ECharts介绍
- Echarts是一个使用Javascript实现的开源可视化库，兼容性强，底层依赖矢量图形库ZRender，提供直观丰富，交互丰富，可高度个性化定制的数据可视化图表
快速入门 (柱状图)
- 引入echarts.min.js文件
- 创建dom元素
- 基于dom元素进行实例化echarts
- 使用dom和echats配置显示图标

相关配置项
- xAxis：x轴
xAxis: {
type:'category', //类目轴
data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
},
- yAxis：y轴
yAxis: {
type:'value', //数值轴 不需要设置data属性 根据x轴的类别去series找对应的数值
},
- series：系列列表。每个系列通过type决定自己的图表类型
series: [{
name: '销量',
type: 'pie', //bar 代表柱状图 line 折线图 pie 饼状图
data: [5, 20, 36, 10, 10, 20]
}]
https://github.com/SuperZDev/echarts-doc-offline
常用效果
series: [
{
name: '销量',
type: 'bar', //bar 代表柱状图 line 折线图
data: [5, 20, 36, 10, 10, 20],
//标记 最大值 最小值
markPoint:{
data:[
{
type:'max',name:'最大值'
},
{
type:'min',name:'最小值'
}
]
},
// 平均值
markLine:{
data:[
{
type:'average',name:'平均值'
}
]
},
// 标识
label:{
show:true, //是否显示
rotate:0, //旋转60°
position:'inside'
},
// 柱子的宽度
barWidth:'30%',
}
]
通用配置
-
任何图标都可以使用的配置
-
tiltle标题
title: {
//边框
text: '第一个 ECharts 实例',
link:'http://www.itcast.cn',
borderWidth:5,
borderColor:'blue',
//文字样式
textStyle:{
color:'red'
},
//位置
top:30,
left:10
},
- tooltip：提示框组件，用于配置鼠标滑过出现提示框
tooltip: {
show:true,
//触发类型
trigger:'axis' ,// item一定要移入内部
triggerOn:'click', //click点击才会触发 默认书鼠标经过就出现提示
// formatter:'{b}的销量是{c}' //内容决定提示框内的内容
formatter:function(arg){
console.log(arg);
return arg[0].name + "的销量111是" +arg[0].data
},
},
- toolbox：提供的内置工具栏
- 导出图片，数据视图，动态类型切换，数据区域缩放，重置五个工具
toolbox:{
feature:{
//导出图片
saveAsImage:{},
//数据视图
dataView:{},
//重置
restore:{},
//区域缩放
dataZoom:{},
//不同图标之间切换
magicType:{
type:['bar','line']
}
}
},
- legend：图例，用于筛选系列，需要和series配和使用
- legend数组里的值需要和series里面的name的值相同
legend: {
data:['销量','库存']
},
series: [
{
name: '销量',
type: 'bar', //bar 代表柱状图 line 折线图
data: [5, 20, 36, 10, 10, 20],
},
{
name: '库存',
type: 'bar', //bar 代表柱状图 line 折线图
data: [211, 211, 300, 100, 100, 120],
}
]
