A Funnel Series illustrates how a value changes during a process, with bar widths representing the value at each stage and drop-offs denoting the change between them.
 Simple Funnel Copy Link  
To create a Funnel Series, use the funnel series type.
{
    series: [
        {
            type: 'funnel',
            stageKey: 'group',
            valueKey: 'value',
        },
    ],
}
In this configuration:
stageKeydefines the stages which are used for the bars of the funnel.valueKeyprovides the numerical values which determine the width of each bar.
 Horizontal Funnel Copy Link  
To create a horizontal Funnel Series, set the direction to horizontal.
{
    direction: 'horizontal',
}
 Segmented Funnel Copy Link  
A segmented funnel does not draw the drop offs between the stages.
To disable the drop offs, set enabled to false in the dropOff configuration.
{
    dropOff: {
        enabled: false,
    },
}
 Customisation Copy Link  
{
    fills: ['#5090DC', '#FFA03A', '#459D55', '#34BFE1'],
}
In this configuration:
- The fills for each stage are defined in the 
fillsarray. - The drop offs use an opacity of the same fills. This can be changed in the drop off options.
 - The Funnel Series is reversed by providing the data items in the reverse order.
