Connecting to JSON

This article illustrates how to build a report based on a JSON data source. The most simple configuration to use a JSON data source is to display data that is already on your page. Alternatively, you can load JSON data from your local file system (see Connect > To local JSON in the Toolbar), refer to a remote JSON file, or add data generated by a server-side script.

The component supports two JSON formats – an array of objects, where each object is an unordered set of name/value pairs, and an array of arrays, where each sub-array contains ordered values. See the array of objects sample below:

var jsonData = [
    {
        "Color" : "green",
        "Country" : "Canada",
        "State" : "Ontario",
        "City" : "Toronto",
        "Price" : 174,
        "Quantity" : 22
    },
    {
        "Color" : "red",
        "Country" : "USA",
        "State" : "California",
        "City" : "Los Angeles",
        "Price" : 166,
        "Quantity" : 19
    }
];

The following sample demonstrates what a JSON format with an array of arrays looks like:

var jsonData = [
    [
        "Category",
        "Color",
        "Price",
        "Quantity"
    ],
    ["Ice-cream", "red", 23.32, 4],
    ["Ice-cream", "yellow", 4.2, 3],
    ["Sweets", "red", 45.3, 2],
    ["Candies", "orange", 22.65, 7]
];

To use JSON data as a data source in the pivot table embedded in your project, follow these steps:

  1. Set up an empty component in your HTML page. If Flexmonster is not yet embedded – return to Quick start. Your code should look similar to the following example:

    <div id="pivotContainer">The component will appear here</div>
    <script src="flexmonster/flexmonster.js"></script>
    <script>
    	var pivot = new Flexmonster({
    		container: "pivotContainer",
    		toolbar: true,
    		licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
    	});
    </script>
    
  2. Copy the following JSON and paste it into your HTML page:
    <div id="pivotContainer">The component will appear here</div>
    <script src="flexmonster/flexmonster.js"></script>
    
    <script>
    
    	var jsonData = [
    	{
    		"Color" : "green",
    		"Country" : "Canada",
    		"State" : "Ontario",
    		"City" : "Toronto",
    		"Price" : 174,
    		"Quantity" : 22
    	},
    	{
    		"Color" : "red",
    		"Country" : "USA",
    		"State" : "California",
    		"City" : "Los Angeles",
    		"Price" : 166,
    		"Quantity" : 19
    	}
    	];
    
    
    	var pivot = new Flexmonster({
    		container: "pivotContainer",
    		toolbar: true,
    		licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
    	});
    </script>
  3. Add the data property to the report object:
    <div id="pivotContainer">The component will appear here</div>
    <script src="flexmonster/flexmonster.js"></script>
    
    <script>
    	var jsonData = [
    	{
    		"Color" : "green",
    		"Country" : "Canada",
    		"State" : "Ontario",
    		"City" : "Toronto",
    		"Price" : 174,
    		"Quantity" : 22
    	},
    	{
    		"Color" : "red",
    		"Country" : "USA",
    		"State" : "California",
    		"City" : "Los Angeles",
    		"Price" : 166,
    		"Quantity" : 19
    	}
    	];
    
    	var pivot = new Flexmonster({
    		container: "pivotContainer",
    		toolbar: true,
    		report: {
    			dataSource: {
    				data: jsonData
    			}
    		},
    		licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
    	});
    </script>
  4. Define a slice – fields that go to rows, go to columns and go to measures:
    <div id="pivotContainer">The component will appear here</div>
    <script src="flexmonster/flexmonster.js"></script>
    
    <script>
    	var jsonData = [
    	{
    		"Color" : "green",
    		"Country" : "Canada",
    		"State" : "Ontario",
    		"City" : "Toronto",
    		"Price" : 174,
    		"Quantity" : 22
    	},
    	{
    		"Color" : "red",
    		"Country" : "USA",
    		"State" : "California",
    		"City" : "Los Angeles",
    		"Price" : 166,
    		"Quantity" : 19
    	}
    	];
    
    	var pivot = new Flexmonster({
    		container: "pivotContainer",
    		toolbar: true,
    		report: {
    			dataSource: {
    				data: jsonData
    			},
    			slice: {
    				rows: [
    				{ uniqueName: "Color" },
    				{ uniqueName: "[Measures]" }
    				],
    				columns: [
    				{ uniqueName: "Country" }
    				],
    				measures: [
    				{
    					uniqueName: "Price", 
    					aggregation: "sum" 
    				}
    				]
    			}
    		},
    		licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
    	});
    </script>
  5. Now launch the page from the browser — there you go! A pivot table based on JSON data is embedded into your project. Check out this example on JSFiddle.

Now you know how to build a report based on our sample JSON. This example shows how to use a JSON array of arrays. The next step for you is to visualize your JSON data.

How to display non-English characters correctly

If you use an alphabet with special characters you must use UTF-8 encoding. There are two ways to do this:

  1. Specify the encoding for your HTML page to UTF-8 using the content-type HTTP header or the corresponding meta tag:
    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    Content from a database and static JSON files also must be encoded as UTF-8.
  2. If you are not able to change the content of your HTML file, you can embed Flexmonster Pivot in a separate JS file with specified UTF-8 encoding.
    <script src="yourfile.js" charset="UTF-8"></script>
