Introduction to Echarts and use of common settings

ECharts is a pure JavaScript chart library. The bottom layer depends on the lightweight Canvas class library ZRender. Based on the BSD open source protocol, it is a very good visual front-end framework.

2. Introduction of Echarts

npm installation method: npm install echarts --save

3. Simple use of attributes and custom styles

3.1. The customized renderings are as follows:

3.2, first prepare a DOM container

<div id="container" style="width:100%;height:400px;"></div>

3.3, draw a line chart

// 引入 ECharts 主模块
import echarts from 'echarts';

// 基于准备好的dom，初始化echarts实例
			var myChart = echarts.init(document.getElementById('container'));
			// 绘制图表
			myChart.setOption({
				title: {
					// text: '标题设置'
				},
				tooltip: {
					trigger: 'axis',
					formatter: function(data) { //此处是当鼠标移到折线点的展示样式  自定义内容
						return (
							data[0].name +
							'<br/><span style="background: #2062E6;width: 10px;height: 10px;margin-right: 10px;display:inline-block"></span>支付金额：' +
							data[0].data +
							'<br/><span style="background: #F3D026;width: 10px;height: 10px;margin-right: 10px;display:inline-block"></span>访客数：' +
							data[0].data +
							'<br/><span style="background: #FF8534;width: 10px;height: 10px;margin-right: 10px;display:inline-block"></span>访问-支付转化率：' +
							data[0].data +
							'<br/><span style="background: #4CB5FE;width: 10px;height: 10px;margin-right: 10px;display:inline-block"></span>客单价：' +
							data[0].data
						);
					}
				},
				xAxis: {
					data: [ //x轴数据
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15',
						'09-15'
					],
					boundaryGap: false,//坐标轴两边留白策略 false 表示不留白
					//设置轴线的属性
					axisLine: {
						lineStyle: {
							color: '#4CB5FE',//x轴线的颜色
							width: 2 ,//这里是为了突出显示加上的  轴线的宽度

						}
					},
					//刻度相关设置
					axisTick :{//坐标轴刻度相关设置
						show :false //不显示刻度
					},
					axisLabel:{ //坐标轴label相关设置
						color:'#8F9394' //x轴的文字颜色设置
					}
				},
				yAxis: {
					// show:false,
					axisLine:{ //是否显示y轴
						show:false
					},
					axisTick:{//是否显示y轴刻度
						show:false
					},
					axisLabel :{//是否显示y轴文字
						show:false
					},
				},
				grid: {//画布的各个方向的距离
					left: '0%',
					right: '2%',
					bottom: '3%',
					containLabel: true
				},
				series: [//折线的相关设置
					{
						name: '销量',
						type: 'line',//折线图的类型  
						smooth: true,//折线是否顺滑
						lineStyle:{
							color:'#F5DA52' //折线的颜色
						},
						itemStyle:{
							color:'#2062E6',//折线点的颜色
							// borderWidth:4
						},
						symbol: 'circle',     //折线点 设定为实心点  
						symbolSize: 4,   //折线点 设定实心点的大小
						data: [5, 20, 36, 10, 10, 200, 5, 20, 36, 10, 10, 20, 5, 20, 360, 1000, 10, 20]
					},
				]
			});

The above is the relevant attribute settings used in the custom line chart.
