折线图

import * as echarts from 'echarts';const chartDom = document.getElementById('main');
const myChart = echarts.init(chartDom);
const option = {xAxis: {type: 'category',data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']},yAxis: {type: 'value'},series: [{data: [820, 932, 901, 934, 1290, 1330, 1320],type: 'line',smooth: true}]
};option && myChart.setOption(option);

折线图样式设置

在这里插入图片描述

饼图

import * as echarts from 'echarts';const chartDom = document.getElementById('main');
const myChart = echarts.init(chartDom);
const option = {tooltip: {trigger: 'item'},legend: {top: '5%',left: 'center'},series: [{name: 'Access From',type: 'pie',radius: ['40%', '70%'],avoidLabelOverlap: false,itemStyle: {borderRadius: 10,borderColor: '#fff',borderWidth: 2},// label: {//   show: false,//   position: 'center'// },emphasis: {label: {show: true// fontSize: 40,// fontWeight: 'bold'}},labelLine: {show: true},data: [{ value: 1048, name: 'Search Engine' },{ value: 735, name: 'Direct' },{ value: 580, name: 'Email' },{ value: 484, name: 'Union Ads' },{ value: 300, name: 'Video Ads' }]}]
};option && myChart.setOption(option);

饼图样式设置

在这里插入图片描述

标题设置 title:{ text: '男生', left:'center', bottom:'80', },

当有多个饼图时，可通过在series列表中添加center: ['50%','50%']改变饼图位置

柱状图

import * as echarts from 'echarts';var chartDom = document.getElementById('main');
var myChart = echarts.init(chartDom);
var option;option = {grid: {show: true},tooltip: {show: true},xAxis: {type: 'category',data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],axisLine: {lineStyle: {type: 'dashed'}}},yAxis: {type: 'value',splitLine: {lineStyle: {type: 'dashed'}}},series: [{data: [120, 200, 150, 80, 70, 110, 130],type: 'bar',itemStyle: {color: {x: 0,y: 0,x2: 0,y2: 1,colorStops: [{ offset: 0, color: '#4DD9A7' },{ offset: 0.5, color: '#80E4C0' },{ offset: 1, color: '#B6F1DD' }],global: false}}},{data: [120, 200, 150, 80, 70, 110, 130],type: 'bar',itemStyle: {color: {x: 0,y: 0,x2: 0,y2: 1,colorStops: [{ offset: 0, color: '#5EADF3' },{ offset: 0.5, color: '#98CAF6' },{ offset: 1, color: '#C4E0F9' }]}}}]
};option && myChart.setOption(option);
