ReferenceLineStyle

is an option for QuantilePlot and similar functions that specifies the style used for the reference line.

Details

ReferenceLineStyle->g specifies that a graphics directive g should be used to draw the reference line.
ReferenceLineStyle->{g₁,g₂,…} specifies that successive directives g_i should be used cyclically for successive reference lines.
ReferenceLineStyle->None specifies that the reference line should not be drawn.
The directives that can be given include:

	AbsoluteDashing[{w₁,…}]	dashing specification in point sizes
	AbsoluteThickness[w]	line thickness in point size
	Dashing[{w₁,…}]	dashing specification
	Directive[g₁,g₂,…]	composite graphics directive
	GrayLevel[i]	intensity
	Hue[h]	hue
	Opacity[a]	opacity
	Red,Blue, etc.	named colors
	RGBColor[r,g,b]	RGB color
	Thickness[w]	line thickness

Multiple directives can be given for a single reference line using Directive[g₁,g₂,…].

Examples

ReferenceLineStyle is typically a dotted form of PlotStyle:

Use ReferenceLineStyle->None to turn off the reference line:

Specify a specific style for the reference line:

Use Dashing[{}] to get a solid reference line:
