一:HighChart介绍

基于JQuery的纯JavaScript的图标库,支持各种图表显示,同时还支持Mootools

与Prototype详细版本支持在这里:

JQuery

1.3.2 - 1.9.x. 2.0.x for modern browsers

Mootools

1.2.5 - 1.4.5

Prototype

1.7

支持目前市场几乎所有的主要浏览器IE, Chrome, FF,Safari, Opera等。其图形渲染完

全是是基于SVG与VML方式,其中VML方式主要是兼容IE浏览器,在IE9+及其它浏览

器上渲染技术都是基于SVG方式。下载与安装指导文档

->http://docs.highcharts.com/#home安装好以后,建一个基本static web 项目,如图

二:HighChart基本的Bar Chart演示

打开链接->http://docs.highcharts.com/#your-first-chart

拷贝your first chart中第二步中的全部script脚本到mydemo.html中的<script></script>

之间。导入JQuery与highchart库文件支持。代码如下:

<scriptsrc="static/jquery-1.9.1/jquery-1.9.1.min.js"></script>

<scriptsrc="static/highcharts-3.0.1/js/highcharts.js"></script>

在tomcat中部署demo1之后访问如下URL:http://localhost:8080/demo1/mydemo.html

在浏览器中看到如下Bar Chart:

三:清除HighChart中的数据集(remove data series from high chart object)

代码修改:

1.      把type:’bar’ 改成type: ’column’ 其作用是让bar垂直显示

2.      向script尾部追加如下代码,自动清除所有series然后刷新

setTimeout(function(){

var series=chart.series;

while(series.length > 0) {

series[0].remove(false);

}

chart.redraw();

},2000);

四:向HighChart中添加data series(add new data series into high chart object)

向script的尾部追加如下代码,实现添加data series并刷新bar chart

setTimeout(function(){

chart.addSeries({

id:1,

name:"gloomyfish",

data:[1,2,3]

},false);

chart.addSeries({

id:2,

name:"wang-er-ma",

data:[5,2,1]

},false);

chart.addSeries({

id:3,

name:"zhang-san",

data:[4,8,6]

},false);

chart.redraw();

},2000);

addSeries方法中第二个参数false表示不重绘plot,等所有series添加完成调用redraw

方法重绘。

五:在chart中清除high chart官方链接(remove high chart official hyperlink in chart)

仔细观察在Bar Chart的右下角有个highchart的官方链接,当然希望去掉,只要在chart

声明中将credits声明设置改为false即可。代码如下:

credits: {enabled: false// remove high chart logo hyper-link},

<script>
$(function() {
var chart; // initialization chart and actions
$(document).ready(function () {
chart = new Highcharts.Chart({

},

},
xAxis: {

},
series: [{
name: 'Jane',
data: [1, 0, 4]
}, {
name: 'John',
data: [5, 7, 3]
}]
}); // JQuery, mouse click event bind with dom buttons
$('#clear-button').on('click', function (e) {
clearPlot();
}); $('#refresh-button').on('click', function (e) {
refreshPlot();
});
}); // clear all series of the chart
function clearPlot() {
//console.log("clear plot data!!!");
var series=chart.series;
while(series.length > 0) {
series[0].remove(false);
}
chart.redraw();
}; function refreshPlot() {
//console.log("refresh plot data!!!");
chart.addSeries({
id:1,
name: "gloomyfish",
data: [1,2,3]
}, false);
chart.addSeries({
id:2,
name: "wang-er-ma",
data: [5,2,1]
}, false);
chart.addSeries({
id:3,
name: "zhang-san",
data: [4,8,6]
}, false); chart.redraw();
}; setTimeout(function(){
var series=chart.series;
while(series.length > 0) {
series[0].remove(false);
}
chart.redraw();
},2000); // add new series for the chart
setTimeout(function(){
chart.addSeries({
id:1,
name: "gloomyfish",
data: [1,2,3]
}, false);
chart.addSeries({
id:2,
name: "wang-er-ma",
data: [5,2,1]
}, false);
chart.addSeries({
id:3,
name: "zhang-san",
data: [4,8,6]
}, false); chart.redraw();
},2000);
});
</script>

<body>
<h1>High Chart Demo 1</h1>
<div id="my_container" style="width:600px; height:600px;"></div>
<div id="btn-group">
<button type="button" id="clear-button">Clear Plot</button>
