Typical application of PHP graphics and images-application of common images (Statistical Chart)

Based on GD library and jpgraph Library

Note: For specific usage of the jpgraph class library, refer to the documentation on the official website:Http://jpgraph.net/download/manuals/classref/index.html

ForCode, The jpgraph file paths may be different. I introduced them according to the path where my own files are stored. You can change it on your own
