New ways to visualise time

[Updated for Tableau Conference Europe 2018]

I’m delighted to present “New Ways to Visualize Time at TC Europe in London. The content is based on one of the chapters in my book, The Big Book of Dashboards.

This post contains links to all the resources shared in the session.

The trend line is amazing. It shows peaks and troughs and trends. But if you only ever use trendlines to show time, you are missing insights in your data. What’s the best way to show time in visualisation? I cannot answer that: it depends on your data, the story you want to tell, your audience, and many other things.

CollageWhich way is time?

Time can go up and down as well as left and right. Generally in the West we point forwards or to the right, but that’s not the only way. Check out these:

  1. For further reading on how time is considered in culture and in data, check out this wonderful article, History on the Line, by Stephen Boyd Davies.
  2. Some dataviz goes in unusual directions:
    1. The Nasdaq viewer by WSJ goes forwards
    2. XKCD Global Temperature goes downwards
    3. Mike Cisneros’ Oil v Gold is an excellent Tableau example of vertical time

A history of the trend line

We forget (or don’t know) that even the most common chart types were once ideas waiting to be thought of. Even though we build them every day, timelines were invented. Here are the milestones I highlight in my talk

For more reading, I cannot recommend Cartographies of Time highly enough. It is an amazing book about the history of the timeline.

I also love this fascinating article about time as a dimension in which we find the quote “the mapping of time has made only modest intellectual progress since it was invented 250 years ago.”

  • One of the examples I used is based on US Road Fatalities data. I used that data to create a dashboard that was comeprehensively described and deconstructed in my “Design Month” series of posts in 2014.
  • I wrote about a similar topic for the Huffington Post, “New ways to see time.” It has some other examples.

Hi Andy

This was one of my favourite sessions of the whole conference. It gave me a ton of ideas to take back to my user community. I’ve socialised this post internally.

Thanks again,

Hi Andy,

Attended your session on this topic during Tableau Conference & absolutely loved it! At one point you discussed “hockey-stick” graphs – I am trying to find documentation on creating them but have had no luck 🙁 Any tips on this?

In gratitude,
Veronica

Hi Andy,
