Please read the Readme.txt file for a full description of what is needed to get these graphs working here
There have been a number of additions to the user-customisable variables in graphsconf.php. You may not need to change anything in graphsconf.php
to get the graphs working, but if your clientraw files and JPGraph directory are not in the default locations you will need to adjust the relative addresses
These graphs have been tested with both PHP5 and JPGraph 4.0.1
Be aware that JPGraph itself has some issues with PHP7 which have been reported so check their website for updates if you get any errors
