本节主要介绍百度echarts柱状图的实现,实现步骤如下

一、饼图实现

1,新建demo.html页面,并引入echarts的js库,在这里我们引入的是网络地址

<script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/echarts-all-3.js"></script>

2,饼图容器html代码,只需一行html代码

<div id="container" style="height: 500px"></div>

饼图容器高度为500px,宽度默认,并且div的id号为container,在接下来初始化饼图的时候会用到。

3,javascript实现代码

<script type="text/javascript">
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
var app = {};
var option = null;
app.title = '坐标轴刻度与标签对齐';

option = {
    backgroundColor: '#2c343c',

    title: {
        text: 'Customized Pie',
        left: 'center',
        top: 20,
        textStyle: {
            color: '#ccc'
        }
    },

    tooltip : {
        trigger: 'item',
        formatter: "{a} <br/>{b} : {c} ({d}%)"
    },

    visualMap: {
        show: false,
        min: 80,
        max: 600,
        inRange: {
            colorLightness: [0, 1]
        }
    },
    series : [
        {
            name:'访问来源',
            type:'pie',
            radius : '55%',
            center: ['50%', '50%'],
            data:[
                {value:335, name:'直接访问'},
                {value:310, name:'邮件营销'},
                {value:274, name:'联盟广告'},
                {value:235, name:'视频广告'},
                {value:400, name:'搜索引擎'}
            ].sort(function (a, b) { return a.value - b.value}),
            roseType: 'angle',
            label: {
                normal: {
                    textStyle: {
                        color: 'rgba(255, 255, 255, 0.3)'
                    }
                }
            },
            labelLine: {
                normal: {
                    lineStyle: {
                        color: 'rgba(255, 255, 255, 0.3)'
                    },
                    smooth: 0.2,
                    length: 10,
                    length2: 20
                }
            },
            itemStyle: {
                normal: {
                    color: '#c23531',
                    shadowBlur: 200,
                    shadowColor: 'rgba(0, 0, 0, 0.5)'
                }
            }
        }
    ]
};



if (option && typeof option === "object") {
    myChart.setOption(option, true);
}
       </script>

4,用浏览器打开demo.html,效果如下


demo.html完整代码

<!DOCTYPE html>
<head>
       <meta charset="utf-8">
   </head>
   <body >
       <div id="container" style="height: 500px"></div>
       
       <!-- V型知识库 www.vxzsk.com -->

option = {
    backgroundColor: '#2c343c',

        text: 'Customized Pie',

        }
    },
    series : [

                {value:274, name:'联盟广告'},
                {value:235, name:'视频广告'},
                {value:400, name:'搜索引擎'}
            ].sort(function (a, b) { return a.value - b.value}),
            roseType: 'angle',
            label: {
                normal: {
                    textStyle: {
                        color: 'rgba(255, 255, 255, 0.3)'
                    }
                }
            },
            labelLine: {
                normal: {
                    lineStyle: {
                        color: 'rgba(255, 255, 255, 0.3)'
                    },
                    smooth: 0.2,
                    length: 10,
                    length2: 20
                }
            },
            itemStyle: {
                normal: {
                    color: '#c23531',
                    shadowBlur: 200,
                    shadowColor: 'rgba(0, 0, 0, 0.5)'
                }
            }
        }
    ]
};



if (option && typeof option === "object") {
    myChart.setOption(option, true);
}
       </script>
   </body>
