Is this style of diagram in common use? The ones in the second half of the article, I mean, showing course length as a function of average speed...? I can't make any sense of it.
Isn't usually the purpose of drawing lines between the data points to let you infer the approximate value of the function inbetween the data points? But here the lines go backwards, giving conflicting values of the function, so how do you read it?
- contravariant 9y agoIt's just a parametric plot showing two values changing over time. I suppose it's not too common for noisy data like this, but parametric plots are pretty common. The reasoning behind it is probably to emphasize that in most cases course length and average speed both increased over time, rather than being correlated.
- jamessb 9y agoIt's a connected scatterplot. There's quite common in certain contexts (e.g. the Phillips curve in Economics). The lines indicate the joined points represent successive measurements. There's a nice paper describing the history and evaluating their effectiveness [1] [1]: https://eagereyes.org/papers/the-connected-scatterplot-for-presenting-paired-time-series https://eagereyes.org/papers/the-connected-scatterplot-for-p...
