implements a position-indipendent horizontal axis, based on JKQTPCoordinateAxis (for most of documentation: see JKQTPCoordinateAxis ).
This axis may be draw at a user-supplied position (used e.g. for color bar axes). The axis positioning parameters are supplied via the constructor,or setter methods.
Basically this class overwrites several virtual methods as follows:
If it is paired with another axis, the parameters of that axis have to be given explizitly in the constructor or with setters.
