目前有一个关于绘图功能如何使用的文档，主要是面向普通用户的
https://github.com/wh201906/SerialTest/blob/master/doc/tutorials/plot/plot_zh_CN.md
关于内部具体实现目前没有相关文档
以当前master分支上的最新提交717a69a 为例：
rawReceivedData只是用来存储已接收的数据，用于“数据”选项卡当中的16进制显示和导出功能
程序中UI的更新是通过MainWindow::updateRxUI()来完成的，当中调用了plotTab->newData(RxUIBuf)来给“绘图”选项卡提供数据。

我修改了RxUIBuf的数值，发现绘图功能已经能成功绘制图像了。这里有还一个问题，我需要绘制的图像是一个连续的sin波形，也就是说传入RxUIBuf的数据将会是256个连续的数据，我要怎么修改让绘图能够成功识别呢？按照数据分隔符","来分割的话，256个连续数据会被当成256个不同的图例数据吧？

搞定了，发送数据的时候把分隔符全改成数据帧分隔符就行。感谢大佬的帮助。
