<p>Prior to ver. 3.5, bitmap fonts are used by default which can specified from <code class="code">FF_FONT0</code> to <code class="code">FF_FONT2</code>. From version 3.5, default fonts are now set to one of the open-source TrueType DejaVu font (<code class="code">FF_DV_SANSSERIF</code>, DejaVuSans.ttf). This TrueType font is included in JpGraph source code (src/fonts), and there is no need to specify font for this one.</p>
<p>You can change default font family by changing <code class="code">FF_DEFAULT</code> defined in <code class="filename">jpgraph_ttf.inc.php</code>. You have to prepare your own font file as well in order to use another font.</p>
<p>If Freetype library is not usable in your PHP configuration, original BITMAP font will be used for compatibility.</p>
<p>All graph objects that uses text allows you to specify the font to be used by
calling a <code class="code">SetFont()</code> method and specifying three parameters.</p>
