how to disable legend of a QwtPlotCurve in Qwt-5.2 ?

[cornucopia]

for one line I don't want to show its legend, how to disable it ? the enableLegend() was deprecated in qwt-5.2.

QwtPlotCurve *maglayout = new QwtPlotCurve();
maglayout->attach(this);

Thanks.

maglayout->setItemAttribute(QwtPlotItem::Legend, false);

setItemAttribute(QwtPlotItem::Legend, false); is not working qwt6. In my case the label text is empty. But still it is showing a color box in legend
