    <p>I made a spline chart using Highcharts library containing two series of data loaded from two different CSV files and it works fine. Now I need another spline chart, but with 54 data series.</p> <p>I used PHP to create the 54 CSV files, then my Javascript code generating the chart is:</p> <pre><code>&lt;script type="text/javascript"&gt; $(function () { var chart; $(document).ready(function() { var options = { chart: { renderTo: 'chart_day', type: 'spline' }, title: { text: 'Andamento giornaliero temperatura.' }, xAxis: { type: 'datetime', second: '%H:%M:%S' }, yAxis: { title: { text: 'Temperatura (°C)' }, }, tooltip: { formatter: function() { return '&lt;b&gt;'+ this.series.name +'&lt;/b&gt;&lt;br/&gt;'+ Highcharts.dateFormat('%H:%M:%S', this.x) +': '+ this.y +' °C'; } }, series: [ &lt;?php for($i=0;$i&lt;52;$i++) echo "{ name: \"Sensor".($i+1)."\", data: []},"; echo "{ name: \"Sensor".($i+1)."\", data: []}"; ?&gt;] }; for( i=1; i&lt;=54; i++){ if(i!=5){ $.get('file/file'+i+'.txt', function(data) { // Split the lines var lines = data.split('\n'); // Iterate over the lines and add categories or series $.each(lines, function(lineNo,line) { if (line != "") { var items = line.split(','); var timeElements = items[0].split(':'); var date = Date.UTC(2004, 2, 1, timeElements[0], timeElements[1], timeElements[2], 0); options.series[i-1].data.push([date,parseFloat(items[1])]); } }); if(i==54) chart = new Highcharts.Chart(options); }); } } }); }); &lt;/script&gt; </code></pre> <p>There is an error in the JS consolle: </p> <blockquote> <p>"Uncaught TypeError: Cannot read property 'data' of undefined "</p> </blockquote>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
