QwtPlot how to save/restore zoom settings

[Darent]

A solution that worked for me was saving "zoomRect" and then restoring using "setZoomRect"

QRectF zoomRect()
{
    const QwtScaleDiv &xs = this->axisScaleDiv( QwtPlot::xBottom);
    const QwtScaleDiv &ys = this->axisScaleDiv( QwtPlot::yLeft );
    QRectF rect = QRectF( xs.lowerBound(), ys.lowerBound(), xs.range(), ys.range() );
    return rect;
}
 
void setZoomRect(const QRectF& r)
{
    d->zoomer->zoom(r);
}

QRectF zoomRect()
{
    const QwtScaleDiv &xs = this->axisScaleDiv( QwtPlot::xBottom);
    const QwtScaleDiv &ys = this->axisScaleDiv( QwtPlot::yLeft );
    QRectF rect = QRectF( xs.lowerBound(), ys.lowerBound(), xs.range(), ys.range() );
    return rect;
}

void setZoomRect(const QRectF& r)
{
    d->zoomer->zoom(r);
}
