Enhancing your data team with ours
Our consultants come armed with both technical and soft skills to support you to make the most of your data.
The Data School has been paramount to our success at JLL. It has allowed us to bring in highly skilled Tableau and Alteryx consultants. It saves considerable time trying to recruit contractors as I know their skills and training are to the highest standard. Over the past 5 years my team has developed analytical insights which have generated multi million dollar savings of which a considerable amount can be attributed to the Data School consultants we have had working on projects.

Well, lets back track a little

Aggregation and The Learning Process
After a months-long break from academic learning, I can safely say it is nice to be back in an environment where you are pushed to learn and grow.
This week we focused on data cleaning and preparation, something I have done many times in the past but never thought too deeply about

My Mendix Learning Journey
I recently spent two weeks learning Mendix, and I want to share my experience. When I started, I had no real understanding of how the platform worked. Now I have a working application and, more importantly, a much clearer mental model of low-code development

A Busy Calendar? The First Week at the Data School
The first week at a new job is going to have its challenges no matter what. Even more so if it's your first 9-5 job in the big city! There's a lot to get caught up with, and a lot that you're going to be doing.
At least, that was my experience when I started at the Data School

The Datasaurus 🦖: Why Data Visualization Matters

Dynamic Text Label
If you want the text in your label to change dynamically based on a condition, this is a simple way to approach it.
For example, take this chart below that colors the bar if the sales is over 800k.
On top of color, you want to add a text that says "Over" or "Under"

How To Switch Dimensions and Measures with One Click!
To give your user the power to toggle between different dimensions and measures within a single view, you’ll need to leverage Tableau Parameters. Think of a parameter as a dynamic variable, be it a string, integer, or date that replaces a constant value in your calculations or filters

Generating Image Based Scatterplots in Python
While not as pertinent to quantitative analysis, plotting images as scatterplots offers a delightfully creative output for Tableau. Python's computer vision library can be used to analyze an image and generate a csv with generated x, y, and intensity values

Making Makeover Monday Over (On a Thursday)
This week I rebuilt my Tableau Makeover Monday in Power BI. The end goal was the same in both tools: show the largest month to month shocks in gold prices, and let the user control what counts as a shock using a threshold parameter (I used 6%).
In Tableau, the build was straightforward
