v-show切换<mpvue-echarts>时存在问题

分类：uni-app

在hello uni-app上的echarts示例中即可重现此问题,只可以显示第一个echarts图表
下面代码为hello uni-app中的代码，稍加改造
<button class="update-btn" type="primary" size="mini" @click="current = !current">切换</button>
<view class="canvasView" v-show="current">
<view class="canvas-bar">
<view class="title">饼图示例</view>
<button class="update-btn" type="primary" size="mini" @click="updatePie">修改饼状图数据</button>
</view>
<mpvue-echarts :echarts="echarts" :onInit="pieInit" canvasId="pie" ref="pieChart" />
</view>
<view class="canvasView" v-show="!current">
<view class="title">折线图示例</view>
<mpvue-echarts :echarts="echarts" :onInit="lineInit" canvasId="line" ref="lineChart" />
</view>
