Development of catering System Based on winform "Implementation of three-dimensional pie chart (with source code example )"

This article describes how to implement the effect of a three-dimensional pie chart in the "catering system" developmentCodeAnd the attached example, I believe that friends in need can easily use! Project, as follows:

The system. Drawing. piechart. piechartcontrol control is implemented. The piecharthelper class is as follows:
