Can you do a Sankey diagram in tableau?
Tableau Sankey chart diagram is a visualization used to depict a flow from one set of values to another. Sankeys is best used when you want to show a many-to-many mapping between two categorical dimensions. Sankey chart in tableau is a good alternative to bar charts or pie charts if you wish to show flow quantities.
How Sankey diagram is useful for energy analysis?
Sankey diagrams , which are typically used to visualize energy transfers between processes, are named after the Irishman Matthew H. P. R. Sankey, who used this type of diagram in a publication on energy efficiency of a steam engine in 1898. Sankey diagrams are ideal for visually representing energy balances.
How do you find the efficiency of a Sankey diagram?
Divide the useful energy by the total energy and you will get the efficiency which should be between 0 and 1. Multiply by 100 to find the percentage efficiency.
How do you create a Sankey diagram in Google Sheets?
Sankey Diagrams within Google Spreadsheets
- Open a spreadsheet.
- Click “Tools” -> “Scripts”
- create the two files code.gs and index.html.
- insert the document ID from the URL on line 10, code.gs.

What is a Sankey chart used for?
A sankey diagram is a visualization used to depict a flow from one set of values to another. The things being connected are called nodes and the connections are called links.
Where on a Sankey diagram is the wasted energy?
We can use a Sankey diagram to show how the energy is transferred in a system. This gives us a picture of what is happening and shows the input energy and how the output energy is made up of useful energy (arrow at the top) and wasted energy (arrow going to the bottom).
Can you make a Sankey diagram in Excel?
Sankey diagrams are used to show flow between two or more categories, where the width of each individual element is proportional to the flow rate. These chart types are available in Power BI, but are not natively available in Excel.
What is Sankey chart in tableau?
Sankey chart in the tableau is a great diagram. This diagram will show the flow and relationship between two different elements. These two different elements are called nodes and relationship or connection between two different elements called as links.
What is a Sankey diagram?
Sankey Diagram is a chart that we can use to visualize the flow of one measure over multiple dimensions. Sankey Diagram was invented by Irish Captain Sankey to describe the energy flow in a steam engine. There are several use cases that suitable to be visualized with a Sankey Diagram.
What are nodes and links in a Sankey chart?
These two different elements are called nodes and relationship or connection between two different elements called as links. When we have two different dimensions (it is qualitative data or description of data) and want to know the relationship between them or mapping then the Sankey chart is the best way to use.
How to make a Sankey diagram in Excel 2016?
Do it by dragging the Chosen Measure to Rows and change table calculation to Percent of Totals. Then add Dimension for color and text. Also, add INDEX () for color in Marks for the right side of Sankey. As a final step, we need to arrange all the sheets and filter together to get our Sankey Diagram.
