详细描述

Autoscalable axis with caption

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

构造及析构函数说明

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

参数

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

成员函数说明

draw()

void Axis::draw ( )

overridevirtual

Draws the axis including base line, tics, and label

重载 Qwt3D::Drawable .

setLabelColor()

void Axis::setLabelColor

(

Qwt3D::RGBA

col

)

Sets color for the axis label

参数

col	RGBA color value for the label

setLabelFont() [1/2]

void Axis::setLabelFont

(

QFont const &

font

)

Sets the font for the axis label

参数

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

参数

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

参数

pos	Position for the label
an	Anchor strategy for the label

setLabelString()

void Axis::setLabelString

(

QString const &

name

)

Sets the axis label string

参数

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

参数

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

参数

val	Number of major intervals (always >= 1)

setMinors()

void Axis::setMinors

(

int

val

)

Sets number of minor intervals

参数

val	Number of minor intervals (always >= 1)

参见

LogScale::setMinors()

setNumberColor()

void Axis::setNumberColor

(

Qwt3D::RGBA

col

)

Sets the color for axis numbers

参数

col	RGBA color value for axis numbers

setNumberFont() [1/2]

void Axis::setNumberFont

(

QFont const &

font

)

Sets the font for axis numbers

参数

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

参数

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

参数

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

参数

val	Predefined scale type (LINEARSCALE or LOG10SCALE)

警告

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

参数

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

参数

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

参数

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

参数

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