Joe Beaven

Joe was introduced to Tableau by The Information Lab at a careers event just before graduating with a BA in Earth Sciences from the University of Cambridge. He then became familiar with geospatial data in his first role after university working at the UK Hydrographic Office, the government office for maritime data. Working in a highly visual space encouraged Joe to become more involved with data visualisation, developing his Tableau skills in his spare time. He is looking forward to applying data analytics in areas of previous experience such as across the Energy and Marine sectors.

Dashboard Week #1: Survey Data

This week is the infamous Dashboard Week for DS16. Every day this week we will be given data at the start of the data. The challenge is to carry out any manipulation required in Alteryx, find a story and build a dashboard in Tableau which has to be published to...

Include a row outside of your Top N when mark is selected on a different sheet

Due to limited space on dashboards, charts with many marks are often cut down to a view which shows the Top 10 or 20 marks. Sometimes we might want to investigate a mark outside of the Top N and see this included on our view. This blog outlines how to build this functionality for both bar charts and sparklines with a use case from Makeover Monday.

Drilldown into data (with formatting and tooltip tricks)

Often on a dashboard in Tableau there is not enough space to display all the levels of detail in your dataset. Set Action drilldowns allow the user to see a lower level of granularity before investigating the underlying data. This blog outlines how to build a bar chart drilldown. I then explain how to build different variations on design including how to show the maximum data point in the underlying data; drilldown arrow headers and vertical titles for the selected header.

Chained Analytical Apps

Chained Analytical Apps are composed of multiple apps that run sequentially allowing a more intuitive user experience. They work by using the output from an initial app as the input for a secondary app and so on. In this blog, I outline a use case for Chained Analytical Apps and how to build them.

Site Roles in Tableau Server

On Tableau Server, there are two main ways to limit content available to certain users – Site Roles and Permissions. Site Roles apply to Users rather than Projects. In this blog, I explain this difference and the different Site Roles available on Tableau Server.

Reflections on Iron Viz

Last week was our first week-long project – creating individual entries for Tableau’s international Iron Viz competition. In this blog, I talk through my final submission. With my project lead coming up next week, I also reflect on the challenges of working to make dashboards over a week.

Tableau File Formats

When saving work from Tableau, just like Excel, there are a lot of file types to choose from. Up until today, I had mainly taken a guess at which option to go for so I was interested to talk through the differences on Tuesday. In this blog, I will try to outline these different file types encountered when working with Tableau to help users choose the right file format for their intended purpose.
