Ok, ecco una soluzione completa:
<!DOCTYPE html><html><head>
</head><body>
<div id="container" style="height: 400px; width: 900px"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script src="https://www.highcharts.com/js/highcharts.src.js"></script>
<script>
jQuery(function($) {
var options = {
chart: {renderTo: 'container', defaultSeriesType:'spline', height: 400},
title: {text: 'SEN-2 Bulkhead Isolation'},
xAxis: {title: {text: 'Frequency Hz'}, type: 'logarithmic'},
yAxis: {title: {text: 'Isolation dB'}, plotLines: [{ value: 0, width: 1, color: '#808080'}]},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+'('+this.x +' : '+ this.y +')';
}
},
legend: {layout: 'vertical', align: 'right', verticalAlign: 'top', x: 40, y: 100, borderWidth: 0, width: 300 },
series: []
};
jQuery.get('data2.php', null, function(tsv) {
var data = {};
tsv = tsv.split(/\n/g); // split into rows
for (var row=0, rows=tsv.length; row<rows; row++) {
var line = tsv[row].split(/\t/g), // split into columns
series_name = line[0],
x = Number(line[1]),
y = Number(line[2]);
if (!data[series_name]) data[series_name] = [];
data[series_name].push([x,y]);
}
for (var series_name in data) {
options.series.push({
name: series_name,
data: data[series_name]
});
}
new Highcharts.Chart(options);
});
});
</script>
</body></html>
L'ho testato con questi dati TSV:
SSTP Keystone STEEL 0.6 74.9
SSTP Keystone STEEL 0.895 81.74
SSTP Keystone STEEL 1.336 77.26
SSTP Keystone STEEL 1.993 76.81
SSTP Keystone STEEL 2.974 80.45
SSTP Keystone STEEL 4.438 69.41
SSTP Keystone STEEL 6.622 61.37
SSTP Keystone STEEL 9.881 79.07
SSTP Keystone STEEL 14.744 79.75
SSTP Keystone STEEL 20.000 72.33
Quello che sto facendo è scorrere il TSV e creare i data variabile come un array associativo digitato sul nome della serie, in questo modo:
{
'SSTP Keystone STEEL': [[0.6,74.9],[0.895,81.74],...],
...
}
Quindi sto scorrendo i data variabile e costruendo options.series nel formato previsto da HighCharts:un array di oggetti con un name proprietà e un data proprietà.
