    Default Broken curve simpleplot

    Example simleplot.
    Modify points (2 and 3 set value to NAN).
    points << QPointF( 0.0, 4.4 ) << QPointF( 1.0, 3.0 )
    << QPointF( 2.0, NAN ) << QPointF( 3.0, NAN )
    << QPointF( 4.0, 7.9 ) << QPointF( 5.0, 7.1 );
    I have very strange curve (lines going to the upper left corner. ).

    If set pen width to 1 - the line looks right.

    how to make the line correct for a different pen width (as with thickness 1 )?

    NAN is no valid coordinate

    I also want there to be no curves in these coordinates, what value should I put here instead of nan?
