No, the chart shows how much the dollar has risen against Chinese currency. Note how the Chinese yuan was worth more American money a few years ago (16¢), than it is worth in American money today, (15¢). That is to say, the American dollar is worth MORE against Chinese currency today than a few years ago. The same is true for the next two most important currencies, the euro and the British pound. The dollar is worth more against them now than a few years ago as well. So your whole theory is disproved.
