Hi.

How to remove space between axis and graph.
See attached file.

I am using qwt-6.0.1 ...

Thanks, BasY

QwtPlotCanvas* canvas = dynamic_cast<QwtPlotCanvas*>( plot->canvas() );
canvas->setFrameStyle( QFrame::Box );
canvas->setLineWidth(1);
 
plot->plotLayout()->setAlignCanvasToScales( true );
for ( int i = 0; i < QwtPlot::axisCnt; i++ )
{
    plot->axisWidget(i)->setMargin( 0 );
    plot->axisScaleDraw(i)->enableComponent( QwtScaleDraw::Backbone, false );
}

QwtPlotCanvas* canvas = dynamic_cast<QwtPlotCanvas*>( plot->canvas() );

    plot->axisScaleDraw(i)->enableComponent( QwtScaleDraw::Backbone, false );
}

To copy to clipboard, switch view to plain text mode 

When playing with those parameters you might find your type of alignment.
