Highchart and json with codeigniter |
Hi
I am using Highchart with Codeigniter. I am displaying project requests for different months. The Graph is displaying fine but the x-axis values are showing numneric values (0,1,2...) instead of month names. Here is my controller code: public function data() { $data = $this->project->get_data(); $ab = array(); $category['name'] = 'Category'; $series1 = array(); $series1['name'] = 'WordPress'; $series2 = array(); $series2['name'] = 'Code Igniter'; $series3 = array(); $series3['name'] = 'Highcharts'; foreach ($data as $row) { $category['data'][] = $row->month; $series1['data'][] = $row->wordpress; $series2['data'][] = $row->codeigniter; $series3['data'][] = $row->highcharts; } $result = array(); $result1 = array(); array_push($result1,$category); array_push($result,$series1); array_push($result,$series2); array_push($result,$series3); $this->view_data['ctg'] = json_encode($result1, JSON_NUMERIC_CHECK); $this->view_data['series_data'] = json_encode($result, JSON_NUMERIC_CHECK); $this->load->view('chart_high', $this->view_data); } Given below is the chart_high view: <!DOCTYPE HTML> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Line Chart</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <script type="text/javascript"> var test = $(function () { $('#container').highcharts({ chart: { renderTo: 'container', type: 'column', marginRight: 130, marginBottom: 25 }, title: { text: 'Project Requests', x: -20 //center }, subtitle: { text: '', x: -20 }, xAxis: { categories: [] }, yAxis: { title: { text: 'Requests' }, plotLines: [{ value: 0, width: 1, color: '#808080' }] }, tooltip: { formatter: function() { return '<b>'+ this.series.name +'</b><br/>'+ this.x +': '+ this.y; } }, credits: { enabled: false }, legend: { layout: 'vertical', align: 'right', verticalAlign: 'top', x: -10, y: 100, borderWidth: 0 }, series: <?php echo $series_data ?> }); }); </script> <script type="text/javascript" language="javascript" src="<?php echo base_url(); ?>js/highcharts.js"></script> <script type="text/javascript" language="javascript" src="<?php echo base_url(); ?>js/exporting.js"></script> </head> <body> <div id="container" style="min-width: 400px; height: 400px; margin: 0 auto"></div> </body> </html> If I hardcode the categories as ["January","February"], then the x-axis values are showing as January, February etc like the way I want. Please help me in this regard. Thanks in advance,

I have solved it using the code: $ctg=$category['month']; $this->view_data['month'] = json_encode($ctg, JSON_NUMERIC_CHECK); Then in chart_high view, I used xAxis: { categories: <?php echo $month ; ?> }, Now the months are displayed in x-axis as January, February, March..etc. I have searched in many forums including stackoverflow but didnt find any solution. I am posting as it may help someone in future. |
