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 () { var 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>
You can use these properties to control how the Funnel chart appears. You can set them by using the Set() method. Eg:
myFunnel.Set('name', 'value');
chart.gutter | The gutter of the chart. This is the whitespace area around the chart. Default: 25 |
