Tableau graphs allow you to add multiple mark layers, which has a surprising number of uses. Today, I’m going to demonstrate how to make a chart like the ones above. These charts show a time trend over multiple decades (using the line mark), but also call out the specific decade we’re looking at (using the circle mark). The circle moves when the decade parameter is changed, which gives the user a helpful “You Are Here” marker.

I’ve got a quick upgrade for you today! In this post, I’ll show you how to add a timestamp to your dashboards that shows the last time the data was updated. It’s especially helpful for live data, or manually refreshed extracts, but it’s also just a good habit to include on all pages.

I work with a lot of education data, which means that there are a whole lot of different ways to group students – by demographics, by programs, by history, by focus group, and more.

Making all these filters visible would be confusing and overwhelming, so I use pop-up filter boxes instead. In this post, I’ll take you through how to create easy pop-ups to organize your filters in Tableau.

Adding extra text details to your labels in Tableau makes visuals easier to interpret and clearer. But what happens when the text doesn’t work for every single value in your data? This often comes up when you have both singular and plural values. If the label above said “One speak English”, it would seem a lot less credible! In this post, I’ll show you how to use a calculated field to customize the text in your labels.

I built this dashboard to show key metrics for a Twitter account. (Shared publicly with the account holder’s permission). The dashboard is designed to focus on metrics surrounding tweet topic, time of day, and day of week, to help the user determine the most effective times and topics to increase engagement. 6 different engagement metrics are available (likes, retweets, new followers, profile visits, engagement rate, and comments), and can be toggled using the parameter swap icons.
