JpGraph and TCPDF are used to dynamically generate graphic PDF files.

Basic Environment: PHP5

Because jpgraph depends on the GD library, you need to check whether the GD library is installed before using jpgraph. (The GD library is an extension library for php to process graphics. The GD library provides a series of APIS for processing images. You can use the GD library to process images or generate images .)

How do I check whether the GD library is installed? The method is as follows:

Create a file in the root directory of the apache website (/var/www by default), such as phpinfo. php. The content is as follows:

<% Php
Phpinfo ()
%>

Access this php file through a browser, such as http: // server_ip/phpinfo. php. If the following content is displayed, the GD library has been installed. If not, install the GD library first.

Jpgraph

1. Download jpgraph

Http://jpgraph.net/download

2. Install jpgraph

Decompress the downloaded jpgraph and place it in the directory accessible to php. Here, it is/usr/share/php5/, and a soft connection is established under/usr/share/php5 to point to the src directory of the jpgraph library.

Ln-s jpgraph-3.5.0b1/src jpgraph

Change the php configuration file/etc/php5/apache2/php. ini and/etc/php5/cli/php. ini, locate the include_path item, uncomment and add/usr/share/php5 to the search directory, for example:

Include_path = ".:/usr/share/php5"
