    Default is It possible that a plot has both log and linear scales?

    My application demands that if a curve is set log style , and it displays in a log scale way ,while another is set linear which should be displayed in linear scale.
    Does anybody have good suggestion?

    Assuming you are talking about y axes: put a logarithmic scale to the left and a linear to the right. Then:

    Qt Code:
    1. curve1->setYAxis( QwtPlot::yLeft );
    2. curve2->setYAxis( QwtPlot::yRight );
