<hr><a name="_details"></a><h2>Detailed Description</h2>
A class which draws a scale inside the plot canvas.
<p>
<a class="el" href="class_qwt_plot_scale_item.html" title="A class which draws a scale inside the plot canvas.">QwtPlotScaleItem</a> 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.<p>
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 <a class="el" href="class_qwt_plot_scale_item.html#9c32bac1ff73c6527305698792a6edfe" title="Update the item to changes of the axes scale division.">updateScaleDiv()</a>.<p>
The scale might be at a specific position (f.e 0.0) or it might be aligned to a canvas border.<p>
<dl class="user" compact><dt><b>Example</b></dt><dd>The following example shows how to replace the left axis, by a scale item at the x position 0.0. <div class="fragment"><pre class="fragment">
QwtPlotScaleItem *scaleItem =
new QwtPlotScaleItem(QwtScaleDraw::RightScale, 0.0);
scaleItem->setFont(plot->axisWidget(QwtPlot::yLeft)->font());
scaleItem->attach(plot);
plot->enableAxis(QwtPlot::yLeft, false);
