<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>
<img src="../../graph/vertical-cylinder-graph.php?
data=../demo/examples/data/csvdataScript.php&
config=../demo/examples/data/csvConfig.php"
width="700"
height="400" />
<p>The graph above is produced using the "Data Interface Script" method with the following IMG tag:-</p>
<textarea class="jpcodeblock" style="width: 600px;">
<img src="../../graph/vertical-cylinder-graph.php?
data=../demo/examples/data/csvdataScript.php&
config=../demo/examples/data/csvConfig.php"
width="700"
height="400" />
</textarea>
<p>The graph data is produced by the interface script and read by the graphing software at runtime:-</p>
<textarea class="jpcodeblock" style="width: 600px;">
./jpowered/demo/examples/data/csvdataScript.php
/*
* read the csv file
*/
$csvdata = file('csvData.csv');
$first = TRUE;
$dataCount = 1;
/*
* process each row of the
* csv file
*/
foreach ($csvdata as $datarow)
{
if ($first) // ignore the first header row
{
$first = FALSE;
}
else
{
/*
* extract the temperature value
* from each row and write out
* the data parameter
*/
$dataelements = explode(',',$datarow);
if (isset($dataelements[1]))
{
$dataelements[1] = (float)$dataelements[1];
print 'data'. $dataCount .'series1: ' . $dataelements[1] . PHP_EOL;
$dataCount++;
}
}
}
</textarea>
<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>
<textarea class="jpcodeblock" style="width: 600px;">
./jpowered/demo/examples/data/csvConfig.php
</textarea>
<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>
