We will start with a simple line graph.
</p><pre class="programlisting">&lt;?php
//Include the code
require_once 'phplot.php';

//Define the object
$plot = new PHPlot();

//Define some data
$example_data = array(
     array('a',3),
     array('b',5),
     array('c',7),
     array('d',8),
     array('e',2),
     array('f',6),
     array('g',7)
);
$plot-&gt;SetDataValues($example_data);

//Turn off X axis ticks and labels because they get in the way:
$plot-&gt;SetXTickLabelPos('none');
$plot-&gt;SetXTickPos('none');

//Draw it
$plot-&gt;DrawGraph();
</pre><p>

</p><p>

And that's it! What we get is the following graph:

</p><div class="informalfigure"><div class="mediaobject"><img src="examples/qs1.png" alt="Simple line graph" /></div></div><p>
</p><p>
That's a great start, but now we would like to specify the width and height
of the image, and add some titles.
