This is a horizontal 'linepoints' plot.
|
|
|
4 |
In a horizontal plot, the Y (vertical) axis is for the independent values,
|
|
|
5 |
and the X axis (horizontal) is for the dependent values, so PHPlot is
|
|
|
6 |
graphing <span class="mathphrase">X = F(Y)</span>.
|
|
|
7 |
</p><p>
|
|
|

This plot has:
|
|
|
9 |
</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
|
|

10 |
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

empty)

</p></li><li class="listitem"><p>

|
|
|
18 |
</p></li><li class="listitem"><p>
|
|
|
19 |
Y data label lines, which connect the data points horizontally to the Y
|

20 |
axis data labels (see <a class="xref" href="SetDrawYDataLabelLines.html" title="SetDrawYDataLabelLines"><span class="refentrytitle">SetDrawYDataLabelLines</span></a>)
