    Default How to hide legend for only one curve?

    Hi,

    I have several curves on a plot. But I only need to show some curves' line type or symbol in legend, not all of them. So I have to hide some curve legend.

    I have tried QwtLegend::remove. But dosen't work.

    I appreciate if you can help.

    Qt Code:
    1. curve->setItemAttribute( QwtPlotItem::Legend, true/false );
    To copy to clipboard, switch view to plain text mode
