When should you use Table Calculations and when should you use an LOD? There are differing opinions out there...
When the calculation is dependent on information in your window, use a Table Calc. When it's independent, use an LOD.
Unless... your workbook starts to show performance issues.
Tableau's parameters are variables that can take the place of constants. They are the primary tool that we use when we want to add interactivity into our views, allowing our end users to interact with sliders, drop-down menus, and type in boxes to change the values in the views.
Parameters can be used to change values in a filter, a calculation or even a reference line! In this video, we'll look at the most important things you need to know to work well with parameters.
Do you want to add multiple totals to the bottom of a worksheet in Tableau? Maybe it would be useful for your user to see both a sum and average of the values in your sheet, but Tableau won't comply.
Unfortunately, Tableau doesn't offer the ability to add multiple totals to a table out of the box, but with a little creativity, we can get there! Some key ingredients include, Level of Detail Expressions, a unique worksheet for each total and some dashboard formatting.

Tableau Prep is a powerful tool which allows users to clean and model data at will. It's infinitely customizable and allows for users to apply whatever transformations and alterations they deem necessary to build the data source they need for their analysis.
Tableau Prep provides a compelling alternative to writing thousands of lines of code or paying an arm-and-a-leg for a legacy software solution. There has never been a better time to add Tableau Prep to your toolkit of solutions!
In 2024, the United States Department of Justice ruled that all state and local agencies need to have WCAG-compliant websites by April 2026. That also applies any embedded content (like Tableau dashboards!).
If your organization is subject to this ruling, there is limited time to get ahead of things!
In this week's webinar, we shared some practical suggestions we've developed while working with clients to ensure their Tableau content is WCAG-compliant ahead of the April deadline.
Regular Expressions are a family of functions which allow you to identify patterns in text strings and perform a manipulation based on a pattern that is recognized.
REGEXP_MATCH can determine if a substring is present in a larger string and REGEXP_REPLACE can replace a list of values with a predetermined output. These are more powerful than standard functions like CONTAINS and REPLACE because they can handle multiple search criteria at once and the can match on patterns (e.g. ABC-123) rather than exact text matches.
