How to Create a Dendrogram in Tableau - My Way

A dendrogram, also known as a phylogenetic tree, shows the evolutionary interrelations of a group of organisms derived from a common ancestral form. The ancestor is in the tree “trunk”; organisms that have arisen from it are placed at the ends of tree “branches.” The distance of one group from the other groups indicates the degree of relationship; i.e., closely related groups are located on branches close to one another. Phylogenetic trees, although speculative, provide a convenient method for studying phylogenetic relationships. A dendrogram can be generated by coding using libraries like scipy , Matlab , and plotly . However, how do you create one on Tableau? Using an image of a dendrogram from Matlab, I will demonstrate how. Step 1: Draw the Dendrogram Using Any Software or Pen and Paper (image from Matlab) Step 2: Mark the Lines for Each to Look Like a Full Bar Chart Step 3: Label the Rows with Numbers Step 4: Label Columns with Numbers Step 5: Enter the Numbers in...

How to Create a 9-Box Employee Rating on Tableau - My Way

What is a 9-Box Employee Rating? The 9-box grid is a well-known talent management tool in which employees are divided into nine groups, based on their performance (represented by the horizontal axis) and potential (represented by the vertical axis). Can I create a 9-Box Employee Rating on Tableau? Yes, you can. This has already been done by Decisive Data. Check out their version here . So why do we need this tutorial? There are still posts on the Tableau forum asking how it can be replicated and there are no proper tutorials to answer. First, ask by Beth in 2014 . Then again by Arihant Jain in 2020 . Finally, another time by Ittikorn Sriratanarungrueng in 2020 . Unfortunately, the answers were either lacking or short. Hence, I have decided to give this a shot partly inspired by Nasheed Sabree's replies on the first and second forum posts that write, " This is definitely possible in Tableau. Simply assign a number to each combination (9 combinations) and use this field as a f...
