Unless you're planning on holding the currency, those graphs are irrelevant - what would matter would be short term changes (1-2 days, perhaps). And while USD might still come out better, your graph grossly distorts how this would affect someone wanting to use USD or BTC primarily purchases while holding their assets in CAD.
