Group waterfall by SWHK

A grouped waterfall chart displays the step-by-step changes in positive and negative values for different categories over various periods. It is commonly used in income statements, cash flow analysis, and budget versus actual reports to show the impact of individual elements on the total amount. Supports standard waterfall charts, can also add grouped waterfall charts with two layers of data, and supports grouped waterfall charts with three levels of classification, such as comparing the development trends of the same indicators across different years. Each bar in the chart is labeled with an individual change, color-coded to show positive or negative offsets. This layout provides a clear, step-by-step view of the data change process. Subtotals can be emphasized to highlight intermediate steps and clarify the change process. Waterfall charts present detailed data in a more readable structure, showing not only the final result but also how it was achieved. They are ideal for tracking performance changes, mapping financial dynamics, or sharing updates in a structured visual format.
