When using Tableau, you might occasionally create a worksheet that uses dimensions only. Imagine you created a worksheet displaying an organizational hierarchy that looks like this:
When embarking on a data communication project, you might not always have all the data you need to create a prototype in a timely manner. I often generate realistic, placeholder data sources so I can design a dashboard and get feedback, even if the actual data isn’t ready for display yet.
If you're familiar with Level of Detail expressions in Tableau, you probably know that the FIXED function gets all the love. However, there are some great reasons to consider using the other two as well. Check out the above video to learn when to use the EXCLUDE function.
Here's an interesting challenges; how do you compare this year's values to the average of the previous 3 years in Tableau? The complex solution requires the use of the FIXED level of detail function. Watch the above video to follow along and learn how to perform this calculation.
Imagine you have a busy worksheet in Tableau that looks like this:
Each line represents a single facility and displays that facility’s overtime hours. Imagine you want to filter to only keep the trends for the 3 facilities with the highest overtime hours from the most recent date BUT you also want that filter to be dynamic so when you update the data there might be a new top 3.
If you have a data set that updates irregularly, figuring out how to filter to show only the latest data is difficult. Relative Date Filters are great but only work well if you have a set time you are filtering to like “today” or “yesterday”. If your latest data could be today, yesterday, or two days ago depending on the refresh schedule, things get trickier.
Yes, you can! Check out the image below for an example.
If you've ever tried to compare part of your data to the whole in Tableau (and give your users flexibility to change the view), you might think it's not possible. Check out the video blog above to learn about an innovative solution a client and I developed to solve this problem.
Remember the Attribute function? It returns a value if there is only a single value for a result set, otherwise it returns an asterisk.
As you likely know from using Table Calculations in Tableau, they only compute against the marks displayed in a worksheet. Check out this webinar in you need a refresher.
That means when a filter is applied to the worksheet, a table calculation will update to reflect only the data present in the worksheet.
