Placing Multiple Labels in Trellis Chart
Sharon left a message in my last post on Labeling Trellis Chart Anywhere asking whether we can have one label on the left and another on the right per trellis chart cell in Tableau. Yes we can. Below we will show how to place multiple labels within a trellis cell.
Creating Compact View of a Sparse Table in Tableau
Catherine came to my office asking if we can create a compact version from a sparse table in Tableau, so that the table would look a lot more compact. This allows a succinct view of the table content. It saves screen real estate and makes it easy to read for business audience.

Pre-Filters, Post-Filters and the Order of Operations in SQL
In data analysis, we need to use filters here and there. In general, we would classify them as pre-filters or post-filters for better understanding of their respective mechanisms.
A pre-filter works on the data set. It only keeps the data we need for the analysis.A post-filter works on the results.
