Thanks - that did the trick - awesome..

I now added a label to the Y-axis and that shifts the graph to
the right. I assumed I needed to subtract out the label portion
but the labelSz.height() value alone isn't sufficient to get the
2 graphs aligned..

What am I missing?



// Get the Y-axis label component to subtract out from the extent
scaleWidget = Simulation_Graph->axisWidget(QwtPlot::yLeft);
QwtScaleDraw *sd = scaleWidget->scaleDraw();
QSize labelSz = sd->labelSize(scaleWidget->font(),
QwtPlot::yLeft);

scaleWidget = Status_Graph->axisWidget(QwtPlot::yLeft);
sd = scaleWidget->scaleDraw();
sd->setMinimumExtent(0);

const int extent = sd->extent(
QPen(Qt::black, scaleWidget->penWidth()),
scaleWidget->font() ) - labelSz.height();
if ( extent > maxExtent )
maxExtent = extent;

scaleWidget = Simulation_Graph->axisWidget(QwtPlot::yLeft);
scaleWidget->scaleDraw()->setMinimumExtent(maxExtent);
