Are major exporter countries to the United States really manipulating their currency to boost exports?

The Euro Area, China, Canada, Mexico and Japan together account for over 70% of U.S. trade. Have these countries (including the Euro Area group of countries) manipulated their currencies to boost exports? In this century (2000 onwards) the Chinese Yuan, the Canadian Dollar and the Euro have appreciated against the dollar. The Japanese Yen has been largely unchanged against the U.S. dollar since the start of this century and only the Mexican Peso has weakened against the dollar.

Here are some graphs,
