componentFolder: "https://cdn.flexmonster.com/",
        toolbar: true,
        report: {
          dataSource: {
            filename: "data/data.csv"
          },
          slice: {
            rows: [
              { uniqueName: "Country" }
            ],
            columns: [
              { uniqueName: "Business Type" },
              { uniqueName: "[Measures]" } 
            ],
            measures: [
              { uniqueName: "Price" }
            ]
          }
        },
        licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
      });
    </script>

    Step 2. Add Highcharts:

    <script src="https://code.highcharts.com/highcharts.js"></script>

    Step 3. Add our connector for Highcharts:

    <script src="https://cdn.flexmonster.com/lib/flexmonster.highcharts.js"></script>

    Step 4. Add a container for the chart:

    <div id="chartContainer"></div>

    Step 5. Add a reportComplete event handler to know when the pivot table is ready to be a data provider:

    reportcomplete: function() {
      pivot.off("reportcomplete");
      createChart();
    } 

    Step 6. Add a function to create the chart. This function uses the connector for Highcharts from flexmonster.highcharts.js. The connector extends the Flexmonster API with the following call: highcharts.getData(options, callbackHandler, updateHandler).

    function createChart() {
      pivot.highcharts.getData(
        {},
        function(chartConfig) {
          Highcharts.chart("chartContainer", chartConfig);
        },  
        function(chartConfig) {
          Highcharts.chart("chartContainer", chartConfig);
        }
      );
    } 

    You will see a line chart that displays the same data that is shown in the pivot pivot table instance and it will react to updates. Check out a live example on JSFiddle.

    You can also watch our video tutorial that covers the integration process:

    Flexmonster Connector for Highcharts

    flexmonster.highcharts.js is a connector between our component and Highcharts. The highcharts.getData() method requests data from the pivot table and preprocesses it to the appropriate format for the required type of chart.

    highcharts.getData(options:Object, callbackHandler:Function, updateHandler:Function) has the following parameters:

    Parameter/TypeDescription
    options
    Object
    Allows setting options for data preprocessing.
    options.type
    String
    optional The chart type to prepare data for.
    Default value: "line".
    Here is an example of how to specify a chart type:
    function pie() {
    pivot.highcharts.getData(
    {
    type: "pie"
    },
    function(chartConfig) {
    Highcharts.chart("chartContainer", chartConfig);
    },
    function(chartConfig) {
    Highcharts.chart("chartContainer", chartConfig);
    }
    );
    }
    options.slice
    SliceObject
    optional Defines the slice from which the data should be returned (for JSON and CSV data sources only). If not defined, the API call will return data currently displayed in the pivot table.
    Here is an example of a slice:
    function withManyYAxis() {
    pivot.highcharts.getData(
    {
    type: "column",
    slice: {
    rows: [{uniqueName: "Country"}],
    columns: [{uniqueName: "[Measures]"}],
    measures: [
    {uniqueName: "Price"},
    {uniqueName: "Quantity"}
    ]
    }
    },
    function(chartConfig) {
    Highcharts.chart("chartContainer", chartConfig);
    },
    function(chartConfig) {
    Highcharts.chart("chartContainer", chartConfig);
    }
    );
    }
    options.xAxisType
    String
    optional Set the value of this to "datetime" to use dates on the X-axis. Try it on JSFiddle, this sample also illustrates how to define a type for particular series.
    options.valuesOnly
    Boolean
    optional Set this property to true to display all axes values in the chart as numbers. This property is applicable only for the following chart types: "bubble", "line", "polygon", and "spline". Note, that this value is always true for the "scatter" chart (and you do not need to set it explicitly to true). Try it on JSFiddle.
    Default value: false.
    options.withDrilldown
    Boolean
    optional Set this property to true to have drill-downs in the chart. This property is available for the following chart types: "area", "areaspline", "bar", "column", "waterfall", "funnel", "pie", "pyramid", "polygon", "spline", and "line". Try it on JSFiddle.
    Default value: false.
    options.prepareDataFunction
    Function
    optional If the connector does not include the necessary type of chart or if you need to preprocess the data differently, use this function. prepareDataFunction takes two input parameters:
    • rawData – the raw data (check out the structure of rawData in getData()).
    • options – an object with options set in the highcharts.getData() function.
    Try it on JSFiddle.
    callbackHandler
    Function
    Specifies what will happen once the data is ready. Additional options can be specified and then data can be passed directly to the charting library. Takes two input parameters: chartConfig and rawData (rawData is passed just in case you need it, for example for defining number formatting in the tooltip).
    updateHandler
    Function
    optional Takes two input parameters: chartConfig and rawData. Specifies what will happen once data in the pivot table is filtered/sorted/etc or a number format is changed.

    The connector has several functions for defining number formatting for Highcharts. All these functions take the pivot table FormatObject and return the formatting string in Highcharts format. The Highcharts format string is a template for labels with one of the following variables inserted in a bracket notation: value, point.x, point.y, or point.z. For example, "{value:.2f}" is for two decimal places. Thus, there are four functions in the connector that convert the Flexmonster's FormatObject to the Highcharts format string (refer to the Highcharts documentation for more details about the format strings).

    • highcharts.getAxisFormat(format) – String. Takes the pivot table FormatObject and returns the Highcharts format string with the value variable.
    • highcharts.getPointXFormat(format) – String. Takes the pivot table FormatObject and returns the Highcharts format string with the point.x variable.
    • highcharts.getPointYFormat(format) – String. Takes the pivot table FormatObject and returns the Highcharts format string with the point.y variable.
    • highcharts.getPointZFormat(format) – String. Takes the pivot table FormatObject and returns the Highcharts format string with the point.z variable.

    These functions can be used in both callbackHandler and updateHandler to define the number formatting for axes and tooltips. Try it on JSFiddle.
