An example of the Radar chart that doesn't have a fill color and has been set to use the trace effect (the Radar chart trace effect is much like the Line chart trace effect.
This goes in the documents header:<script src="RGraph.svg.common.core.js"></script> <script src="RGraph.svg.radar.js"></script>Put this where you want the chart to show up:
<div style="width: 600px; height: 500px" id="chart-container"></div>This is the code that generates the chart:
<script> data = [ [8,7,9,9,8,8,8], [5,8,5,6,3,5,6] ]; radar = new RGraph.SVG.Radar({ id: 'chart-container', data: data, options: { backgroundGridColor: '#ddd', colors: ['red','black'], linewidth: 2, labels: ['Bob','Reg','Dug','Lou','Joe','Kev','Jon'], tickmarks: 'filledcircle', tickmarksSize: 5 } }).trace(); </script>
