Sankey charts

The Sankey chart type contains both columns and a special type of line chart.

Sankey diagrams illustrate a flow through, a process, or a system. Transactional data is optimal for this type of diagram. For example, financial transactions that take place as money moves through accounts or as a product is processed. Many marketing users are familiar with Sankey charts as they analyze sales conversions.

When you build a Sankey chart, you must provide at least 2 (two) attributes and one measure. Your x-axis attributes can contain at most 13 values; any more and you cannot view a SanKey chart.

Many domestic short-haired cats (over 10k) were transferred to other agencies, and nearly as many were adopted. However, all bats that came into the system were euthanized; there is a surprisingly large number of bats processed.
