Additonal arguments for generic plot. Can be used to set xlims, change colors, line widths, etc |

The default plot uses the fraction of L1 norm as the xvar. For forward stagewise and LAR, coefficients can pass through zero during a step, which causes a change of slope of L1 norm vs arc-length. Since the coefficients are piecewise linear in arc-length between each step, this causes a change in slope of the coefficients.

plotting forward stagewise and LAR coefficients against L1 norm, and the
solution we have implemented.
