You can test PHPlot with any of the examples in <a class="xref" href="examples.html" title="Chapter 5. PHPlot Examples">Chapter 5, <em>PHPlot Examples</em></a>,
or by entering this minimal script into a file called (for example)
<code class="filename">plottest.php</code>.
</p><pre class="programlisting">&lt;?php
require 'phplot.php';
$data = array(array('', 10), array('', 1));
$plot = new PHPlot();
$plot-&gt;SetDataValues($data);
$plot-&gt;SetTitle('First Test Plot');
$plot-&gt;DrawGraph();
</pre><p>
Access this script through your browser, and you should see a very simple
plot. Note: Since PHPlot returns image data, not text, you will generally
not see error messages in the output. If a script using PHPlot has a
syntax error, or calls an undefined function, you will get a blank page
returned, and you will probably have to check the web server error log
for the reason.
You might find that debugging your PHPlot applications is easier using
the PHP CLI (command line interface),
as described at the start of <a class="xref" href="examples.html" title="Chapter 5. PHPlot Examples">Chapter 5, <em>PHPlot Examples</em></a>.
</p><p>
If you are installing PHPlot for use by some web application (rather than
to develop your own applications), proceed with that application's setup
instructions. If you want to develop your own applications using PHPlot, you
can start by looking at some of the examples in <a class="xref" href="examples.html" title="Chapter 5. PHPlot Examples">Chapter 5, <em>PHPlot Examples</em></a>,
or go right to the introductory material in <a class="xref" href="starting.html" title="Chapter 2. Getting Started with PHPlot">Chapter 2, <em>Getting Started with PHPlot</em></a>.
Experienced programmers may want to skip right to <a class="xref" href="concepts.html" title="Chapter 3. PHPlot Concepts">Chapter 3, <em>PHPlot Concepts</em></a>
to learn about PHPlot concepts and features in depth.
