Constructor & Destructor Documentation

Annotation1DVerticalLineItem() [1/3]

Annotation1DVerticalLineItem	(	const double	x_pos,
		const QColor &	color = QColor("as_before"),
		const QString &	text = ""
	)

Constructor for a single vertical line of 1px width.

Parameters

x_pos	X-coordinate as show on the axis
color	Optional color. If invalid (=default), the current painter color will be used when this is painted
text	Optional text displayed next to the line. Can contain ' ' which will force multiple lines.

Annotation1DVerticalLineItem() [2/3]

Annotation1DVerticalLineItem	(	const double	x_center_pos,
		const double	width,
		const int	alpha255 = 128,
		const bool	dashed_line = false,
		const QColor &	color = QColor("as_before"),
		const QString &	text = ""
	)

Constructor for a single vertical line of 1px width or a broader line (band) with the given width

Parameters

x_center_pos	X-coordinate of the center as show on the axis
width	Full width of the band; use 0 or 1 for a 1px line.
alpha255	A transparency value from 0 (not visible), to 255 (fully opaque)
dashed_line	Should the line/band be dashed
color	Optional color. If invalid (=default), the current painter color will be used when this is painted
text	Optional text displayed next to the line/band. Can contain ' ' which will force multiple lines. Text will be plotted at the very top (modify using setTextYOffset())
