<p>After the image has been created, the graph function uses printf
together with this format string to create output similar to the PRINT

right and bottom border, <code>GRID</code>, <code>MGRID</code> for the major grid, <code>FONT</code> for
the color of the font, <code>AXIS</code> for the axis of the graph, <code>FRAME</code> for the

+line around the color spots, and finally <code>ARROW</code> for the arrow head pointing
up and forward. Each color is composed out of three hexadecimal numbers
specifying its rgb color component (00 is off, FF is maximum) of red, green
and blue. Optionally you may add another hexadecimal number specifying the

<p>Zoom the graphics by the given amount. The factor must be > 0</p>

<p>Use Times for the title: <code>--font TITLE:13:Times</code></p>
<p>If you do not give a font string you can modify just the sice of the default font:

<p>There are 2 render modes:</p>
<p><strong>normal</strong>: Graphs are fully Antialiased (default)</p>
<p>You need at least one <strong>DEF</strong> statement to generate anything. The
other statements are useful but optional.
See <a href="././rrdgraph_data.html">the rrdgraph_data manpage</a> and <a href="././rrdgraph_rpn.html">the rrdgraph_rpn manpage</a> for the exact format.</p>
