Using a parameter to filter for specific records in a Tableau dashboard or worksheet

Using a parameter to filter for specific records in a Tableau dashboard or worksheet

Filters are great and all, but I genuinely love Tableau parameters.

One technique that I frequently use for certain dashboard designs is using a parameter as the
primary method of interaction. That is, I use parameters to take input from users, which primarily drives the data viewed on screen. The parameter filters worksheets and shows related information about that input, acting much like a database record selection action or a filter in an Excel spreadsheet column.

For example, say you have a dashboard filled with customer activity for a large retailer. The dashboard might show overall sales per customer, … Read the rest

The importance of exploratory data analysis: Exploring the first B2VB challenge

The importance of exploratory data analysis: Exploring the first B2VB challenge

I kicked off the year participating in a brand-new data visualisation curated by
Eric Balash. It’s called ‘Back to Viz Basics’, also known by its hashtag #B2VB. It’s a fortnightly challenge where the data visualisation community – both new and old – come together to practice some core charting skills. You can read about the initiative here.

The first ‘official’ challenge was on the theme of the scatter plot, a chart type that’s a core communication tool of the data professional. Eric challenged us to analyse some
American college basketball data, specifically on coaching, to … Read the rest

Fun with sets: Highlighting/filtering data using a shared attribute of a selected value in Tableau

Fun with sets: Highlighting/filtering data using a shared attribute of a selected value in Tableau

Have you ever wanted to be able to filter or highlight records in a Tableau visualisation that share a common attribute? For example, say you had a visualisation and a filter that listed animals. You select ‘kangaroo’, and the visualisation would filter for ‘kangaroo’ and all other marsupials – animals that share the same infraclass as the chosen ‘kangaroo’.

Typically, when filtering in Tableau, you filter on a single dimension or measure and the filter action is limited to whatever you selected. Using the example above, if I chose ‘kangaroo’, the visualisation would filter for kangaroos but no other, unless … Read the rest

The Land is a Map: On being awarded Viz of the Day

The Land is a Map: On being awarded Viz of the Day

Last week I was fortunate enough to be awarded my first ever ‘Viz of the Day’ (or VOTD). The more expansive (and I think better version) of the visualisation can be found on my Tableau Public profile.

If you don’t have a clue about what I’m talking about, Tableau – the purveyor of fine data visualisation software – regularly select a visualisation from the community to showcase most weekdays. Typically, VOTD often showcases an interesting new technique or visualisations that provide information on current news or relevant historical events or generates fascinating new insights.

In the case of … Read the rest

An updated Australian international education snapshot dashboard

An updated Australian international education snapshot dashboard

I finally got around to updating my Australian international education snapshot dashboard. The original one, while I think was somewhat novel at the time, suffered from a fair few design flaws. Also, it didn’t render very well on Tableau Public.

Since I originally did that viz, I’ve come quite some way in my Tableau abilities. This dashboard came out of reading some of the thoughts of Robert Janezic, specifically his post “Modern Dashboard Design”, which is well worth a read.

In that post, he links to a great looking dashboard by Ludovic Tavernier. I ended up … Read the rest

Nominated for a 2020 Vizzie Award

Nominated for a 2020 Vizzie Award

I choose a poor week to go on holidays and my time off coincided with the annual Tableau conference which this year was held virtually. I didn’t bring any technology with me during my holiday and thus found it difficult to tune in to what looked like a great series of talks and presentations.

On my way home, I logged into Twitter to see that a local Tableau legend from my home town in Brisbane (Frederic Fery) had tagged me in a picture that showed that I’d unexpectedly been nominated for a Vizzie award in the category of … Read the rest
