bshow

procedure bshow, [nfit=integer], [ok=variable], [color=color]

Overplot a baseline using the stored coefficients in !g.polyfit and !g.nfit and the data in the primary data container (number of channels only).

Note that bshow does not itself do any fitting. This only show the result of the most recent fit. Since the fitted polynomials are orthogonal, using up to !g.nfit of them is itself a valid fit at the lower order.

Examples

    bshape, nfit=7, /noshow     ; fit a 7th order polynomial
    bshow                       ; show it
    bshow, nfit=5, color=!blue  ; show the 5th order fit

Keywords
nfit in, optional integer	Only use at most nfit parameters. If !g.nfit is less then nfit, then only !g.nfit parameters will be used and a warning will be issued.
ok out, optional variable	This is set to 1 on success and 0 on failure.
color in, optional color (def. !g.oshowcolor)	The color to use for the overplot.
