Do you want to increase the display font size of a dropdown filter in Tableau? You'd think it would be as easy as increasing the font size in the formatting window, but it isn't. Increasing the font size in the formatting window only increase the title font or the font size of a list, but not the font size of a current selection in the dropdown.
If you want to learn a workaround which allows you to customize the display font size (and also customize what text display when multiple or all values are selected), check out this video!
The visual look and feel of our dashboards make a huge impact to our end-users, and can increase the adoption rate of dashboards, particularly by non-technical users. We can't under-estimate the "wow-factor" of a good-looking dashboard!
But how do you begin to build a good looking dashboard when you're sitting with one that looks like an out-of-the-box Tableau dashboard? The answer is to craft your own design style using best practices and inspiration from others.
Hierarchies are a simple Tableau tool that allows us to drill through dimension levels, from least specific to most specific. Hierarchies typically work best when our dimensional data is organized in levels, like location (State, City, Address), or person (Office, Department, Team, Individual).
However, hierarchies can be limited. The interface to find the drill-down button is not obvious to our end-users, and drilling down from level 1 to level 4 can be cumbersome. In this video, we'll not only look at how to build and use hierarchies, but work through one or two tips on how to create optimized functionality for some selective features of hierarchies, giving you a better overall end-user experience.

Dumbbell charts are an eye-catching way of comparing two values. They can be used for detailed comparisons or simple KPIs. Dumbbell charts are are effective at displaying the relationship between two data points and highlighting the magnitude of change between them. By using a simple yet powerful visual representation, dumbbell charts enable you to easily compare and contrast data points, identify trends, and uncover insights that might be hidden in traditional visualizations.
One of the biggest gripes about Tableau Prep is that it isn't as fast as people want. However, most people aren't leveraging the best way to improve performance; input filters!
Input filters allow you to filter the data at input ensuring that unneeded data is never loaded into and processed in Tableau Prep. This can lead to massive performance benefits.
Ready to learn how to apply input filters and numerous ways they can be configured? Check out this video!
Do you feel stuck when working with bar charts? How do you take them from the standard (although a bit boring) chart we all know to something powerful, engaging, and compelling?
We've put together a free webinar on our 12 top tips to taking your bar charts to the next level.
We looked at things like:
•Color-changing labels
•Multi-axis bar charts
•Multiple labels on a bar
•Drilldowns
Do you want a warning message to pop up in Tableau when there is no data or a user makes an invalid selection? Look no further, we've got the solution for you!
We've worked with numerous clients to help them apply their own version of this method to their dashboards. Ultimately, it comes down to creating a warning message sheet, putting it in a vertical layout container with the worksheet it will replace when activated, and applying some logic and customizations to the warning sheet so it only shows up when you want it to.

If you're looking to turn your static Tableau dashboards into interactive powerhouses, buttons are a fantastic way to do that! In today's tutorial, we're diving into one of Tableau's most underutilised secrets: using buttons to control parameters. This isn't just about making dashboards look sleek (though they absolutely will), it's about creating an experience so intuitive that your users will actually want to explore your data.
