When our software requires various pie charts and bar charts to represent data, we may think of using graphical controls or third-party controls in Offices, but most of the third-party controls need to be registered now, some free controls have Developer tags. However, graphical controls using Offices cannot be well controlled in the program, and the ease of use is also low, so here I will show how to use GDI + in C # to connect the

In the course of data warehouse and data mining today, the teacher is always proposing bar charts, pie charts, and so on, We also told us to come back and draw a few more. Alas, it's annoying, Come back in the evening and have a whimsy. Why don't I write a pie chart generator by myself, Haha, just do it, so we have
