Recreating a Monetary Sankey in Tableau
Yesterday somebody posted a query on the Tableau Group web page here relating to my method to constructing sankey diagrams in Tableau. The individual was asking if it was doable to create the next sankey diagram in Tableau.
I posted a prolonged response on how I might method this drawback, however I made a decision to recreate this instance in Tableau to point out {that a} conventional sankey is most definitely doable. Utilizing essentially the most rigorous of scientific strategies to assemble the information (a ruler on my display estimating the width of the bars), I recreated the information for this visualization. I used the tactic outlined in my earlier posts with some slight changes for the gaps which I focus on on the Tableau Group publish.
In my first method I « Tiled » the sheets which makes it very simple to line up. Nonetheless, I do not notably like this method as a result of there’s a giant hole in between the tiles. This creates a Scintillation Impact similar to a Hermann Grid that I would favor to keep away from (Extra data on the Hermann Grid and the Scintillation Impact here).
Through the use of floating tiles and shutting the hole that is simple to unravel and appears extra like the unique visualization.
As earlier than, the toughest half is creating and shaping the information. The excel file I used for this visualization is out there here. The tabs stroll by my method to the information within the numerous steps earlier than importing into Tableau. As soon as the information was able to form I merely used the Excel Macro that I posted final month here. This created the formed information that was instantly able to import into Tableau.
I hope you discover this extra instance useful. As all the time, when you’ve got any questions be happy to electronic mail me at Jeff@DataPlusScience.com
