QCPRange::QCPRange ( )

Constructs a range with lower and upper set to zero.

QCPRange::QCPRange	(	double	lower,
		double	upper
	)

To jest metoda przeciążona, udostępniona dla wygody. Różni się od powyższej metody tylko zestawem akceptowanych argumentów.

Constructs a range with the specified lower and upper values.

The resulting range will be normalized (see normalize), so if lower is not numerically smaller than upper, they will be swapped.

QCPRange QCPRange::bounded	(	double	lowerBound,
		double	upperBound
	)		const

Returns this range, possibly modified to not exceed the bounds provided as lowerBound and upperBound. If possible, the size of the current range is preserved in the process.

If the range shall only be bounded at the lower side, you can set upperBound to QCPRange::maxRange. If it shall only be bounded at the upper side, set lowerBound to -QCPRange::maxRange.

double QCPRange::center ( ) const

inline

Returns the center of the range, i.e. (upper+lower)*0.5

bool QCPRange::contains ( double value ) const

inline

Returns true when value lies within or exactly on the borders of the range.

void QCPRange::expand ( const QCPRange & otherRange )

To jest metoda przeciążona, udostępniona dla wygody. Różni się od powyższej metody tylko zestawem akceptowanych argumentów.

Expands this range such that otherRange is contained in the new range. It is assumed that both this range and otherRange are normalized (see normalize).

If this range contains NaN as lower or upper bound, it will be replaced by the respective bound of otherRange.

If otherRange is already inside the current range, this function does nothing.

void QCPRange::expand ( double includeCoord )

To jest metoda przeciążona, udostępniona dla wygody. Różni się od powyższej metody tylko zestawem akceptowanych argumentów.

Expands this range such that includeCoord is contained in the new range. It is assumed that this range is normalized (see normalize).

If this range contains NaN as lower or upper bound, the respective bound will be set to includeCoord.

If includeCoord is already inside the current range, this function does nothing.

QCPRange QCPRange::expanded ( const QCPRange & otherRange ) const

To jest metoda przeciążona, udostępniona dla wygody. Różni się od powyższej metody tylko zestawem akceptowanych argumentów.

Returns an expanded range that contains this and otherRange. It is assumed that both this range and otherRange are normalized (see normalize).

If this range contains NaN as lower or upper bound, the returned range's bound will be taken from otherRange.

QCPRange QCPRange::expanded ( double includeCoord ) const

To jest metoda przeciążona, udostępniona dla wygody. Różni się od powyższej metody tylko zestawem akceptowanych argumentów.

Returns an expanded range that includes the specified includeCoord. It is assumed that this range is normalized (see normalize).

If this range contains NaN as lower or upper bound, the returned range's bound will be set to includeCoord.

void QCPRange::normalize ( )

inline

Makes sure lower is numerically smaller than upper. If this is not the case, the values are swapped.

bool QCPRange::operator!= ( const QCPRange & other ) const

inline

QCPRange & QCPRange::operator*= ( const double & value )

inline

Multiplies both boundaries of the range by value.

QCPRange & QCPRange::operator+= ( const double & value )

inline

Adds value to both boundaries of the range.

QCPRange & QCPRange::operator-= ( const double & value )

inline

Subtracts value from both boundaries of the range.

QCPRange & QCPRange::operator/= ( const double & value )

inline

Divides both boundaries of the range by value.

bool QCPRange::operator== ( const QCPRange & other ) const

inline

QCPRange QCPRange::sanitizedForLinScale ( ) const

Returns a sanitized version of the range. Sanitized means for linear scales, that lower will always be numerically smaller (or equal) to upper.

QCPRange QCPRange::sanitizedForLogScale ( ) const

Returns a sanitized version of the range. Sanitized means for logarithmic scales, that the range won't span the positive and negative sign domain, i.e. contain zero. Further lower will always be numerically smaller (or equal) to upper.

If the original range does span positive and negative sign domains or contains zero, the returned range will try to approximate the original range as good as possible. If the positive interval of the original range is wider than the negative interval, the returned range will only contain the positive interval, with lower bound set to rangeFac or rangeFac *upper, whichever is closer to zero. Same procedure is used if the negative interval is wider than the positive interval, this time by changing the upper bound.

double QCPRange::size ( ) const

inline

Returns the size of the range, i.e. upper-lower

bool QCPRange::validRange	(	double	lower,
		double	upper
	)

static

Checks, whether the specified range is within valid bounds, which are defined as QCPRange::maxRange and QCPRange::minRange. A valid range means:

range bounds within -maxRange and maxRange
range size above minRange
range size below maxRange

bool QCPRange::validRange ( const QCPRange & range )

double QCPRange::lower

const double QCPRange::maxRange = 1e250

static

Maximum values (negative and positive) the range will accept in range-changing functions. Larger absolute values would cause errors due to the 11-bit exponent of double precision numbers, corresponding to a maximum magnitude of roughly 1e308.

Ostrzeżenie: Do not use this constant to indicate "arbitrarily large" values in plotting logic (as values that will appear in the plot)! It is intended only as a bound to compare against, e.g. to prevent axis ranges from obtaining overflowing ranges.

const double QCPRange::minRange = 1e-280

static

Minimum range size (upper - lower) the range changing functions will accept. Smaller intervals would cause errors due to the 11-bit exponent of double precision numbers, corresponding to a minimum magnitude of roughly 1e-308.

Ostrzeżenie: Do not use this constant to indicate "arbitrarily small" values in plotting logic (as values that will appear in the plot)! It is intended only as a bound to compare against, e.g. to prevent axis ranges from obtaining underflowing ranges.
