Diego Parker

After completing a degree in International Relations in 2017, Diego worked in a consulting company focused on attracting foreign investments for the development of sustainable projects in Chile. There he discovered the importance of data-driven decisions and decided to start learning data analysis tools during its free time. After six Excel online courses he finally discovered Tableau, but he did not know where to start. It was during this period when he decided to move from Chile to the UK and by some ‘divine intervention’ he stumbled across The Information Lab online.

Before moving to the UK, Diego was always using every opportunity he had to travel. He volunteered in China and Greece as an English teacher and did one year in the UK as an exchange student before deciding to move indefinitely.

Outside the classroom, he likes to interact with the community in Twitter, play boardgames and read. The book that inspired him to start his data career was Factfullness by the Gapminder Foundation.

Dashboard Week #5 United States Interstate Traffic
Today was our last day of #Dashboardweek, what a week has been! The data was about United States Interstate Traffic. Because Friday is presentation day at the DS, we only had until one to prepare the data and create a visualisation

Dashboard Week #4 United States Drought Monitor
Today was our fourth day of #Dashboardweek and we had to look into drought levels in the United States. For the first time in the week I ran out of time, which means I’m breaking the rules and posting this nearly one hour after the deadline

Dynamic axis and sorting with parameters PART 2
If you have read part one, then you already know how to build a dynamic axis, and, in this post,  I will explain you how to create a parameter to let your user sort between ascending descending

Dynamic axis and sorting with parameters PART 1
Parameters are one of the most useful tools that Tableau has. They allow the user to input their own values, which allow us to create self-served dashboards and dynamic dashboards that won’t require a constant update

Diego's journal (DS12) - Week Six
Week Six (14/01/19 – 18/01/19) As we are currently in week 11, I must confess I have fallen behind on my journaling. However, before the memories fade completely I’ve decided to write a small recap of the things that we did and learnt during week six

Tutorials from the forum #1: Sheet swap using images
As I have recently started my journey in the Tableau community forums, I have come across different questions. One of them has repeated a few times and I thought I would make a blogpost using the tutorials I’ve already wrote on the forums, so more people can find them

How to build a linear trendline for calculations
One of the analytical features that Tableau offers is the capability to build a trendline with just a couple of clicks. However, trendlines in Tableau do have some limitations, among them is that you can’t use them within your calculations

Dynamically Controlled Bins
What are bins? In short words, bins are the groups in which our data is “contained”, such as categories, dates or range of numbers

Diego's journal (DS12) - Week Two
Week Two (10/12/18 – 14/12/18) Week two was about data visualisation and we finally got to use Tableau. However, it wasn’t until Wednesday when we finally used the software, as the previous days were more about the theory behind good data visualisation

Diego's journal (DS12) - Week One
Week One (3/12/18 – 07/12/18) Week one started and as a way to remember my experience at The Data School and the content I have been learning, I decided to keep a weekly journal to which I can come back. After a long application process and a month of waiting, the Data School finally started

Joins and Unions
My first application to the Data School was made of four different databases. If you are working with multiple databases you will have to tell Tableau how these databases will interact with each other, inevitably, these made me stumble upon joins and unions too soon for my own good
