uniapp_使用echarts

从 npm 获取echarts

npm install echarts --save

页面使用：（里面index.vue页面有示例）

引入：

<template>
    <view class="content">
        <view style="width: 750rpx;">
            <yh-echarts @myChart="myChartData" :option="optionData1" style="height: 400rpx;"></yh-echarts>
        </view>

        <!-- 如果用两个可以去掉@myChart 传一个实例就可以了 -->
        <view style="width: 750rpx;">
            <yh-echarts :option="optionData2" style="height: 400rpx;"></yh-echarts>
        </view>
    </view>
</template>
