<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qboxset.html">QBoxSet</a> class represents one item in a box-and-whiskers chart.</p>
<p>A box-and-whiskers item is a graphical representation of a range and three median values that is constructed from five different values. There are two ways to specify the values. The first one is by using a constructor or stream operator (&lt;&lt;). The values have to be specified in the following order: lower extreme, lower quartile, median, upper quartile, and upper extreme.</p>
<p>The second way is to create an empty <a href="qboxset.html">QBoxSet</a> instance and specify the values using the <a href="qboxset.html#setValue">setValue</a>() method.</p>
<p>See the <a href="qtcharts-boxplotchart-example.html">box-and-whiskers chart example</a> to learn how to create a box-and-whiskers chart.</p>
