Tinkering with chart variants...

As I try to tidy up automated chart generation for pushing race reports to Gitbook - - I've also started tinkering with some new charts, such as this variant on the chart to compare the qualifying performance of drivers in the same team which looks at how the drivers in all the teams compared in the qualifying session of a single race:

I'll try to start pushing some of the code to updated chapters in the Wrangling F1 Data With R book too, time allowing... Another reason to buy into that book now is that at some point I want to make a start on a second edition, with a focus on Tidyverse recipes rather than the rather more old-fashioned R the current book contains. Because LeanPub now charge to create new books (at least until an author generates $10k in sales), the new edition will replace the old one at the same URL. (So if you buy now, you'll get the first edition and the second one - if I can find the time to do it! - for one purchase: the LeanPub model means you get all updates for free...)

Initial Peak at Some WRC Telemetry Data

A few weeks ago I was tipped off that telemetry feeds for WRC rally stages were available on the WRC Plus site, so I had a peak and now I'm starting to have a play...

For example, here's a fragment from Rally Sweden 2018 SS9, Meek vs Ogier, looking at throttle, brake and speed:

Here's where it seems to be on the map...

Not sure what do now, though.... What sorts of thing would be interesting to look for from a rally sports reporter perspective?

And what sorts of thing do the teams look for?

F1 2017 Italy Race Review

Pit Activity:

Hmm, looking at that chart, I think I need to: extend the lap range to the duration of the race; in the stacked bar below, order the stacked bars so the stops are ordered left to right; provide an option to rearrange the driver order to rank drivers according to the preliminary classification.
