--> <div class="descr"> <h2 id="details">Detailed Description</h2> <p>The <a href="qvboxplotmodelmapper.html">QVBoxPlotModelMapper</a> is a vertical model mapper for box plot series.</p> <p>Model mappers enable using a data model derived from the QAbstractItemModel class as a data source for a chart. A vertical model mapper is used to create a connection between a data model and a <a href="qboxplotseries.html">QBoxPlotSeries</a> object, so that each column in the data model defines a box-and-whiskers item and each row maps to the range and three median values of the box-and-whiskers item.</p> <p>Both model and series properties can be used to manipulate the data. The model mapper keeps the series and the data model in sync.</p> <p>The model mapper ensures that all the bar box-and-whiskers items in the box plot series have equal sizes. Therefore, adding or removing a value from a box-and-whiskers item causes the same change to be made in all the box-and-whiskers items in the box plot series.</p> </div> <p><b>See also </b><a
