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.

Preparing Spatial Data for Tableau

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...

Spatial Data in Alteryx

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 with

Seeing Tables and Building Workflows

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.

Field Data Types in Alteryx

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...
