col |
vector of size one or two, indicating the colors for representing series x and - if needed -series y in the B-D plane. Default is black for series x and red for series y. |

This function is invoked for its side effect which is to produce a graphical representation of the expansion of a series in its unbalanced Haar wavelet basis. The series is plotted in the plane that is defined by the values of its breakpoints and its detail coefficients. Points are numbered according to their rank in the hierarchy.
Another way to represent the BUUHWE transform of a series is trough function BUUHWE.plot
