Installing and Configuring PHP JpGraph on Linux
Last updated:Installation and configuration
download the project file here (most recent release as of 12 Sep 2012)
extract the file:
tar -zxvf jpgraph-3.5.0b1.tar.gz
copy the src directory into your web project. Let's assume you have created a PHP project at /var/www/my_project
sudo cp jpgraph-3.5.0b1/src/ /var/www/my_project/ -r
now cd over to your project:
cd /var/www/my_project
rename the src directory:
sudo mv src jpgraph
and set liberal permissions to avoid problems at this stage:
sudo chmod 777 jpgraph -R
now let's correct some bugs in the project:
head over to jpgraph/gd_image.inc.php and comment out this line: (on my version [jpgraph-3.5.0b1] it's line 110)
// JpGraphError::RaiseL(25128);//('The function imageantialias() ...
Now we may need to install some Fonts which sometimes aren't available on Linux.
The easiest way to get the fonts is to go to a Windows machine and go to C:\Windows\Fonts\Arial and copy all those .ttf files into /usr/share/fonts/truetype/
Done.
Troubleshooting
You can start using it. I recommend trying out some of the examples... Some of them probably won't work due to reasons I don't understand but, from my experience, it will help if, in the includes, you specify an absolute path rather than the relative pathing that comes in the Examples.
I think it might have something to do with the way they created a directory inside Examples which is a symlink to its parent directory... not sure how that is supposed to work.. The whole thing is a bit messy if you ask me. I'd use Highcharts if I could choose but for this project specifically I need to use JpGraph.. Anyway. Good luck.
Oh Yeah. If you run into other font problems you just do same process you did for Arial again.
