I cant get the line graph to work, it feels like i have tried everything, but its my first real try doing anything with javascript. Since its a school project i cant add the XML file, but i'm certain the calls for the variables are right. Heres the code, please help me.
This is all in <BODY> tag, and i have the proper code in <head> tag as well.

<div id="pulsgraf">This is just a replacement in case Javascript is not available or used for SEO purposes</div> <script type="text/javascript"> var xmlDoc=null; xmlDoc.async=false; xmlDoc.load( "G3.TCX" ) ; var x=xmlDoc.getElementsByTagName("Trackpoint" ); var pulsArray = new Array(); var metersArray = new Array(); for (i=0;i<x.length;i++){ pulsArray[ i ]=x[ i ].getElementsByTagName("Value" )[0].childNodes[0].nodeValue; metersArray[ i ]=x[ i ].getElementsByTagName("DistanceMeters" )[0].childNodes[0].nodeValue; } var myData = new Array(); for(b=0;b<x.length;b++){ mydata[ b ]= pulsArray[ b ], metersArray[ b ]; } var myChart = new JSChart('pulsgraf', 'line'); myChart.setDataArray(myData); myChart.draw(); </script>
