More countries on one graph possible? (Missing Germany & US for example)

[drooog]

Hey. I'm tracking germanys development in comparison with other countries. I see its combined with Sth Korea, Italy and China on a dedicated page. Is it possible to see Germany either added to the main round-up graph your updating? (well aware you don't want to crowd it out though of course).. or a way to add/remove countries? (well aware thats probably more work than you'd appreciate ;-)

Anyhow... appreciate the work your doing there! Thanks!
