This is a horizontal 'linepoints' plot.
In a horizontal plot, the Y (vertical) axis is for the independent values,
and the X axis (horizontal) is for the dependent values, so PHPlot is
graphing <span class="mathphrase">X = F(Y)</span>.
</p><p>
This plot has:
  </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
Y axis data labels, which show the values from the label positions in the data
array along the Y axis
(see <a class="xref" href="SetYDataLabelPos.html" title="SetYDataLabelPos"><span class="refentrytitle">SetYDataLabelPos</span></a>, not used in the example below
because the default is to plot labels along the Y axis if they are not
empty)
      </p></li><li class="listitem"><p>
X data value labels, which show the X value just above each data point
(see <a class="xref" href="SetXDataLabelPos.html" title="SetXDataLabelPos"><span class="refentrytitle">SetXDataLabelPos</span></a>)
      </p></li><li class="listitem"><p>
Y data label lines, which connect the data points horizontally to the Y
axis data labels (see <a class="xref" href="SetDrawYDataLabelLines.html" title="SetDrawYDataLabelLines"><span class="refentrytitle">SetDrawYDataLabelLines</span></a>)
      </p></li></ul></div><p>
</p><p>
Note: Horizontal linepoints plots were added in PHPlot-6.0.0.
