  • HighChart学习-更新数据data Series与重绘

    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

    所示:

    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},
