These days I'm doing CodeIgniter project, need chart library. I tried pChart, chartdirector,Highcharts etc.
I have to say Highcharts is the easiest to use, other tools like pChart, chartdirector need to write a extra library in CodeIgniter to use them,it's not convenient, but Highcharts no need.
Highcharts is a charting library written in pure JavaScript, all you need is down load Highcharts and jquery then put them into your CodeIgniter directory.
How to use? Look at here: http://www.highcharts.com/documentation/how-to-use
<script src="/js/jquery.js" type="text/javascript"></script>
<script src="/js/highcharts.js" type="text/javascript"></script>
<script type="text/javascript">
var chart1; // globally available
jQuery(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container'
},
title: {
text: 'Combination chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Bananas', 'Plums']
},
tooltip: {
formatter: function() {
var s;
if (this.point.name) { // the pie chart
s = ''+
this.point.name +': '+ this.y +' fruits';
} else {
s = ''+
this.x +': '+ this.y;
}
return s;
}
},
labels: {
items: [{
html: 'Total fruit consumption',
style: {
left: '40px',
top: '8px',
color: 'black'
}
}]
},
series: [{
type: 'column',
name: 'Jane',
data: [3, 2, 1, 3, 4]
}, {
type: 'column',
name: 'John',
data: [2, 3, 5, 7, 6]
}, {
type: 'column',
name: 'Joe',
data: [4, 3, 3, 9, 0]
}, {
type: 'spline',
name: 'Average',
data: [3, 2.67, 3, 6.33, 3.33],
marker: {
lineWidth: 2,
lineColor: Highcharts.getOptions().colors[3],
fillColor: 'white'
}
}, {
type: 'pie',
name: 'Total consumption',
data: [{
name: 'Jane',
y: 13,
color: '#4572A7' // Jane's color
}, {
name: 'John',
y: 23,
color: '#AA4643' // John's color
}, {
name: 'Joe',
y: 19,
color: '#89A54E' // Joe's color
}],
center: [100, 80],
size: 100,
showInLegend: false,
dataLabels: {
enabled: false
}
}]
});
});
</script>
<div id="chartcontainer"></div>
The above script will draw a combination of column line pie chart like bellow.
Highcharts got a lot of demo which is very convenient for you to draw a chart, check
