For a standard waterfall, set the desired hierarchy and members on categories. The chart will then display each value as a waterfall accumulating in a total column/bar.
Right-click on a waterfall column/bar to access options:
- Total: set the category as a total, plotting from the category axis
- Subtotal: plots from the last total
- Custom subtotal count: if the category is set as a subtotal, you can set a custom count for how many previous categories it is the total for. If this is unset it subtotals from the previous total/subtotal (see example below)
- Negate: plot the categories in the negative direction
- Auto total after: add a total category after the selected one
- Auto total title: change the category label of the auto title. The default is "Total"
Members can be configured as totals/subtotals/expenses automatically using Business Rules.
Custom Subtotal Count
In the example below, Operating Expenses is set as a subtotal on the Business Rules sheet. Because 'Standard Cost of Sales' and 'Variances' aren't child members of 'Operating Expenses', and the previous total/subtotal is for Net Sales, the subtotal lines don't line up correctly. We instead want the line to connect from the Labour Expenses category.
When we use the right-click option to set the custom subtotal count, in this case set it to 10, then the subtotal is displayed correctly.
Variance waterfall charts display the members on categories as totals. The variance between each on can then be split up by whatever is on the 'Split Categories by'. This can either be the same hierarchy, or a new hierarchy can be placed in this area.
