qwt 6.1.0 - QwtPlotMarker label truncated by edge of plot

[csteury]

Hello, I have created a label for a QwtPlotMarker. The vertical line is near the right edge of the plot and is truncated by the right edge of the plot/canvas.

How can I make the plot take into account the label and make the plot a bit bigger? Struggling along I tried this:
m_wa_marker->setItemAttribute(QwtPlotItem::Margins, true); // more space???

Thanks in advance for your suggestions (btw - great library!)

cs

QwtPlotMarker *m_wa_marker;
void emat_attenuation_plot::set_wa_sample(double sample)
{
	QString label = QString("WA: %1").arg(sample, 0, 'f', 1);
	QwtText text(label);
	text.setColor(Qt::blue);
	text.setFont(QFont("Helvetica", 10, QFont::Bold));
	m_wa_marker->setLabel(text);
	m_wa_marker->setValue(sample, 0.0);
	m_wa_marker->setItemAttribute(QwtPlotItem::Margins, true); // more space???
}

QwtPlotMarker *m_wa_marker;
void emat_attenuation_plot::set_wa_sample(double sample)
{
	QString label = QString("WA: %1").arg(sample, 0, 'f', 1);
	QwtText text(label);
	text.setColor(Qt::blue);
	text.setFont(QFont("Helvetica", 10, QFont::Bold));
	m_wa_marker->setLabel(text);
	m_wa_marker->setValue(sample, 0.0);
	m_wa_marker->setItemAttribute(QwtPlotItem::Margins, true); // more space???
