Points and Polygons – together at last. But how? Read on… Tableau has made amazing progress on spatial data over the past year or two. In Tableau 9.2, we got the ability to add new maps through Mapbox, which opened up a world of more detailed and creative backgrounds like satellite or live traffic. Another […]
When I was asked to write a blog about Tableau Server Governance, I pondered how to make it somewhat entertaining. And I don’t think I can. Unless you’re a nerd like me, it’s not an exciting topic. With that in mind, I’m writing this blog as if I were having a friendly chat with a […]
Seemingly every week, there’s a story of an epic failure of a well-intentioned IT project. The company, or government, or charity set out to make changes and incorporate modern technology. They ended up wasting gobs of money and having nothing to show for it. Some stories can be truly mind-boggling, like the US Veterans Administration […]
For years, most of us have been using Excel for data analysis and are now ready to take advantage of the live visual analytics offered by Tableau. Tableau is well worth learning whether it’s for the ability to explore data and get insights quickly, for its automation functionality, for its sharing and collaboration capability, or […]
Recently while working with a client, I came across a challenging scenario: how do you filter the view, using a date filter, without impacting a calculation which included data that didn’t meet the date filter. In this case it was a moving average calculation (i.e., mean of specified time series). This is a tricky situation […]

We turned our attention to business intelligence and building dashboards five years ago and see many parallels. Website designers are always trying to enhance site usage, encourage more engagement, and improve the user […]
Many Tableau users are familiar with measure swapping, an approach to allow increased dashboard flexibility. Users can select metrics as if they were dimensions of the data, when the metrics are in fact columns in a data source. This is achieved with a combination of text parameters in a list, and calculated fields using the […]
Last month, Tableau announced another major release, version 10.4. While there are several exciting new features relating to accessibility, dashboard design and Denodo, I’d like to highlight a big step forward in Tableau’s mapping capabilities. Although Tableau is not a full-fledged Geographic Information Systems (GIS) tool, we use its mapping features constantly at Unilytics in […]
At Unilytics, we’re all about creating visualizations that deliver better insights. But creating meaningful visual dashboards is often really difficult. It’s generally much more challenging than clients think. That’s mostly because it’s not always easy to access corporate data and make sense of it. Disconnected customer and product information is often stored in a multitude […]
Calculating Measures in Prior Years Tableau makes many things significantly easier, but not everything. One very common challenge Tableau designers wade through is computing prior period values. For example, sales data for prior periods that align with the current year to date (YTD). To further illustrate the example, if the current YTD is only 128 […]
