EEP Plot files - Grouhcraft/EEGAnalysis GitHub Wiki

EEP Plot files (_.eep_ extension) are _xml_ files.

The XSD can be found here
Basicaly, the root node <plot> contains the nodes <metas> and <code>.

• <metas> contain the name of the plot, along with the description of the axis
• <code> may contain user settings/variables and always contain a <node> where one should write the javascript code of the plot.

Sample eep:

 <? xml version="1.0" encoding="UTF-8"?>
 <plot xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="plot.xsd">
 	<metas>
 		<name>Second test</name>
 			
 		<axis type="x" unit="s">Temps</axis>
 		<axis type="y" unit="">Amplitude Log10</axis>
 	</metas>
 	<code>
 		<script type="text/javascript" main="tameme">
 		<![CDATA[
 		var shift = 39;
 		function tameme(data) { 
 			for(var i=0; i<data[1].length; i++) {
 				data[1][i] = log10(data[1][i]);
 			}
 			return data; 
 		} 
 		function log10(val) {
 			return Math.log(val) / Math.log(10);
 		}
 		]]>
 		</script>
 	</code>
 </plot>

The main function is set by the main attribute of the <script> tag.
This function is then called with a data object as parameter.
the data object is a 2-d number array representing the raw values of the signal, where index 0 is X, index 1 is Y, and index 3 is Z if needed.
