Revamped daily interactive graph

I have spent rather a lot of time this weekend, perhaps far too much time in revamping my daily interactive CET graph. Hopefully I’ve improved how it looks and how it works, as I brush up what Javascript skills I had, although Highcharts is proving very difficult to master at times. It was difficult to get the balance between the number of individual series I could display and the amount of daily data required to do it, too many series and large arrays, meant that the web application was slow to load. I have only populated it with daily data since 1954, I’ll maybe go back further if I can speed up the array building that I do. You can find the interactive version here – you’ll find that clicking on the legend turns on and off the various series that can be displayed.
