Week numbers with Tableau
The previous post discussed different methods of calculating week numbers and their effects on analysis and visualizations of data on a weekly basis. The post was focused on using Microsoft Excel.
However, the challenge caused by different week numbering methods is not restricted to Microsoft Excel. I guess every data analysis and visualization software faces this problem.
And so does my favorite: Tableau. There is no built-in way to switch between different week numbering methods in Tableau. But Tableau has the flexibility for an easy-to-use solution. This post provides all information of how to use ISO 8601 week numbers in Tableau, including a Tableau packaged workbook for free download.
For analyzing and visualizing data on a timeline we are often consolidating the data on a monthly basis. Especially for monitoring and reporting, however, you need a higher level of detail, i.e. you will have to analyze and visualize your data by weeks.
