Pyramid Chart

Pyramid chart is just a reversed Funnel chart with no neck. To make this chart, you simply create AmFunnelChart and set “rotate”:true. By default, the height of a slice represents it’s value. However you might want the area of a slice to represent value. In this case you should add “valueRepresents”:”area” property to the chart’s config.
