手写的简单折线图，可以参考一下，拿过去重新改改 通过增加数据，折线图会按时间依次绘制折现。 用的上的可以给个star支持一下，未来开源更多代码给大家参考
Simple line drawings, dynamic line charts
Handwritten simple line chart, you can refer to it, take it over to change By adding more data, the line chart is discounted over time.
#Use of the top can give a star support, the future open source more code for your reference
