实现echarts图提示框自定义样式,最重要的是给tooltip加一个自定义class,下面是我写的例子:
- tooltip: {
- trigger: "axis",
- axisPointer: {
- type: "line",
- },
- className: "custom-tooltip-box",
- formatter: function (params) {
- return `
- ${params[0].name}年
-
- 缺材飞机数量:
- ${params[0].value}
-
- `;
- },
- }
- ::v-deep .custom-tooltip-box {
- padding: 0 !important;
- border: none !important;
- background-color: transparent !important;
- // 给子盒子自定义样式
- .custom-tooltip-style {
- width: 25rem;
- min-height: 12rem;
- background: url("../../../../assets/images/tooltipBg.webp") no-repeat center
- center;
- background-size: 100% 100%;
- color: #fff;
- display: flex;
- flex-direction: column;
- padding: 1rem 2rem;
- font-size: 1.6rem;
- .span {
- display: flex;
- justify-content: space-between;
- margin-top: 0.5rem;
- :last-child {
- font-weight: 600;
- font-size: 1.8rem;
- }
- }
- }
- }
该实例提示框背景是切的图片,内容通过formatter进行配置,样式上通过赋予className并在style标签中编写,实现如下效果:

(该tooltip自定义样式适用于所有的echarts图,如折线图、柱状图、饼图)
