Not really an issue - more of a feature observation.
This might not be easy to do, but it would be great if it could be achieved.
Lets say there are 3 countries displayed:
[China, Italy, South Africa]
And their colours are
[blue, orange, green]
Then a 4th country is ticked and added: Iran.
The displayed legend order is alphabetical, and the order is now:
[China, Iran, Italy, South Africa]
and the colours then update to include red at the end:
[blue, orange, green, red]
Which means that
China -> blue -> blue
Iran - > NA -> orange
Italy -> orange -> green
SA -> green -> red
So, by adding 1 country, 2 (or 3 really) countries (in this example) changed their associated colour. This makes it non-trivial for a r00kie user to track a country. If a user thinks: "Ok, Italy is my country of interest... and its orange", then they add some other countries, they might still think: "Italy = orange". N00bs are bad at checking back to the legend.
It would be amazing is countries drawn maintain their colour while on the plot.
But, I know this is non-trivial, and not important.
