Vertically aligning multiple plots

[Uwe]

There are different ways to implement this - one is to use a QGridLayout for plots and legends. Instead of QwtPlot::insertLegend() you would have to do something like this:

QwtLegend *legend = new QwtLegend;
legend->setMaxColumns( 1 );
 
connect( plot, SIGNAL( legendDataChanged( const QVariant &, const QList<QwtLegendData> & ) ),
    legend, SLOT( updateLegend( const QVariant &, const QList<QwtLegendData> & ) ) );

QwtLegend *legend = new QwtLegend;
legend->setMaxColumns( 1 );
         
connect( plot, SIGNAL( legendDataChanged( const QVariant &, const QList<QwtLegendData> & ) ),
    legend, SLOT( updateLegend( const QVariant &, const QList<QwtLegendData> & ) ) );

To copy to clipboard, switch view to plain text mode
