柱状图是比较常用的图形结构，所以我先收集一些精美的柱状图
一、柱状图：设置圆角和颜色
<template><div class="box" ref="chartDom"></div>
</template>
<script setup>
import { ref, onMounted } from "vue";
import * as echarts from "echarts";
let chartDom = ref(null); //注意变量名 和 ref名字要对应
onMounted(() => {initChart();
});const initChart = () => {var myChart = echarts.init(chartDom.value);var option = {tooltip: {// 鼠标悬浮提示数据trigger: "axis",backgroundColor: "rgba(32, 33, 36,.7)",borderColor: "rgba(32, 33, 36,0.20)",borderWidth: 15,textStyle: {// 文字提示样式color: "#fff",fontSize: "12",},axisPointer: {// 坐标轴虚线type: "cross",label: {backgroundColor: "#6a7985",},},},// },grid: {// 控制图表的位置left: "5%",right: "5%",top: "18%",bottom: "5%",containLabel: true,},xAxis: {axisLabel: {// X轴线 标签修改textStyle: {color: "white", //坐标值得具体的颜色fontSize: "10",},},data: ["A", "B", "C", "D", "E", "F"],},yAxis: {axisLabel: {// y轴线 标签修改textStyle: {color: "white", //坐标值得具体的颜色},},},series: [{data: [2549, 12421, 2637, 3146, 15189, 9562],type: "bar",barWidth: "48%", //调整柱状图宽度itemStyle: {normal: {/*--------设置柱形图圆角 [左上角，右上角，右下角，左下角]-------------*/borderRadius: [12, 12, 0, 0],/*--------设置柱形图渐变色 -------------*/color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{offset: 0,color: "rgba(0,244,255,1)",},{offset: 1,color: "rgba(0,77,167,1)",},]),},},},],};option && myChart.setOption(option);
};
</script><style scoped>
.box {width: 24vw;height: 60vh;background-color: #031a67;
}
</style>
