Waterfall charts have initial and final value columns with floating columns in between,
demonstrating negative and positive values with an impact on the initial and final values.
The most common use case for a waterfall chart is displaying three total columns with the changes between. Often these are three different years with profit and loss comparison and a midpoint total column.
Waterfall charts include the option to change the color of the columns representing Positive Change and Negative Change. Select the series from the drop-down menu under series. Color swatches for the positive and negative changes allow you to set the colors individually.
Customizing Waterfall Charts
You can change the orientation of the chart from vertical to horizontal. Choose either the vertical or horizontal icon under the General section in the Chart Properties panel.
Many of the other settings applicable to waterfall charts are the same as other types of column or bar charts. This includes labels, axis settings, chart size, plot area fill and legend options.
