本文主要是介绍封装的charts使用 vue2，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
//组件
<template><div ref="chartRef" class="echart"></div>
</template><script>
import * as echarts from 'echarts'export default {data() {return {chart: null}},methods: {init() {if (!this.chart) {this.chart = echarts.init(this.$refs.chartRef)}},// 防抖debounce(fun, delay) {let timerreturn function () {if (timer) {clearTimeout(timer)}timer = setTimeout(() => {fun()}, delay)}},// 渲染图表setOptions(option) {if (!this.chart) returnthis.chart.setOption(option)},// 图表重绘setResize() {if (!this.chart) returnthis.chart.resize()}},mounted() {this.init()window.addEventListener('resize', () => this.debounce(this.setResize(), 500))},beforeDestroy() {if (!this.chart) returnthis.chart = null}
}
</script><style lang="scss" scoped>
.echart {width: 100%;height: 100%;min-height: 200px;
}
</style>
使用
<template><div><VueChart ref="lineChartRef" /></div>
</template><script>
import VueChart from './VueChart'const lineOption = {color: ['#317FF6', '#00FF7E'],grid: {top: '16%',left: '2%',right: '2%',bottom: '2%',containLabel: true},tooltip: {trigger: 'axis'},legend: {top: 10,right: 10,textStyle: { color: '#FFFFFF' }},xAxis: {type: 'category',axisLabel: {color: '#C2D7E8',fontSize: 12,rotate: 45},axisLine: {show: true,lineStyle: { color: 'rgba(255, 255, 255, .2)' }},axisTick: { show: false },data: ['星期一', '星期一', '星期一', '星期一', '星期一', '星期一', '星期一', '星期一', '星期一', '星期一', '星期一'],},yAxis: {type: 'value',name: '单位：家',nameTextStyle: { color: '#C2D7E8' },axisLabel: {color: '#C2D7E8',fontSize: 14},axisLine: {show: true,lineStyle: { color: 'rgba(255, 255, 255, .2)' }},splitLine: {lineStyle: {type: 'dashed',color: 'rgba(255, 255, 255, .2)'}}},series: [{name: '总收入',type: 'line',smooth: true,showSymbol: false,areaStyle: {// opacity: 0.8,color: {type: 'linear',x: 0,y: 0,x2: 0,y2: 1,colorStops: [{ offset: 0, color: 'rgba(49, 127, 246, .5)'},{ offset: 1, color: 'rgba(43, 254, 192, 0)' }],global: false}},data: [20, 120, 110, 90, 50, 30, 35, 40, 50, 100, 90]},{name: '纯收入',type: 'line',smooth: true,showSymbol: false,areaStyle: {// opacity: 0.8,color: {type: 'linear',x: 0,y: 0,x2: 0,y2: 1,colorStops: [{ offset: 0, color: 'rgba(43, 254, 192, .5)'},{ offset: 1, color: 'rgba(43, 254, 192, 0)' }],global: false}},data: [90, 50, 30, 35, 20, 120, 110, 90, 30, 35, 10]}]
}export default {name: 'Income',components: {VueChart},data() {return {}},mounted() {this.$refs.lineChartRef.setOptions(lineOption)}
}
