QwtLegend orientation on QwtPlot

[bday1223]

I've created a multi-curve QwtPlot with a legend as a child of the canvas at the top, but the legend items are all strung out on a single line across the top of the plot.

// add a legend
QwtLegend* legend = new QwtLegend();
legend->setParent( canvas() );
insertLegend( legend, QwtPlot::ExternalLegend );

I'd like to see each item on its own line; i.e. arranged vertically down the left side of the plot.
Can this be done?

Thanks,
bd
