Example #1

File: graphviewsequence.cpp Project: EKhilkevitch/scigraphics

{
  if ( Begin == End )
    return;

  if ( Scales.numberToFractionX((End-1)->x()) < 0 )
    return;
  if ( Scales.numberToFractionX(Begin->x()) > 1 )
    return;

  checkIsLessThan Checker(Scales);
  sequence::data::iterator BeginVisbile = Checker(0,*Begin)   ? Begin : std::lower_bound( Begin,        End, static_cast<fcoord>(0), Checker );
  if ( BeginVisbile != Begin )
    --BeginVisbile;
  sequence::data::iterator EndVisible   = Checker(*(End-1),1) ? End   : std::upper_bound( BeginVisbile, End, static_cast<fcoord>(1), Checker );
  if ( EndVisible != End )
    ++EndVisible;
