Detailed Description

A coordinate system with different styles (BOX, FRAME)

Constructor & Destructor Documentation

◆ CoordinateSystem()

CoordinateSystem::CoordinateSystem	(	Qwt3D::Triple	blb = `Qwt3D::Triple(0, 0, 0)`,
		Qwt3D::Triple	ftr = `Qwt3D::Triple(0, 0, 0)`,
		Qwt3D::COORDSTYLE	st = `Qwt3D::BOX`
	)

explicit

Constructs a coordinate system with specified boundaries and style.

Parameters

first	Minimum vertex of the coordinate system box
second	Maximum vertex of the coordinate system box
st	Coordinate system style (NOCOORD, BOX, or FRAME)

Destructor

Member Function Documentation

◆ adjustLabels()

void CoordinateSystem::adjustLabels ( int val )

Adjusts the distance between axis labels and axis body for all axes.

Parameters

val	Offset value to fine-tune label positioning

◆ adjustNumbers()

void CoordinateSystem::adjustNumbers ( int val )

Adjusts the distance between axis numbering and axis body for all axes.

Parameters

val	Offset value to fine-tune number positioning

◆ draw()

void CoordinateSystem::draw ( )

overridevirtual

Draws the coordinate system, including grid lines if enabled.

Chooses visible axes automatically when auto-decoration is on, then draws major and minor grid lines as configured.

Reimplemented from Qwt3D::Drawable.

◆ setAutoScale()

void CoordinateSystem::setAutoScale ( bool val = true )

Enables or disables automatic scaling for all axes.

Parameters

val	True to enable auto-scaling, false to disable

◆ setAxesColor()

void CoordinateSystem::setAxesColor ( Qwt3D::RGBA val )

Sets a common color for all axes.

Parameters

val	RGBA color value to apply to all axes

◆ setGridLines()

void CoordinateSystem::setGridLines	(	bool	majors,
		bool	minors,
		int	sides = `Qwt3D::NOSIDEGRID`
	)

Sets grid line visibility.

Parameters

majors	Draw grid between major tics
minors	Draw grid between minor tics
sides	Side(s) where the grid should be drawn

The axis used for tic calculation is chosen randomly from the respective pair. For most cases an identical tic distribution is therefore recommended.

◆ setLabelColor()

void CoordinateSystem::setLabelColor ( Qwt3D::RGBA val )

Sets a common color for all axis labels.

Parameters

val	RGBA color value to apply to axis labels

◆ setLabelFont() [1/2]

void CoordinateSystem::setLabelFont ( QFont const & font )

Sets the font used for axis labels across all axes.

Parameters

font	QFont object to apply to all axis labels

◆ setLabelFont() [2/2]

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

Sets the font used for axis labels across all axes.

Parameters

family	Font family name
pointSize	Font size in points
weight	Font weight (e.g., QFont::Normal, QFont::Bold)
italic	Whether to use italic style

◆ setLineWidth()

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

Sets line width for axes and tic marks.

Parameters

val	Base line width for axes
majfac	Scaling factor for major tic line width
minfac	Scaling factor for minor tic line width

◆ setNumberColor()

void CoordinateSystem::setNumberColor ( Qwt3D::RGBA val )

Sets a common color for all axis numberings.

Parameters

val	RGBA color value to apply to axis numbers

◆ setNumberFont() [1/2]

void CoordinateSystem::setNumberFont ( QFont const & font )

Sets the font used for axis numbering across all axes.

Parameters

font	QFont object to apply to all axis numberings

◆ setNumberFont() [2/2]

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

Sets the font used for axis numbering across all axes.

Parameters

family	Font family name
pointSize	Font size in points
weight	Font weight (e.g., QFont::Normal, QFont::Bold)
italic	Whether to use italic style

◆ setPosition()

void CoordinateSystem::setPosition	(	Qwt3D::Triple	first,
		Qwt3D::Triple	second
	)

Sets the position of the coordinate system box.

Parameters

first	Front-left-bottom corner of the bounding box
second	Back-right-top corner of the bounding box

◆ setStyle()

void CoordinateSystem::setStyle	(	Qwt3D::COORDSTYLE	s,
		Qwt3D::AXIS	frame_1 = `Qwt3D::X1`,
		Qwt3D::AXIS	frame_2 = `Qwt3D::Y1`,
		Qwt3D::AXIS	frame_3 = `Qwt3D::Z1`
	)

Sets the coordinate system style and selects which axes to display in FRAME mode.

Parameters

s	Coordinate system style (NOCOORD, BOX, or FRAME)
frame_1	First axis to display when using FRAME style
frame_2	Second axis to display when using FRAME style
frame_3	Third axis to display when using FRAME style

In BOX mode all 12 axes are drawn. In FRAME mode only the three specified axes are drawn (unless auto-decoration is enabled). NOCOORD disables all coordinate system rendering.

◆ setTicLength()

void CoordinateSystem::setTicLength	(	double	major,
		double	minor
	)

Sets the length of major and minor tic marks for all axes.

Parameters

major	Length of major tic marks
minor	Length of minor tic marks
