Detailed Description

Autoscalable axis with caption.

Axes are highly customizable especially in terms of labeling and scaling.

Constructor & Destructor Documentation

◆ Axis() [1/2]

Axis::Axis ( )

Default constructor.

Constructs an uninitialized axis with default parameters.

Destructor

◆ Axis() [2/2]

Axis::Axis	(	Qwt3D::Triple	beg,
		Qwt3D::Triple	end
	)

Constructs an axis with specified start and end positions.

Parameters

beg	Start position of the axis
end	End position of the axis

Member Function Documentation

◆ draw()

void Axis::draw ( )

overridevirtual

Draws the axis including base line, tics, and label.

Reimplemented from Qwt3D::Drawable.

◆ setLabelColor()

void Axis::setLabelColor ( Qwt3D::RGBA col )

Sets color for the axis label.

Parameters

col	RGBA color value for the label

◆ setLabelFont() [1/2]

void Axis::setLabelFont ( QFont const & font )

Sets the font for the axis label.

Parameters

font	QFont object to use for the axis label

◆ setLabelFont() [2/2]

void Axis::setLabelFont	(	QString const &	family,
		int	pointSize,
		int	weight = `QFont::Normal`,
		bool	italic = `false`
	)

Sets the font for the axis label.

Parameters

family	Font family name
pointSize	Font point size
weight	Font weight
italic	Whether font is italic

◆ setLabelPosition()

void Axis::setLabelPosition	(	const Qwt3D::Triple &	pos,
		Qwt3D::ANCHOR	an
	)

Sets label position in conjunction with an anchoring strategy.

Parameters

pos	Position for the label
an	Anchor strategy for the label

◆ setLabelString()

void Axis::setLabelString ( QString const & name )

Sets the axis label string.

Parameters

name	The label text string

◆ setLineWidth()

void Axis::setLineWidth	(	double	val,
		double	majfac = `0.9`,
		double	minfac = `0.5`
	)

Sets line width for axis and tics.

Parameters

val	Thickness for axis base line
majfac	Relative thickness for axis major tics (majfac*val)
minfac	Relative thickness for axis minor tics (minfac*val)

◆ setMajors()

void Axis::setMajors ( int val )

Sets number of major intervals.

Parameters

val	Number of major intervals (always >= 1)

◆ setMinors()

void Axis::setMinors ( int val )

Sets number of minor intervals.

Parameters

val	Number of minor intervals (always >= 1)

See also: LogScale::setMinors()

◆ setNumberColor()

void Axis::setNumberColor ( Qwt3D::RGBA col )

Sets the color for axis numbers.

Parameters

col	RGBA color value for axis numbers

◆ setNumberFont() [1/2]

void Axis::setNumberFont ( QFont const & font )

Sets the font for axis numbers.

Parameters

font	QFont object to use for axis numbers

◆ setNumberFont() [2/2]

void Axis::setNumberFont	(	QString const &	family,
		int	pointSize,
		int	weight = `QFont::Normal`,
		bool	italic = `false`
	)

Sets the font for axis numbers.

Parameters

family	Font family name
pointSize	Font point size
weight	Font weight
italic	Whether font is italic

◆ setPosition()

void Axis::setPosition	(	const Qwt3D::Triple &	beg,
		const Qwt3D::Triple &	end
	)

Sets the axis position.

Parameters

beg	Start position of the axis
end	End position of the axis

◆ setScale() [1/2]

void Axis::setScale ( Qwt3D::SCALETYPE val )

Sets one of the predefined scaling types.

Parameters

val	Predefined scale type (LINEARSCALE or LOG10SCALE)

Warning: Too small intervals in logarithmic scales lead to empty scales (or perhaps a scale only containing an isolated major tic). Better switch to linear scales in such cases.

◆ setScale() [2/2]

void Axis::setScale ( Scale * val )

Sets a user-defined scale object.

Parameters

val	Pointer to a Scale object. Use with a heap based initialized pointer only. The axis adopts ownership.

◆ setTicLength()

void Axis::setTicLength	(	double	majorl,
		double	minorl
	)

Sets tic length.

Parameters

majorl	Length of major tics
minorl	Length of minor tics

◆ setTicOrientation() [1/2]

void Axis::setTicOrientation ( const Qwt3D::Triple & val )

Sets tic orientation from a Triple vector.

Parameters

val	Orientation vector for tics (will be normalized)

◆ setTicOrientation() [2/2]

void Axis::setTicOrientation	(	double	tx,
		double	ty,
		double	tz
	)

Sets tic orientation from individual components.

Parameters

tx	X component of tic orientation
ty	Y component of tic orientation
tz	Z component of tic orientation
