<v-chart v-if="staticShow" :option='options' :update-options="{notMerge: true}" @click="handleClick" autoresize/> 词云 多次刷新数据会重叠
时间: 2023-07-06 13:33:09 浏览: 46
问题可能出在你的词云组件在多次刷新数据后没有清空已有的图形。你可以尝试在每次更新数据之前,先清空已有的图形,再重新绘制新的图形。你可以在更新数据的时候,调用echarts实例的`clear`方法,清除已有的图形,然后再调用`setOption`方法,重新绘制新的图形。具体实现可以参考下面的代码:
```javascript
// 获取echarts实例
let chartInstance = this.$refs.chartInstance;
// 清空已有的图形
chartInstance.clear();
// 设置新的数据
chartInstance.setOption(options);
```
这样就可以保证每次刷新数据的时候,都不会出现图形重叠的问题了。

需要注意的是,Element UI的CSS样式需要在HTML文件中引入。此外,上述代码中的`activeName`、`search`、`filterTableData`、`handleEdit`和`handleDelete`需要在JavaScript中定义和实现。
翻译这段代码 <el-form-item label="所属机构" prop="orgId"> <el-tree-select v-model="formData.orgId" :data="organizationData" node-key="id" check-strictly :render-after-expand="false" :props="{label: 'text'}" @node-click="handleClick" :default-expanded-keys="defaultExpandedKeys" /> </el-form-item>
这段代码是一个Vue.js的模板代码片段,用于渲染一个包含表单项的组件。下面是代码的翻译:
```html
<el-form-item label="所属机构" prop="orgId">
<el-tree-select
v-model="formData.orgId"
:data="organizationData"
node-key="id"
check-strictly
:render-after-expand="false"
:props="{label: 'text'}"
@node-click="handleClick"
:default-expanded-keys="defaultExpandedKeys"
/>
</el-form-item>
```
这段代码渲染了一个表单项,标签名为"所属机构",属性名为"orgId"。在这个表单项中,使用了 `el-tree-select` 组件来展示一个树形下拉选择框。以下是对各个属性和事件的解释:
- `v-model`:绑定了表单项的值到 `formData.orgId`,当选择发生变化时,该值也会相应地更新。
- `:data`:指定了树形下拉选择框展示的数据源,数据源为 `organizationData`。
- `node-key`:指定了数据源中每个节点的唯一标识字段为 "id"。
- `check-strictly`:启用严格的多选模式。
- `:render-after-expand`:设置为 `false`,表示节点展开后不延迟渲染子节点。
- `:props`:设置了节点的显示文本字段为 "text"。
- `@node-click`:指定了在节点被点击时触发的事件处理函数为 `handleClick`。
- `:default-expanded-keys`:指定了默认展开的节点的 `id` 列表为 `defaultExpandedKeys`。
