    e!Sankey is used by more than 8000 users in over 85 countries to visualize material and enery flows and to create appealing Sankey diagrams. Test e!Sankey free-of-charge with the 14-day trial version.

    e!Sankey - show the flow.

    The software e!Sankey lets you create Sankey diagrams quickly and easily. No matter whether you wish to depict energy flows, material streams, or goods being transported along a supply chain: use e!Sankey to create convincing visualizations for your presentations, reports and publications.

    Sankey diagrams are a great way to visualize flows – e.g. energy, material, or cost flows. The width of each arrow in a Sankey diagram is proportional to the flow quantity, i.e. a flow with double the volume as another flow is shown with an arrow twice as wide.

    Sankey diagrams immediately draw the attention to the most important flows. They are gaining increasing importance in energy management, facility management, process engineering and in the area of resource efficient manufacturing.

    When visualizing costs along a supply chain or within a production plant, they can help to better understand value streams.

    e!Sankey is a dedicated software tool for such Sankey diagrams. With its set of features and numerous layout options it provides all you need to show the flow.

      What are Sankey diagrams?

      Sankey diagrams are a specific type of flow diagram. They are used to visualize material streams or energy flows.

      They are used, for example, in energy management, facility management, chemical or process engineering. Sankey diagrams are a good alternative to bar charts or pie charts, if you wish to show flow quantities.

      In Sankey diagrams the width of the arrows are proportional to the flow quantity it represents. So, attention is drawn immediately to the most important flows in the process system.

      Who is Mr. Sankey?

      Sankey diagrams are named after Captain Matthew Henry Phineas Riall Sankey, an Irish engineer, who was working on energy efficiency of steam engines. He published the first energy flow diagram of this kind in 1898.
