3.2 Customizing the installation

In order for JpGraph to work it is necessary to adjust the cache and TTF directory to suit the specific installation. By default the TTF directory is "/usr/X11R6/lib/X11/fonts/truetype/" and for the cache "/tmp/jpgraph_cache/". These are defined as PHP defines at the top of jpg-config.inc

Please make sure that PHP has write permissions to the cache directory if the cache feature should be used. If this is not the case a "Can't write file xxx.yyy" error will occur when a graph that uses the cache feature are generate. More information regarding the cache feature of JpGraph is available in the section Making sense of caching system in JpGraph
