To properly layout the axes, it is necessary to specify on which side of the chart they are located. There is already an "Orientation" enum. However, that gives the direction (top-to-bottom, etc.), but not the position. It might become obsolete in the future, since the direction can also be expressed by setting min and max accordingly.
