<p>All configuration of the library is done in the file
<code class="filename">jpg-config.inc.php</code>. Each option in the file is extensively
documented in <a class="xref" href="apl.html" title="Appendix L. The JpGraph configuration file">Appendix L. <i>The JpGraph configuration file</i></a> Here we will only cover the most important
configuration that it likely to have to be customized in order to successfully run
the library.</p>
<p>
</p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3>
<p>All configuration settings comes with default values that should in normal
cases be enough for a "standard" system. However for a production system you
might want to fine tune this according to your specific system setup.</p>

<p>During development (and to some extent even on a production server) it
might be necessary to adjust some parameters in your
<code class="filename">php.ini</code> file. For more on this see <a class="xref" href="ch03s03.html" title="Installing the library">Installing the library</a></p>

<p>There are three categories of directory paths that can be specified. The
categories are:</p>
<p>
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
<p>Font directories, this we already touched upon in <a class="xref" href="ch03s04.html#sec1.getting_add_fonts" title="Configuring TTF fonts">Configuring TTF fonts</a>. </p>
</li><li class="listitem">
<p>Cache directory, the cache feature of the library is extensively
discussed in <a class="xref" href="ch09.html" title="Chapter 9. Using the JpGraph cache system">Chapter 9. <i>Using the JpGraph cache system</i></a>. The important thing to notice
here is that whatever directory you chose to use as a cache
directory it must be a directory that is writable for the process
running PHP (normally the HTTP server process, e.g. Apache)</p>
</li><li class="listitem">
<p>CSIM Cache directory (if CSIM cache feature is used). CSIM stands
for Client Side Image Maps and is a way to construct client side
drill down charts. (Today this is the only inpractice used image
mapping method but it is also possible to have Server Side Image
Maps).</p>
