I am a big chess fan and play a lot, some games count for my Fide chess rating. The data of the Fide.com chess rating site I have put in 3 personal charts. I have also added the data of the top 10 chess players to put my rating into perspective. That data I put in 3 more charts.
The charts are created using my own fork from ChartsJs and is a big rewrite that started from my pull request BarAndLine Charts. The structure of my fork is different from that of ChartJs master, so a pull request is no longer a option. But maybe some of my changes can be use in the main project.
