Rank chart in tableau

Tableau is a data visualization tool that helps in a better understanding of data. Rank function is a part of Table functions in Tableau. Rank function as the name suggests is used to give the rank to any measure (number related) present in the data set. The Rank function accepts two arguments, first- aggregated measure (or an expression), second- ranking order (ascending, or descending). Here the second argument is optional, and by default, it assigned as descending. The function will assign the same rank to an identical value.

Illustration:

Let’s take an example to understand the rank chart. Given below are the total number of Covid-19 cases in the following countries.

Data retrieved from https://en.wikipedia.org/wiki/Template:COVID-19_pandemic_data

This data is now converted into a rank chart using tableau.

From this chart we can clearly see which country has the highest number of cases and which has the least number of cases. As we can see here, United States ranks first followed by India and other countries accordingly. The rank chart is used here to give us a better visual illustration of the position of a particular country. With this data, we can determine the countries that is most and least affected by Covid-19 pandemic.

Uses:
