Funnel

A Funnel chart is ideal to display how Input/Output (I/O) reduces with time.

If the top of the chart shows 100% of, for example sales prospects, the bottom could represent Invoiced Sales, and be more reduced than the prospects. That gives it a funnel shape, and can show as many steps as desired in between.

Setting Description
Labels & Tooltips  
Show Percentage of Total When enabled, it allows you to display the total of each group on the chart as percentage. For more accuracy, you can use the Decimal Places option.
Funnel Options  
Dynamic Height

When activating the dynamic height, the steps of the funnel have an area proportional to their value, otherwise, they have the same height.

Dynamic Slope

The Dynamic Slope option will make the last step a rectangle and adjust the funnel slope from the top to the bottom.

Neck ratio

If Dynamic Slope is deactivated you can set this ratio to determine the slope.
