Sankey Bar Charts - User Guide


Sankey diagrams provide a visual depiction of the magnitude of flow between nodes in a network. Bar charts display data for a discrete variable (e.g., category, event, timepoint). Combining Sankey diagrams with bar charts allows users to track the path of data throughout multiple steps or stages of a system. The Sankey charts provided on this site include static SAS versions and an interactive web-based version.


Basic instructions for creating a SAS Sankey Bar Chart are embedded in the Examples, Getting Started and More Options. Additional information about the SAS macro is available in the PharmaSUG paper.
