I think that the PLOTS procedure will do what you want.
You can also use it to draw linestyles on the legend.

Example:

; If this is a line plot
; Draw linestyle on legend
; Endif else
; Draw symbol on legend
; Endelse

if jsym eq 0 then begin
plots, [xoff+xl,xoff+xr], [ypt,ypt], linestyle=jlin, color=jcol
endif else begin
plots, xoff+xl+xseg*0.22, ypt, psym=jsym, symsiz=sym_size, color=jcol
endelse

[This code uses DATA coordinates; I've never tried NORMAL.]

It would be nice if there were a system routine for drawing legends,
though.
