Funnel chart
Funnel charts are often used to represent stages in a sales process and show the amount of potential revenue for each stage. 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. The height and width of a neck is controlled by neckWidth and neckHeight properties.
Funnel chart with patterns
Click on PATTERNS theme above the chart – you will see that our Funnel chart supports patterns. There are several pre-built patterns in our package or you can easily build your own fancy patterns and use them with our charts.
