<P> In order for JpGraph to work it is necessary to adjust the cache and
|
|
|
30 |
TTF directory to suit the specific installation. By default the TTF
|
|
|
31 |
directory is "/usr/X11R6/lib/X11/fonts/truetype/" and for the cache
|
|
|
32 |
"/tmp/jpgraph_cache/". These are defined as PHP defines at the top of<I>
|
|
|
33 |
jpg-config.inc.php</I></P>
|
|
|
34 |
<P> Please make sure that PHP has write permissions to the cache
|
|
|
35 |
directory if the cache feature should be used. If this is not the case
|
|
|
36 |
a "Can't write file xxx.yyy" error will occur when a graph that uses
|
|
|
37 |
the cache feature are generate. More information regarding the cache
|
|
|
38 |
feature of JpGraph is available in the section<I> Making sense of
|
|
|
39 |
caching system in JpGraph</I></P>
