uniapp微信小程序开发使用charts折线图， Ucharts需要隐藏折线图上面的label字段, 使用dataLabel:false实现。

dataLabel

<view class="charts-box">
			<qiun-data-charts :opts="optsLine" type="line" :chartData="chartDataLine" background="none" />
		</view>
optsLine: {
					"dataLabel": false,
					"color": ['#1A90FE', '#FA8C15', '#52C41B'],
					"legend": {
						"show": false,
						"position": "right",
