Do you want to label just the first and last point in a graph in Tableau? For a line graph, that's simply a couple clicks away. But for a bar chart or any other type of graph, it might be a bit more involved.

Our go-to method for labeling just the first and last points is to write a table calculation utilizing the FIRST() and LAST() functions and to drop that on the label tab in the Marks card.

A fundamental component of Tableau Prep is the ability to clean messy data. One of the best ways to do that is by creating groups! However, creating groups can be confusing. How does Tableau Prep decide what to name a group? For example, if you group "Boise" and "Boise City" together into a single city name, which does Tableau Prep choose? Well, that all depends on the grouping method you select.

Automated Groups: If you use automated groups (grouping on pronunciation, common characters, etc.) it will choose the more populous value. So if there are 100 rows for "Boise" and 5 rows for "Boise City", the group name will default to "Boise".

FIXED Level of Detail Functions (LODs) let you specify the level of detail you want to aggregate a particular measure at. This allows us to work around the natural limitations of the level of detail in the worksheet we're working in.

FIXED LODs are a great place to start as they are the definitive, essential LOD. The two others (EXCLUDE and INCLUDE) are less common, but functional in their own unique ways. If you want to simplify and just learn one LOD type, FIXED is the one for you!

Do you want to build a customizable, dynamic date range filter in Tableau?

For example, imagine you want the filter to default to the last 14 days ending with today's date, but you'd like your user to be able to adjust the end date and number of days in that filter.

That combination of functionality is not available out-of-the-box in Tableau, but with some creativity, parameters and calculations, it's possible!

How do you add a Quarter and Year list filter in Tableau? By default, Tableau lets us add a Quarter Number filter (e.g. Q1), but getting a Quarter and Year filter list isn't a standard option! As a result, we need to workaround this a bit with three possible options.

Which one works best for you depends on your use-case, but all three will be helpful to know in your Tableau work.

One of the primary purposes of a dashboard title is to provide context for users. It should give them a sense of what they are looking at, and what they are looking for.

My favorite way to add value to a dashboard title is to have it reflect filter selections. For example instead of saying "How is our hospital system performing?" it could say "How is Trinity Northern performing?" when the dashboard is filtered to a single hospital.

Do you want to incorporate password protection for your Tableau Public Dashboards?

Using a parameter and a random string generator, you can get pretty close! While not totally comprehensive, it's a great element to incorporate into your dashboards if you want to keep them somewhat secure without investing in the Tableau Cloud services for a wide viewer base.

Filtering on a date range in Tableau is pretty straightforward, right? But how about if you want to filter on that date range AND you want a comparison date range filtered at the same time? That's trickier.

For example, you set a filter from January 1st to March 15th 2024 and you want a comparison period of January 1st to March 15th 2023 to automatically be set, how do you do that?
