#MakeoverMonday Week 37 - First time home buyers in the UK are being shut out of the market

No comments
Have you ever heard of the "sunken cost fallacy"? If you haven't, it is where you continue a task based on previously invested resources, such as time, despite new evidence suggesting that the cost, beginning immediately, outweighs the expected benefit.

This is what nearly happened to me during Watch Me Viz. I was convinced I had created the perfect chart. That is, until comments started coming in to the contrary. I had gotten so fixated on this one chart that I thought all other ideas were inferior.

I snapped out of it eventually and turned my attention to another chart that told the story much better.

The lesson learned: be careful of, and attuned to, sunken cost.

With that, here's Watch Me Viz for you to follow along and learn lots about Tableau.

Mastering Tableau: The Power of Context Filters

No comments

What are Context Filters?

A context filter in Tableau is a powerful feature that allows you to isolate a specific subset of data and create a temporary data subset 

When you apply a context filter to your visualization, Tableau first applies the context filter and then performs calculations and aggregations based on the filtered subset of data.

How do they work?

By creating a context, you can optimize the performance of your visualizations by reducing the amount of data being processed.

When a context filter is applied, Tableau performs the following steps:

  1. Identifies the data that meets the context filter criteria.
  2. Performs calculations and aggregations based on the filtered data.
  3. Evaluates any other filters and calculations based on the context data subset.

A context filter allows you to control the order in which Tableau applies filters and calculations.


In this video, I'll explain:

  1. The difference between regular filters and context filters
  2. How context filters can significantly improve Tableau performance

I'll finish up by showing you a couple of the most common use cases for Context filters to drive the concept home.

Create 10 ACTIONABLE & IMPACTFUL KPIs in Tableau

No comments

What is a KPI?

KPIs are measurable values that indicate how well a business is performing in achieving its key objectives and goals. They provide a clear and concise snapshot of critical areas within a business.

KPIs help to:

  • Monitor progress

  • Identify areas of improvement

  • Make data-driven decisions

In order to do this, KPIs must be tailored to specific goals and strategies.

Making KPIs Actionable

Here are 8 suggestions to ensure that KPIs are actionable and impactful.

  1. Align with business objectives

  2. Focus on relevance and simplicity

  3. Set measurable targets

  4. Collect accurate and timely data

  5. Visualize your KPIs

  6. Regularly review and update

  7. Add context

  8. Drill down

Actionable KPIs are vital for measuring performance and achieving results. You can drive your business forward by aligning data with goals and simplifying and visualizing KPIs effectively

Blue vs. Green - What does it mean?

No comments

When I first started using #Tableau, I assumed that blue meant dimensions and green meant measures. They don’t.

Blue means Discrete
Green means Continuous

It took me a couple of years to get my head around this most foundational concept in Tableau.

Dimensions and measures are merely a way that Tableau organizes the data.

And if you only take away one thing from this video, this is it:

  • Blue things GROUP your data
  • Green things COUNT your data
  • Dimensions SPLIT up the view
  • Measures FILL the view
I've spent years teaching people what blue and green mean in Tableau and I keep coming up with new methods. In this video, I’ll explain the entire concept to you.

#MakeoverMonday 2023 Week 26: The UK's Drinking Culture

No comments
This week I delve into drinking, a topic that has long been integral to British culture. 

We covered lots during the live stream. I started by attempting to recreate the original, but couldn't get it to work. I went on to build:

1. Stacked bars
2. Stacked bars with labels above the bars (there are a few neat tricks in this one)
3. Circle on a dotted line
4. Donut chart, bar chart combination chart
5. Bullet graphs
6. A mobile view that's a different sheet

Building the mobile view hopefully showed everyone how to leverage sizing objects in a dashboard. If you haven't watched, I created a 2nd sheet that I could format separately to fit on a mobile device. To the user, it would look like the same chart.

The trick is to float the 2nd sheet and make it 1x1 size. Because it's on the dashboard, you can then use the sheet in the mobile view. Check it out, you'll like it.

I'm pretty happy with where I got to in the end. Enjoy the live stream and check out the viz below or here.
