Features to create appealing Sankey diagrams

Using e!Sankey you can create easily and quickly appealing Sankey diagrams.

Read here about functions & features the software provides to make the set-up of your charts even more comfortable, e.g. by linking values in a Microsoft Excel worksheet to flows in the diagram using the Live Link.

All features for creating Sankey diagrams

e!Sankey is specialized to draw one specific type of diagram: Sankey diagrams.

It provides all features and many different design options to visualize energy flows and material streams as appealing flow diagrams.

Drawing Sankey diagrams is easy as pie

Building up Sankey diagrams is intuitive and only requires knowledge of a few basic functions of the software:

  • Set a process (node)
  • Draw an arrow between the processes
  • Drag&drop material or energy flow entries into arrow
  • Add quantity of material or energy

The correct width of the Sankey arrows is calculated and drawn automatically based on the flow quantities entered. Proportionality and scaling of flows is ensured, even when elements of the diagram are moved.

Free drawing of arrows and nodes ensures a highly customized design.

Test it now: download e!Sankey trial version

You can create the first professional Sankey diagrams within a few minutes. Try it out yourself with the free 14-day trial version of e!Sankey. It contains a large number of sample diagrams and also comes with a full user manual that will help you understand all functions of the software.

Many different options for arrows

Once the Sankey diagram with its arrows whose width is proportional to the flow quantity has been set up, it can be adapted and refined. Many different layout options are available in e!Sankey to make the diagram look good:

  • Adapt arrow routing: instead of drawing the arrow directly between two nodes insert waypoints to determine the arrow routing. Also, you might want to define that arrows must dock at a specific side of the process symbol
  • Design arrow heads: can be turned on or off, shape and size of the arrow spikes can be set
  • Icons or images: personalize your diagram using process symbols

Overview of all e!Sankey Features

Export of diagrams as image file

After creating your diagram, you can export it as an image file, to show it in a report or to include it in a PowerPoint presentation. Scaling and image resolution can be defined in a dialog. The following graphical file formats are available:

  • BMP, GIF, JPG & PNG
  • PDF
  • EMF

When using the diagram exported in Microsoft Office applications we recommend e.g. the EMF format.

Updating Sankey diagrams with data from Microsoft Excel (from e!Sankey pro)

When doing monthly reports, or regularly publishing flow data, it is often sufficient to just update the values in the Sankey diagram.

To this end the Live Link to Microsoft Excel can be used: flows in the diagram reference into cells in a workbook. When these values in Microsoft Excel change, the flow quantities are adapted and the arrows get updated accordingly.

By the way: this mechanism of updating Sankey diagrams with data from external sources can also be automated using e!Sankey SDK. This opens new possibilities to integrate Sankey diagrams in other software solutions, such as e.g. energy management software.

Visualization of stock changes (from e!Sankey pro)

Especially in material flow management visualization of storages & stocks is an important requirement. 

To ensure the flow character of Sankey diagrams, you can enter stock values before input & after output. These stocks will be displayed with proportional bars.

Thus you can see stock changes at a glance.

 

 

Calculation of entries and flows through process operations (from e!Sankey calc)

Using the following operations you can specify your processes in order to calculate entries and flows in your Sankey diagram, e.g. if certain data is missing:

1. Sum:
Calcuates the sum of all input flows and creates a flow at output arrow.

2. Merge:
Takes all flows from all incoming arrows and passes them to the output arrow. Flows of the same entry will be summed up.

3. Difference:
Calculates the difference of the surrounding flows and creates a flow at the output arrow.

4. Split:
Takes all flows from all input arrows and passes them to the output arros. Flows are split by given ratio.

Customer Testimonial

Customer Testimonial

"Statistics can be boring, technical and taken out of context. Diagrams from e!Sankey connect the dots, show with colours the different orders of magnitude and as a whole make the data more fun and understandable to everyone. Diagrams from e!Sankey are very quick to make and are especially well suited in order to display energy systems, both at the industrial, local and national level."
Julien Morel, Energy Analyst, Swedish Energy Agency

Back in 2000 we already implemented the visualization of material and energy flows as an integral feature in our material flow analysis software Umberto. We thought it would be cool to also provide this Sankey diagram drawing features in an own, dedicated software. So, in 2007 we launched e!Sankey. And since it apparently hit a demand in the market, we have continued to develop it as a product of its own, and will do so in the future.
