The United Kingdom crashes out of the European Union on Friday. That means there is no deal to safeguard continuity of trading arrangements, healthcare, air traffic control, security and intelligence deals, &c. Oh, and it will likely wreck the economy. No big deal, Theresa. But what do UK voters think about their leading political parties in this climate? Thankfully Politico is starting to collect some survey data from areas of marginal constituencies, what Americans might call battleground districts, ahead of the eventual next election.
And it turns out the Tories aren’t doing well. Though it’s not like Labour is performing any better, because polling indicates the public sees Corbyn as an even worse leader than Theresa May. But this post is more to talk about the visualisation of the results.
The graphics above are a screenshot where blue represents the Conservatives (Tories) and red Labour. The key thing about these results is that the questions were framed around a 0–10 scale. But look at the axes. Everything looks nice and evenly spread, until you realise the maximum on the y-axis is only six. The minimum is two. It gives the wrong impression that things are spread out neatly around the midpoint, which here appears to be four. But what happens if you plot it on a full axis? Well, the awfulness of the parties becomes more readily apparent.
Labour might be scoring around a five on Health, but its score is pretty miserable in these other two categories. And don’t worry, the article has more. But this quick reimagination goes to show you how important placing an axis’ minimum and maximum values can be.
