C#可配置数据源的SPC代码

In this article we can see in detail about how to create a simple SPC (Statistical Process Control) Cp,CPk Chart. I have been working on several automation projects. Nowadays automobile industry is interested in automated measuring machines to ensure quality and to compete in the global industry. The main part of any automation software is to get the accurate result with Quality check, for this purpose we use the SPC (Statistical Process Control) to find the quality result.
