This is a box plot (plot type <a class="link" href="conc-plottypes.html#plottype-boxes" title="3.4.3. Plot Type: boxes (Box Plot)">boxes</a>).
Unlike the previous example (<a class="xref" href="ex-boxplot1.html" title="5.50. Example - Box Plot with Data Reduction">Section 5.50, &#8220;Example - Box Plot with Data Reduction&#8221;</a>) the data array
is already processed, and includes the 5 values that make up each row for a
box plot (<code class="literal">Ymin, YQ1, Ymid, YQ3, Ymax</code>) and some
additional <span class="emphasis"><em>outlier</em></span> points.
This example also shows how colors and line styles can be applied to a box
plot.
</p><p>
Note: Box plots were added in PHPlot-6.1.0.
