Creating waterfall charts

The waterfall chart is suitable for illustrating how an initial value is affected by intermediate positive and negative values. The starting and the final values are represented by whole bars, and intermediate values by floating bars. You can also show subtotals in the chart.

You can create a waterfall chart on the sheet you are editing.

In a waterfall chart you need to use one measure for each bar in the chart. The order of the measures defines the order of the bars in the chart. For each measure, you need to define how it affects the previous value. You can add up to 15 measures in a waterfall chart.

Do the following:

1. In a sheet, click to add a new visualization.
2. Under Visualization, select Waterfall chart.

3. Add the first measure.

   This is the first bar of the chart. By default, it will use the measure operation Add, and show a positive value.

4. Add a second measure.

   This is the second bar of the chart. If you want to show this measure as a negative contribution, click Advanced options and in the properties panel, change Measure operation to Subtract.

5. Continue to add measures, setting Measure operation to Add or Subtract depending on how you want them to contribute.

6. Add subtotals. There are two ways of adding subtotal bars to the chart:

   • If you have a data field containing subtotal data, add a measure with the subtotal data and in the advanced edit mode properties panel, select Subtotals as Measure operation.
   • If you don't have a data field containing subtotal data, you can add an automatically calculated subtotal by selecting the Subtotals check box of the measure in the advanced edit mode properties panel, before where you want the subtotal bar.

When you have created the waterfall chart, you may want to adjust its appearance and other settings in the properties panel.

Defining your measures

You can use the Measure operation option of each measure in the advanced edit mode to set how it affects the previous value.

• Add

  The measure value adds to the previous bar. If this is the first measure, a whole bar is shown starting at 0.

• Subtract

  The measure value subtracts from the previous bar.

  Information noteIf the data already contains a negative sign, the result of subtraction will be a positive change.

• Subtotals

  The measure value is considered a subtotal.

  Tip noteIf you do not have sub-totals as a field, you can add subtotals automatically by enabling Subtotals in the measure before you want the subtotal.

In the waterfall chart shown above, the first bar, Sales, is defined as Add. The second bar, Sales cost, is defined as Subtract, and the third bar, Sales margin, is defined as Subtotals.
