  • My Tableau Resources

    During my Datafam London presentation I briefly showed a slide with a screenshot of my RSS reader – my main source of inspiration on everything Tableau. Afterwards I have got several requests to share this list of website.

    Every time I stumble upon an interesting blog (or website with a feed) I add it to my Feedly account.

    For this post I have exported all these links, and I will update it regularly. If you want to share an interesting Tableau/Data/Data Visualization blog, please let me know and I will add (and follow) it!

  • Drill Down in Tight Spaces

    A different way to make drill down possible/usable in a small sheet.

    Sometimes you don’t have all the space to do what you want.

    Or you are almost finished with a dashboard, and suddenly someone mentions: “Wouldn’t it be nice if we could drill down on this chart…” – but the sheet is just too small for another column. There are multiple ways so solve this issue – each with its own pros and cons. Viz-in tooltip (hard to read on larger drill-downs), hiding nearby sheets (tedious), enlarging the row-height (ugly when not drilled-down), misusing totals (even uglier), …

    In this article I describe a different solution – which definitely has its disadvantages, but can be useful in certain situations where the drill down functionality is important.

  • Line-chart: betters ways to compare years

    Line charts are one of the best and popular ways to show how data has developed over time. It’s a simple graph that is familiar to anyone, but the default generated can often be improved – either in Tableau, Excel or any other tool.

    In this blog post I want to show how a relative small change in a line chart can result in a big improvement.

  • Deep Cleaning Barcharts – part 2: Punctuated Bar Chart

    [part of the ‘Datafam London 2024 series]

    In part 1 we took a look at a basic bar chart, and ended with the lollypop chart. A fun chart with one major issue: the dot obfuscates the real datapoint.

    Punctuated Bar Chart

    One solution for it the Punctuated Bar Chart:
    We highlight the end of each bar, instead of enlarging the endpoint.

  • Deep Cleaning Barcharts – part 1: the basics

    [part of the ‘Datafam London 2024 series]

    On DataFam 2024 in London I gave a presentation / workshop on deep cleaning dashboards.

    Why cleaning dashboards?

    • Make it look better ▶ Users want to use it
    • Less clutter on your dashboard ▶ Less clutter in your brain
    • Making your dashboard more actionable ▶ Focusing on what’s important.

    Dashboard cleaning is about: Removing, adding , re-arranging, and replacing stuff. In Tableau, it’s about: Table calculations, extra sheets, changing images, talking to users, being critical to yourself, … Is hard work – and a lot of fun!
