# S3 method for density draw(object, side=1, height=0.2, offset=0, scale=c("absolute", "relative"), xtrim=NULL, xpd=TRUE, ...)
numericscalar specifying the "height" of the curve, where height means the maximum height of the density. that is, how much the zero-density position should be shifted.
characterspecifying the scale of the curve, which can be either absolute or relative.
