Highchart speedometer take input from csv - csv

Question

I am trying to read the data from csv and display it as a input to Speedometer but I am unable to get the chart. Please tell me where i am going wrong.
My code is:
$(document).ready(function() {
var options = {
chart: {
type: 'gauge',
plotBackgroundColor: null,
plotBackgroundImage: null,
plotBorderWidth: 0,
plotShadow: false
},
title: {
text: 'Speedometer'
},
pane: {
startAngle: -150,
endAngle: 150,
background: [{
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },
stops: [
[0, '#FFF'],
[1, '#333']
]
},
borderWidth: 0,
outerRadius: '109%'
}, {
backgroundColor: {
linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 },
stops: [
[0, '#333'],
[1, '#FFF']
]
},
borderWidth: 1,
outerRadius: '107%'
}, {
// default background
}, {
backgroundColor: '#DDD',
borderWidth: 0,
outerRadius: '105%',
innerRadius: '103%'
}]
},
// the value axis
yAxis: {
min: 0,
max: 100,
minorTickInterval: 'auto',
minorTickWidth: 1,
minorTickLength: 10,
minorTickPosition: 'inside',
minorTickColor: '#666',
tickPixelInterval: 30,
tickWidth: 2,
tickPosition: 'inside',
tickLength: 10,
tickColor: '#666',
labels: {
step: 2,
rotation: 'auto'
},
title: {
text: 'km/h'
},
plotBands: [{
from: 0,
to: 120,
color: '#55BF3B' // green
}, {
from: 120,
to: 160,
color: '#DDDF0D' // yellow
}, {
from: 160,
to: 200,
color: '#DF5353' // red
}]
},
series: []
};
$.get('data.csv', function(data) {
var series = {
data: [],
name: 'Speed',
tooltip: {
valueSuffix: ' km/h'
}
};
series.data.push(parseFloat(data));
options.series.push(series);
alert("data "+options.series);
var chart = new Highcharts.Chart(options);
});
});
and the csv file is simple
data.csv has only one value 30.
or incase it is
t1,30
t2,40
t3,60
how do i display 3 corresponding speedometers with respective speed.
Your help is greatly appreciated.
Thanks in advance.

In your case data your data (from ajax) is a single string, but you need to split elements and then choose which should be parsed to integer (parseFloat).
