    <p>I am trying to make a highcharts chart similar to the one in this demo: <a href="http://www.highcharts.com/demo/column-basic" rel="nofollow">http://www.highcharts.com/demo/column-basic</a> with json data, but I cant see how I can parse my json data in a sensible matter. My data is grouped by week-day, and has three categories. The following is an example:</p> <pre><code>{ "Monday": { "inv": 1126, "oppm": 276, "perc": "24.51" }, "Tuesday": { "inv": 1072, "oppm": 273, "perc": "25.47" }, "Wednesday": { "inv": 1032, "oppm": 271, "perc": "26.26" }, "Thursday": { "inv": 989, "oppm": 259, "perc": "26.19" }, "Friday": { "inv": 937, "oppm": 240, "perc": "25.61" } } </code></pre> <p>Is there a way to do this in a simple matter? Would it help if I changed my json data structure?</p> <p>Thanks in advance!</p> <p><strong>EDIT: Solution:</strong></p> <p>I found a not-too-complicated way of doing it, although I'm sure it could be done even easier if you know your JS. This solution works nicely with my JSON data anyway:</p> <pre><code>//Convert received AJAX data success: function(data) { cleanData = $.parseJSON(data); //Make some empty arrays for the categories and data days = Array(); inv = Array(); oppm = Array(); perc = Array(); //Iterate the data and fill in the new arrays $.each(cleanData, function(index, value) { days.push(index); inv.push(parseFloat(value['inv'])); oppm.push(parseFloat(value['oppm'])); perc.push(parseFloat(value['perc'])); }); //Use the new arrays in the chart chart1 = new Highcharts.Chart({ chart: { renderTo: 'div_chart', type: 'column' }, xAxis:{ categories: days, title: { text: 'Week day' } }, series: [{ name: 'Invited', data: inv }, { name: 'Met', data: oppm }, { name: '%', data: perc }], }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
