    green color is time. and it means:

    time | value
    0001 | 0003
    0002 | 0002
    0003 | 0004
    0004 | 0007
    0005 | 0001
    You have 4 Byte time, 4 Byte value and so on.
    Read them and append each to a QVector<double> and use
    QwtPlotCurve::setSamples (const QVector< double > &xData, const QVector< double > &yData)
    to plot it.
