我写的是一个工程数据检测，然后画出数据曲线的实例，Demo 中的数据为随机生成的数据，由于我没有做过控件，所以在 DataCurve.pas 只定义了一个多线程的类，没有做成控件。-I wrote an engineering data detection, and then draw an example of curve data, Demo data for the randomly generated data, because I have not done control, so only DataCurve.pas defines a type of multi-threaded, there is no made control.
