Detailed Description

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

---

Constructor & Destructor Documentation

Axis

(

)

Constructs standard axis.

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

Constructs a new axis with specified limits.

---

Member Function Documentation

void draw

(

)

[virtual]

Draws axis.

Reimplemented from Drawable.

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

Positionate axis.

void position	(	Qwt3D::Triple &	beg,
		Qwt3D::Triple &	end
	)			const [inline]

Returns axis' position.

Qwt3D::Triple begin

(

)

const [inline]

Returns axis' beginning position.

Qwt3D::Triple end

(

)

const [inline]

Returns axis' ending position.

double length

(

)

const [inline]

Returns axis' length.

void setTicLength	(	double	majorl,
		double	minorl
	)

Sets tics lengths in world coordinates

void ticLength	(	double &	majorl,
		double &	minorl
	)			const [inline]

Returns tics lengths.

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

Sets tic orientation.

void setTicOrientation

(

const Qwt3D::Triple &

val

)

Same function as above.

Qwt3D::Triple ticOrientation

(

)

const [inline]

Returns tic orientation.

void setSymmetricTics

(

bool

b

)

[inline]

Sets two-sided tics (default is false).

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

Sets font for axis label.

void setLabelFont

(

QFont const &

font

)

Sets font for axis label.

QFont const& labelFont

(

)

const [inline]

Returns current label font.

void setLabelString

(

QString const &

name

)

Sets label content.

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

Sets label position in conjunction with an anchoring strategy

void setLabelColor

(

Qwt3D::RGBA

col

)

Sets color for label.

void setLabel

(

bool

d

)

[inline]

Turns label drawing on or off.

void adjustLabel

(

int

val

)

[inline]

Shifts label in device coordinates dependent on anchor;.

void setScaling

(

bool

d

)

[inline]

Turns scale drawing on or off.

bool scaling

(

)

const [inline]

Returns, if scale drawing is on or off.

void setScale

(

Qwt3D::SCALETYPE

val

)

Sets one of the predefined scaling types.

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.

void setScale

(

Scale *

val

)

This variant sets a user-defined scale object. Use with a heap based initialized pointer only. The axis adopts ownership.

void setNumbers

(

bool

d

)

[inline]

Turns number drawing on or off.

bool numbers

(

)

const [inline]

Returns, if number drawing is on or off.

void setNumberColor

(

Qwt3D::RGBA

col

)

Sets the color for axes numbers.

Qwt3D::RGBA numberColor

(

)

const [inline]

Returns the color for axes numbers

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

Sets font for numbering.

void setNumberFont

(

QFont const &

)

Overloaded member, works like the above function.

QFont const& numberFont

(

)

const [inline]

Returns current numbering font.

void setNumberAnchor

(

Qwt3D::ANCHOR

a

)

[inline]

Sets anchor position for numbers.

void adjustNumbers

(

int

val

)

[inline]

Shifts axis numbers in device coordinates dependent on anchor;.

void setAutoScale

(

bool

val = true

)

[inline]

Turns Autoscaling on or off.

bool autoScale

(

)

const [inline]

actual Autoscaling mode

void setMajors

(

int

val

)

Requests major intervals (maybe changed, if autoscaling is present).

void setMinors

(

int

val

)

Requests minor intervals.

See also:

LogScale::setMinors().

int majors

(

)

const [inline]

Returns number of major intervals.

int minors

(

)

const [inline]

Returns number of minor intervals.

Qwt3D::TripleField const& majorPositions

(

)

const [inline]

Returns positions for actual major tics (also if invisible).

Qwt3D::TripleField const& minorPositions

(

)

const [inline]

Returns positions for actual minor tics (also if invisible).

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

Sets line width for axis components.

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)

double lineWidth

void limits	(	double &	start,
		double &	stop
	)			const [inline]

Returns axis interval.

void recalculateTics

(

)

Enforces recalculation of ticmark positions.
