The Sankey chart type provides a powerful way to visualize the movement and transformation of data by combining elements of columns with a specialized flow-based line chart.

Sankey diagrams are designed to illustrate a flow through a process or a system, making them an excellent choice for transactional data. They are particularly effective for showing how money moves through various locations, while tracking the payment methods used.

When building a Sankey chart in the chart builder, you must provide at least two attributes and one measure. To ensure the chart remains readable and effective, your x-axis attributes can contain a maximum of 13 values; exceeding this limit will prevent the Sankey chart from rendering.

Trends AI reads Sankey charts from left to right. The width of each flow line directly represents the volume of the measure, while the attributes or specific "steps" in the process appear as solid vertical bars.

For instance, using data from this dashboard in Subsplash Giving, you can track the types of payment methods used by different organization locations. In this case, the measure is the total amount of gifts in dollars. The resulting chart provides a clear overview of the amount and payment methods used by each campus of this organization.

By selecting a specific flow within the chart, you can view the exact total for that path. For example, you might see that the Australian location received a total of $305.73 paid by card.

Please note that Sankey charts do NOT support conditional formatting.
