Having spent 5 years studying at the University in Kent in Canterbury for his BSc Mathematics and MSc Computer Science degrees Jonathan began putting his analytical skills to work in the IT support sector. However, he soon found he missed being able to use mathematics and lacked a creative outlet.
After researching how to get into data science, Jonathan stumbled across Tableau and the Data School and hasn’t looked back since.
Week 6 of the cohort 13 at the Data School was the least lesson-focused week so far, with the focus instead around the project with bursts of teachings sprinkled in. Day 1 Unlike the previous week, this week we were working with clients within our timezone and thus...
Suppose we have a car dealership dataset that has a row for each week of the year and a column for each colour of car indicating how many cars of that colour were sold that week. DATE | Red Cars | Silver Cars | Black Cars | Blue Cars What if we then wanted to create...
This week was a bit of a milestone week for a number of reasons including the fact that it was our first client project and also the week where we all signed up to take the Tableau Desktop Qualified Associate exam! I think one of the trickiest things we encountered...
Day 1 This week kicked off with two days of learning about Alteryx Macros with Phil Lowe. In short, Macros are a workflow packaged into a single tool. The purpose of this can be to provide interactivity to a workflow, make a complex process simple to use, or allow a...
The ability to drop floating containers inside other floating containers is in my mind the single more important tip when it comes to designing and building dashboards.
For those of you obsessed with key-stroke optimisation here’s a neat little trick for saving a few key strokes every time you want to type out a number with large display units, e.g. thousands, millions, billions.
Learning to use containers can be tricky and you may even wonder why bother using them at all. Well, this is part 1 of a short series to demonstrate how & why you should get to grips with containers!
Week 3 covered a real spread of Tableau products including Desktop, Prep, and our first real glimpse into Tableau Server! It was also filled with other exciting (scary) news such as finding out the date for our first teaching-the-public event, as well as finding out...
Most vizzes use either dollars or pounds, but what do you do if you need another currency symbol or format? No, step away from Google, Tableau has the answer built-in!
Week 2 was focused on what brought us all to the Data School in the first place – Tableau Desktop. Almost an entire week dedicated to data visualization best practices, design methodology, and practical Tableau learning
It can be useful to give different measures their own colour schemes but it isn’t immediately obvious how to do this. Here’s a quick guide that shows you how!
Want to quickly visualize some unsaved data? You can paste it right onto a blank Tableau worksheet! You can then even save it as an extract for future use. Mindblowing.
Rounded. Bar charts. Just look at those curves. As a newcomer to Tableau the discovery of rounded bars is ground-breaking. Making your first rounded bar chart feels like you’ve transcended from using your Grandad’s clunky square bars to the world of sleek, futuristic...
I’ve now been at the Data School for a full week and I can honestly say this has been one of the best weeks of my life.
If you want to display a bunch of data points that are contained in a single region, you may not want other regions cluttering up your map. Here’s a quick hack on how to fix this!
The default “zero line” is weak. Create a stronger zero line using a “Constant Line” to give your bars a better foundation!
