Makeover Monday 2019 Week 18: Space Station Spacewalks

Makeover Monday

The topic of this week’s Makeover Monday is ISS spacewalks. The original chart is from NASA.

What works well?

  • Stacked bar chart makes it easy to compare between U.S. and Russia.
  • Bars are also labelled which helps with comparisons.
  • Colors are distinct.

What could be improved?

  • A legend could be added to make it clearer which color is for which country.
  • Background image is distracting and can be excluded.

What Ryan did:

  • I used the detail data set provided to show the top 25 astronauts by total spacewalk time.
  • Created a bar chart showing the total spacewalk time broken down by individual spacewalks.
  • Colored the bars by space suit used.

What Marc did:

  • Created a diverging bar chart to allow each series to have an equal baseline. Oriented the axis vertically to avoid unintended positive/negative associations with bars above/below a horizontal axis.
  • Used light colours on a dark background in keeping with the space theme.
  • Excluded 2019, as there is only partial data.
  • Added annotations to highlight key events, including the Space Shuttle Columbia disaster and the end of the Shuttle program.
