• HighCharts使用心得


    HighCharts使用心得

    前言:

    之前很早的一个项目中使用过highcharts,感觉挺方便的,图表类型也比较丰富,而且还支持数据的下钻,但是如果投入商业使用的话还会有一些版权的问题,所以后来就使用了EChart,这是百度开发的一个开源的图表插件,图表类型也很丰富,而且还有交互,对地图的支持也很好,可以免费的使用。在之前的一篇文章里,已经总结过了,今天主要跟大家分享一下,之前总结的Highcharts的一些使用心得,希望能够对大家有所帮助。

    1.  准备工作------下载HighCharts插件

    跟ECharts一样,HighCharts也需要下载相应的插件,不过HightCharts的插件很简单,只有一个highcharts.js文件。可以从HighCharts官网上下载,具体地址如下:http://www.highcharts.com/download

    另注:

    如果需要导出图表,则需要exporting.js文件

    如果需要一些特殊的图形呈现,则还需要下载highcharts-more.js

    2.  新建一个解决方案或网站,引用下载的highcharts.js文件,进行图表展示。

    在这个过程中,我会逐步的跟大家讲解如何使用highcharts.js进行图表展示。

    2.1 新建解决方案(或网站),目录结构如下

     

    另注:

    一般情况下如果不需要导出图片、且只使用常规的图形,exportting.js和highchart-more.js可以不要,只留一个highcharts.js文件即可。

    其中的HighCharts.js文件为我自己总结的使用帮助文件,主要用来配置图表类型、图表数据的处理、格式化等操作,下边会进一步讲解。

                 此外需要注意的是这里引用的Jquery文件版本为最近版本,VS里边默认的为1.4.1的版本太低,最新的highcharts需要高版本的jQuery文件。

    2.2 HighChart.js文件介绍

    在2.1中对此文件有一个初步的介绍,这一小节里专门来介绍这个文件。该文件的主要功能是用来配置各种图表类型的配置项,同时对用户提供的参数进行格式化、图表的呈现等功能。

    文件的目录结构如下:

    var HighChart = {
    
        ChartDataFormate: {//数据格式化
    
            FormateNOGroupData: function (data) {//处理不分组的数据
    
                var categories = [];
    
                var datas = [];
    
                for (var i = 0; i < data.length; i++) {
    
                    categories.push(data[i].name || "");
    
                    datas.push([data[i].name, data[i].value || 0]);
    
                }
    
                return { category: categories, data: datas };
    
            },…………
    
           },
    
        ChartOptionTemplates: {//图表配置项
    
            Pie: function (data, name, title) {
    
                var pie_datas = HighChart.ChartDataFormate.FormateNOGroupData(data);
    
                var option = {
    
                    chart: {
    
                        plotBackgroundColor: null,
    
                        plotBorderWidth: null,
    
                        plotShadow: false
    
                    },
    
                   …….
    
                };
    
                return option;
    
            },
    
        RenderChart: function (option, container) {//页面渲染
    
            container.highcharts(option);
    
        }

    后记:

          这里只是列出了常用的一些图表类型,如果有特殊需要的话还可以进行自主的去抽象扩展。后续有时间的话,我也会对新的图表类型进行扩展,还有,关于HighChart里边的数据下钻的功能,这里也没有列出来,个人觉得这种图表的交互,抽象出来意义不是很大,后续再看看吧,有时间的话就再试着弄弄。
