RGraph: Funnel chart documentation

This is a funnel chart. It can be used to illustrate stages of a sales or order fulfillment process, and in doing so highlight any bottlenecks or steps where large amounts of customers are lost.

The example file is here. 

<script>
    window.onload = function ()
    {
        funnel = new RGraph.Funnel('funnel1', [100,45,45,26,21,5]);
        funnel.Set('chart.text.boxed', false);
        funnel.Set('chart.title', 'Leads through to sales');
        funnel.Set('chart.labels', ['A', 'B', 'C', 'D', 'E', 'F']);
        funnel.Set('chart.shadow', true);
        funnel.Draw();
    }
</script>
