<h2>Database Interface Script</h2>
|
|
|
|
<p>Here the graphing software is instructed to dynamically read data from a CSV file.</p>
|
|
<p>This method allows you to graph data dynamically straight from a CSV file.</p>

height="400" />

<p>The graph above is produced using the "Data Interface Script" method with the following IMG tag:-</p>

<p>With this method the graphing software calls the interface script at runtime and reads the output of the script
|
|
in the same way that it would read the data from a flat file. This method allows data to be dynamically produced
|
|
and plotted in real-time.</p>
|
|
|
|
<p>The settings and styles are set from the information contained in the file:-</p>

<p>If the graph above does not display then see the <a href="../../documentation/troubleShooting.htm">Troubleshooting guide</a> for details on how to resolve the problem.</p>
|
|
|
|
<p>If the graph above does display but no data is shown then the most likely cause is that the graph is having trouble
|
|
connecting to the database server. Ensure that the '<a href='../../sampleApplication/index.php'>Sample Application</a>' has been set up
|
|
with the correct DB User credentials.</p>
|
|
<p>If you have not yet set up the Sample Application then
|
|
you can do so <a href='../../sampleApplication/index.php'>here</a>.</p>
