First of all, set the width and height of a box! You can't use percentages, only px
Then draw the chart in methods and generate a simple chart through the setOption method,
Then mount the method to the hook function mounted() to call
<template>
<div>
<div id="myChart" :style="{ width: '400px', height: '300px' }"></div>
<div id="myTry" :style="{ width: '400px', height: '300px' }"></div>
</div>
</template>
<script>
export default {
name: "hello",
data() {
return {
msg: "Welcome to Your Vue.js App",
};
},
methods: {
drawLine() {
// 基于准备好的dom，初始化echarts实例
let myChart = this.$echarts.init(document.getElementById("myChart"));
// 绘制图表
myChart.setOption({
title: { text: "商场跳楼价" },
tooltip: {},
xAxis: {
data: ["衬衫", "羊毛衫", "雪纺衫"],
},
yAxis: {},
series: [
{
name: "销量",
type: "bar",
data: [5, 20, 36],
},
],
});
},
try() {
let myTry = this.$echarts.init(document.getElementById("myTry"));
myTry.setOption({
xAxis: {
type: "category",
data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"],
},
yAxis: {
type: "value",
},
series: [
{
data: [820, 932, 901, 934, 1290, 1110, 1320],
type: "line",
smooth: true,
},
{
data: [900, 951, 901, 852, 1520, 1330, 1200],
type: "line",
smooth: true,
},
],
});
},
},
mounted() {
this.drawLine();
this.try();
},
};
</script>
Modify the style of the chart:
To modify the width of the histogram, you only need to add the width of barWidth.
series: [
{
data: [40, 50, 30],
type: "bar",
barWidth : 30,//柱图宽度
},
],a simple pie chart
Bar spacing
There are two types of bar spacing, barGap and barCategoryGap .
barGap is the gap between two small graphs in a bar chart barCategoryGap is the gap between each abc can use a percentage
