\brief A class which draws a scale inside the plot canvas
QwtPlotScaleItem can be used to draw an axis inside the plot canvas.
It might by synchronized to one of the axis of the plot, but can
also display its own ticks and labels.
It is allowed to synchronize the scale item with a disabled axis.
In plots with vertical and horizontal scale items, it might be
necessary to remove ticks at the intersections, by overloading
updateScaleDiv().
The scale might be at a specific position (f.e 0.0) or it might be
aligned to a canvas border.
\par Example
The following example shows how to replace the left axis, by a scale item
at the x position 0.0.
\verbatim
QwtPlotScaleItem *scaleItem =
new QwtPlotScaleItem(QwtScaleDraw::RightScale, 0.0);
scaleItem->setFont(plot->axisWidget(QwtPlot::yLeft)->font());
scaleItem->attach(plot);
plot->enableAxis(QwtPlot::yLeft, false);
\endverbatim
