设置数据条颜色（推荐）

let yData = [{value: 500,time: '2012-11-12',itemStyle: //设置数据条颜色{normal: { color: 'red' }}},{value: 454,time: '2020-5-17'},{value: 544,time: '2022-1-22'},{value: 877,time: '2013-1-30'}, {value: 877,time: '2012-11-12'}]

---

设置数据条颜色2 （不推荐）

itemStyle:{normal: {color: pamars => {let colorList = ['red', 'yellow', 'blue', 'green', 'pink']return colorList[pamars.dataIndex]}}}

---

设置轴的宽度

 series:   [{name: '图例',type: 'bar',//图表类型data: yData,//图标数据barWidth: 25//数据条宽度}]

完整配置

 draw() {let xData = ['华为', '小米', '苹果', '三星', '酷派']let yData = [{'value': '500','time': '2012-11-12'},{'value': '454','time': '2020-5-17'},{'value': '544','time': '2022-1-22'},{'value': '877','time': '2013-1-30'}, {'value': '877','time': '2012-11-12'}]const myChart = this.$echarts.init(this.$refs.myChart)//初始化对象myChart.setOption({ //参数配置项legend: {show: true, //是否展示图例 }, xAxis://设置x轴数据{type: 'value'//设置数据}, yAxis://设置y轴数据{data: xData,type: 'category'}, series:[{name: '图例',type: 'bar',//图表类型data: yData,//图标数据barWidth: 25,//数据条宽度itemStyle:{normal: {color: pamars => {let colorList = ['red', 'yellow', 'blue', 'green', 'pink']return colorList[pamars.dataIndex]}}}}]})}
