Summary of statistical charts using owc

In a recent project, we need to perform statistical analysis on the Data. Therefore, we first thought of Microsoft's owc and encapsulated the owc operations. In Program Is much more convenient.

Let's take a look at it first:

Before using this class, you must first reference the owc DLL!
