Harry Cooney

Harry first came across data analysis in his Psychology degree. He quickly realised that this was actually the part of the course he was enjoying most. A weeks work experience in data analytics confirmed it was the industry that would be most enjoyable and fulfilling to him. To develop his skills in data analysis he completed an online data science course and discovered Tableau. The speed and creativity it allowed further cemented his desire to work with data. He immediately started collecting and visualizing data on topics that interest him, and listening to podcasts related to data analytics. It was through one of these podcasts that he heard about the Data School and knew it was ideal. He is looking forward to learning how to use Tableau and Alteryx to solve business problems.

Outside of data Harry enjoys travel, football (watching and playing) and socialising.

Tableau Dateparts vs Datevalues
Dates in Tableau will behave differently depending on whether they are a datepart (blue) or a datevalue (green). This affects how the axes display/behave and also how visualisations such as line charts will display

Dashboard Formatting With Containers in Tableau
Before joining the Data School dashboard formatting was a nightmare. I thought that the sizing and position of things relied on the eye alone and would spent ages resizing things and trying to make them align in an aesthetically pleasing way
