使用hcharts创建漏斗图/How to use hcharts to make a funnel chart

in #utopian-io7 years ago (edited)

Summary:
Javascript has a lot of open source chart Libraries,Hcharts.js is one of them,today i will show you how to create a funnel chart by Hcharts.

Javascript 有很多开源图表库,Hcharts.js就是其中之一,今天教程将教大家如何使用Hcharts.js去绘制一张漏斗图。

  • 兼容浏览器:IE, Chrome,Firefox等等

您能从本教程学到什么?

  • 代码整体结构
  • 怎么调用hcharts.js
  • 怎么设置图表画布大小以及图表chart配置
  • 怎么设置图表主副标题
  • 怎么设置通用配置
  • 怎么设置图例
  • 怎么设置数据列

需要的准备条件

  • 你需要一个代码编辑器,比如atom,EmEditor等等,当然因为是文本编辑,可以直接通过浏览器打开,typora这类文本编辑器也可以进行代码编辑。
  • 你需要下载hcharts.js(如果不下载到本地,也可以在线调用,参考要点2.

本教程难度

相对来说比较简单,只需要对固定代码格式有些简单了解,就可以绘制漏斗图。

  • 认识简单代码
  • 认识简单英文

教程内容

下面请先看一个简单例子:

要点1:代码整体结构
<html>
<head>
<meta charset="utf-8">
<title>title</title>
<script src="https://img.hcharts.cn/jquery/jquery-1.8.3.min.js"></script>
<script src="https://img.hcharts.cn/highcharts/highcharts.js"></script>
<script src="https://img.hcharts.cn/highcharts/highcharts-more.js"></script>
<script src="https://img.hcharts.cn/highcharts/modules/exporting.js"></script>
<script src="https://img.hcharts.cn/highcharts-plugins/highcharts-zh_CN.js"></script>
</head>
<body>
<div id="container" style="height: 400px"></div>
<script>
    $(function () {
        $('#container').highcharts({
       //key code
        })
//hcharts.js  code area!
</script>
</body>
</html>

html结构,我们创建图表的代码是js语句,所以关键代码是放在< script>里面。下面将详细讲解关键代码。

要点2:怎么调用hcharts.js
<script src="https://img.hcharts.cn/jquery/jquery-1.8.3.min.js"></script>
<script src="https://img.hcharts.cn/highcharts/highcharts.js"></script>
<script src="https://img.hcharts.cn/highcharts/highcharts-more.js"></script>
<script src="https://img.hcharts.cn/highcharts/modules/exporting.js"></script>
<script src="https://img.hcharts.cn/highcharts-plugins/highcharts-zh_CN.js"></script>

如果本地没有hcharts.js库,可以使用其在线js资源,同时需要加载jquery.min.js。直接在head区域引用就可以了。

要点3:怎么设置图表画布大小
<div id="container" style="min-width: 410px; max-width: 600px; height: 400px; margin: 0 auto"></div>

在body区域,编辑chartjs代码之前,需要先定义下图表的大小。上面代码定义,最小宽度410px,最大宽度600px,高为400px。

 chart: {
            type: 'funnel',
            marginRight: 100
        },

type:图表 类型,默认是line,这里是漏斗图,所以设置为funnel。

marginRight:右外边距

要点4:怎么设置图表主副标题
  title: {
            text: 'funnel chart',
            x: -50
        },
subtitle: {
            text: 'This is a demo <br/>@jubi',
            x: -50
        },

titel:标题,text后输入标题文本,支持html标签。

subtitle:副标题,text后输入标题文本,支持html标签。实例如下:

360截图20180124231950639.jpg

x为,标题水平方向的偏移量,可通过更改数值来改变水平方向上标题的位置。

要点5:怎么设置通用配置
 plotOptions: {
            series: {
                dataLabels: {
                    enabled: true,
                    crop : false,
                    overflow: 'justify',
                    format: '<b>{point.name}</b> ({point.y:,.0f})',
                    color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black',
                    softConnector: true
                },
                neckWidth: '30%',
                neckHeight: '25%'
            }
        },

enabled: 标签是否显示,设置为true 显示标签,false则不显示。

  • enabled:true 实例如下:

360截图20180124232323041.jpg

  • enabled:false实例如下:

360截图20180124232333914.jpg

crop:标签是否裁剪。设置为true, 则超出范围的标签不显示或者显示不全,false则不裁剪。

  • crop : false 实例如下:

360截图20180124232559659.jpg

  • crop : true实例如下:

360截图20180124232625709.jpg

format 数据点显示样式,实例如下:

360截图20180124232854468.jpg

color 颜色设置

neckWidth/neckHeight 设置漏斗图宽和高

要点6:怎么设置图例
 legend: {
            enabled: false
        },

漏斗图本身就不需要图例,所以此处参数设置为false,当然这段代码也可以直接不写。

要点7:怎么设置数据列
series: [{
            name: 'users-demo',
            data: [
                ['A',154],
                ['B',44],
                ['C',197],
                ['D',96],
                ['E',46]
            ]
        }]

name 数据名称

data 具体数据 格式为:data:[['name1',data1],['name2',data2]……]

完整实例如下:

                neckHeight: '25%'
                //-- Other available options
                // height: pixels or percent
                // width: pixels or percent
            }
        },
