I’m not afraid to admit my ignorance; why are they using a green graph line going up to denote that the ruble is going down in value here? The context of the graph seems ambiguous. Is it because that’s actually denoting the value of USD in the equation? Or is the color in this particular instance irrelevant and it’s way too zoomed out to be very useful at a real-time level? I know the ruble is nose diving, so I’m not sure how to read this graph other than “96.41 rubles = 1 USD.”
