Convert a pie chart from PHPExcel to Excel

PHPExcel is a powerful tool for processing Excel files. I have a report with a pie chart, which needs to be converted to Excel. PHPExcel has a related example. After referring to and modifying it, this effect is achieved,

Allows you to generate and download an Excel file during click Download, and generate a pie chart in the Excel file.

In this example, we made two major changes:

1. retrieve data from the MySQL database.

2. added the Chinese file name in Some browsers, such as IE, to solve the problem of garbled names during download.

The PHP report is as follows:

Therefore, it is mainly calculated in the code. On a non-Windows Server, generation fails.
