contains a lower and upper double value and provides convenience input, output and modification functions.

QCPRange::QCPRange  (  ) 
Constructs a range with lower and upper set to zero.
Definition at line 1314 of file qcustomplot.cpp.
QCPRange::QCPRange  (  double  lower, 
double  upper  
) 
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Constructs a range with the specified lower and upper values.
Definition at line 1323 of file qcustomplot.cpp.
double QCPRange::center  (  )  const 
Returns the center of the range, i.e. (upper+lower)*0.5
Definition at line 1341 of file qcustomplot.cpp.
bool QCPRange::contains  (  double  value  )  const 
Returns true when value lies within or exactly on the borders of the range.
Definition at line 1457 of file qcustomplot.cpp.
void QCPRange::expand  (  const QCPRange &  otherRange  ) 
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 otherRange is already inside the current range, this function does nothing.
Definition at line 1364 of file qcustomplot.cpp.
Returns an expanded range that contains this and otherRange. It is assumed that both this range and otherRange are normalized (see normalize).
Definition at line 1379 of file qcustomplot.cpp.
void QCPRange::normalize  (  ) 
Makes sure lower is numerically smaller than upper. If this is not the case, the values are swapped.

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.
Definition at line 1447 of file qcustomplot.cpp.
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 
Returns the size of the range, i.e. upperlower

static 
Maximum values (negative and positive) the range will accept in rangechanging functions. Larger absolute values would cause errors due to the 11bit exponent of double precision numbers, corresponding to a maximum magnitude of roughly 1e308. Since the number of planckvolumes in the entire visible universe is only ~1e183, this should be enough.

Minimum range size (upper  lower) the range changing functions will accept. Smaller intervals would cause errors due to the 11bit exponent of double precision numbers, corresponding to a minimum magnitude of roughly 1e308.
