Ian has enjoyed playing with data pretty much since he’s been able to count. From reading football scores on Ceefax and scoring his brother’s cricket matches as a child he quickly picked up a habit of recalling scores and spotting patterns.
In recent years, whilst studying Engineering at university, he was drawn into football analytics spheres and discovered other members of the community creating really useful tools in Tableau Public. During this period Ian realised communicating information effectively is an art form and Tableau software recognises this putting data visualisation front and centre.
Ian has come to the Data School to learn from the best, help spread best practices and inspire creativity in data visualisation.
Spray charts are great for visualising change or movement in two dimensions. As an example, the cricket wagon wheel is a classic spray chart. Every shot starts at the batsman's crease and finishes where the ball was fielded. [iframe...read more
We've been at the Data School for 12 weeks now and it's been intense but wholly enjoyable so far. We've been learning two new products from scratch in Tableau and Alteryx, we've been doing client projects since the second week and there's been a stream of after work...read more
In my last post I talked about about spatial data in Alteryx and leveraging Alteryx to do spatial analytics. Now if we want to visualise spatial information in Tableau we need to re-organise our data to make it suitable for importing. Tableau doesn't have spatial...read more
At their core, all spatial data types are a set of points with different properties attached. Points are as you’d guess, sets of one, they are the building blocks of spatial data. They are self contained geolocational points withread more
A technique I use when working out my steps in a workflow is to ‘see’ my tables in front of me and pretend I’m in Minority Report gesturing how I want to pivot, filter, split and join them. This may look a bit silly to colleagues if you over-exaggerate it but each gesture you make will generally correspond to one action in Alteryx.read more
In Alteryx data fields are assigned a field type that is then used consistently for every record in the data field. Field types largely fall into five categories which can then be explored further. Boolean Data Boolean data is the simplest possible form of data. It is...read more
On Tuesday we were tasked with our first Makeover Monday effort at the data school. We went back to Makeover Monday 20 to re-visualise a climate change animation by Ed Hawkins showing the change in global temperatures since 1850. This is the visualisation in question...read more
