<script src="RGraph.common.core.js"></script> <script src="RGraph.common.dynamic.js"></script> <script src="RGraph.common.tooltips.js"></script> <script src="RGraph.rose.js"></script>Put this where you want the chart to show up:
<div style="padding: 50px"> <canvas id="cvs" width="450" height="450" style="border: 1px solid #ddd">[No canvas support]</canvas> </div>This is the code that generates the chart:
<script> new RGraph.Rose({ id: 'cvs', data: [[15,6],[14,3],[15,5],[15,5],[15,1],[16,5],[16,5]], options: { gutterTop: 35, gutterBottom: 35, gutterLeft: 35, gutterRight: 35, variant: 'non-equi-angular', backgroundGridColor: 'rgba(0,0,0,0)', backgroundAxesColor: 'rgba(0,0,0,0)', labelsAxes: '', colorsAlpha: 1, colors: ['red','blue','green','pink','black','yellow','cyan','brown'], colorsSequential: true, strokestyle: 'rgba(0,0,0,0)', labels: ['Richard','Robert','Rico','Ray','Raife','Ryan','Roland'], tooltips: ['Richard','Robert','Rico','Ray','Raife','Ryan','Roland'], ymax: 16 //animationRoundrobinRadius: false, } }).roundRobin({radius: false}); </script>
