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?
Need to hire a Tableau Developer? We can help!
Hiring someone is a daunting task! How do you find the right person? How do you know if they'll be a good fit? How do you assess their experience level?
We've partnered with Tableau since 2014 to facilitate training sessions and consult on Tableau projects. During that time we've trained thousands of users and helped hundreds of organizations maximize their use of Tableau.
We're often asked to help those organizations with the hiring process. In this video, we've distilled some of our biggest takeaways that can help you find the right candidate for your team!
Can you make a Tableau Public dashboard private? Kind of!
In this video, we’ll look at a great alternative to hosting a dashboard on Tableau Cloud! You don’t need to purchase multiple licenses for the viewers of your dashboard. All they need is the URL!
While not as secure as a Tableau Cloud solution, hosting a private dashboard on Tableau Public can be a viable alternative if your data isn’t extremely sensitive, or you have a large viewer-base.
Do you need to publish public Tableau reports but suppress small populations because of sensitivity concerns?
If you work in healthcare, education or another government entity, there's a good chance your Tableau reports contain sensitive information that needs to be suppressed. For example, many organizations we work with need to suppress populations when they are less than five. For example, if we filtered a courts dashboards to see how many court cases there were in Whatcom county for 12-14 year old, Pacific Islander females in 2017 and there were three cases, we would need to suppress that figure because it's less than five.

Text tables can be overwhelming for users. It's hard to know where to focus your attention!
Where are the highest and lowest values in the data? What patterns are there? Upgrading a text table to a highlight table can often do wonders, but a highlight table doesn't provide a singular focus. It will likely highlight high, and maybe low values too.
That's where a custom highlighter can be so handy. Why not let you user control which values they want to call attention to?
Do you have an object in your Tableau dashboard that should be expanding and contracting but isn't?
There are a number of reasons you might set up an object to expand and contract. Maybe it's a detailed sheet that should only display when the user makes a selection from the summary sheet at the top of the dashboard. Maybe it's a parameterized worksheet swap. Maybe you've set up a simple show/hide button for your user.
Regardless, when an object is in a layout container and isn't expanding and contracting as desired, it's frustrating!
Normally, when using a parameter to swap between measures, you're limited to using a single number format in a text table. But what happens when using the same number format makes no sense?
In our example, we're swapping between Total Cost (reported in $) and Visits (a count). We don't want to report Visits as a dollar-denominated amount, and we don't want Total Cost to be reported without a dollar symbol! So what can we do?
Adding comments to fields in Tableau is important to document your work and keep things organized!
For example, you might have two fields with similar names! Adding a comment to them can help you quickly distinguished them in the data pane.
Need to get some Tableau training for yourself or your team? We've got you covered! Whether you want to dive deeper on Tableau Desktop, Tableau Prep, Calculations or Dashboarding, we've got a class for you!
In Winter 2024, we're teaching 12 public classes across Pacific, Eastern and Central European Time.
Have you ever been asked to include a table of data that’s way too detailed for the dashboard you’re working on? Sometimes we really just want to see all the numbers. But we might not necessarily want to display all that information at once.
That’s where a Show/Hide option could be effective. Using a parameter, we can enable our end-users to select whether they want to see all the data in the underlying table, or just some summary data (like some total columns).
One of the biggest problems with scatter plots is that all the data points on the chart can be overwhelming without context.
Scatter plots are one of the most powerful visuals you can build in Tableau. They allow you to plot numerous data points to identify correlation and patterns in your data set. However, they can also be overwhelming for an end user.
Using resources like average lines and colors to identify data points with "desirable" versus "undesirable" outcomes can expedite your users' ability to properly comprehend the data.
Do you need immediate Tableau help?
When you're up against a deadline, you don't want to sit around hoping that someone responds to you in a Tableau forum or that Tableau support gets back to you in time. You definitely don't want to get caught up in a lengthy contracting process with a large consulting firm.
At OneNumber, we make the process of getting expert Tableau help as streamlined as possible. You can generally book an hour with Tableau accredited trainers and consultants Eric or Ollie in the next two days!
Tableau WINDOW functions allow you to apply an aggregation to aggregated data points in a worksheet.
This is helpful when you want to calculate the average, minimum or maximum of your data points! These functions can help you draw average lines, differentiate between values that are above or below average, or even highlight the largest and smallest values in your visuals!
WINDOW functions are a core component of maximizing Tableau's ability to communicate valuable insights about your data.

How do you track trends in Tableau when there is a high degree of fluctuation in our data? Try using a moving average!
A moving average is an average of a collection of points around a specified point. For each mark in our view, Tableau will calculate the average of the mark's value and the value of several previous marks. This creates an average value that "moves" over time.
