text: Title: Order, orientation -> transpose ?
  Body: The `orientation` keyword is used to transpose 1d plots and make them vertical.
  
  In the same way, the `order` keyword is used in 2D plots to change the way dims are interpreted.

  I'm not sure this is crucial since you always have to check the consistency between coordinates and data. In addition, this latter keyword can be confused with the matplotlib keyword. Is this one no longer accessible?
  
  Don't you think a global `transpose` keyword would be more appropriate, for both 1D and 2D plots? For 2D plots, a value like "auto" would even try to guess the appropriate orientation depending on coordinates variations along dimensions, and potentially, attributes (lon, lat, time, etc....).
