<code class="function">SetPointSizes</code> assigns a point size to each data
set in a plot.
'Point' here refers to the marker drawn at each data point in 'points' and
'linepoints' type plots.
For example, if each data row contains 4 Y values, the first
point size will be used for the first Y value, the second point size for
the second Y value, etc.
    </p></div><div class="refsect1"><a id="idp1378689036"></a><h2>Parameters</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><em class="replaceable"><code>$ps</code></em></span></dt><dd><p>
An array of point sizes, or a single value. All values are in pixels.
If a single value, that size is used for all data sets.
If an array, the array values are the sizes for each subsequent
data set in a plot.
          </p></dd></dl></div></div><div class="refsect1"><a id="idp1378690692"></a><h2>Notes</h2><p>
If an array is used for <em class="parameter"><code>$ps</code></em>, it
must use zero-based sequential integer indexes.
    </p><p>
This applies only to 'points' and 'linepoints' plot types.
    </p><p>
PHPlot duplicates the entries in the shorter of the two arrays,
point sizes and point shapes (set by <a class="xref" href="SetPointShapes.html" title="SetPointShapes"><span class="refentrytitle">SetPointShapes</span></a>),
to make both arrays the same size. Then it uses the entries in order,
restarting at the beginning, for each data set at each X value.
For example, if point sizes is (6, 10), and point shapes is ('diamond',
'dot', 'rect'), then PHPlot first extends point sizes to (6, 10, 6) to
match the point shapes. If there are 4 data sets to plot, PHPlot draws the
point markers at each X value as: diamond (size 6), dot (size 10),
rect (size 6), diamond (size 6).
    </p><p>
By default, all point sizes are 6 pixels.
    </p></div><div class="refsect1"><a id="idp1378693348"></a><h2>History</h2><p>
Through PHPlot-5.0.7, the default size array was (5, 5, 3). However, there
were bugs in processing the sizes of the point shapes and point sizes arrays.
Also, for some point sizes, PHPlot rounded the size up to the next even number.
