|
|
|
3 |
<code class="function">SetPointSizes</code> assigns a point size to each data
|
|
|
4 |
set in a plot.
|
|
|
5 |
'Point' here refers to the marker drawn at each data point in 'points' and
|
|
|
6 |
'linepoints' type plots.
|
|
|
7 |
For example, if each data row contains 4 Y values, the first
|
|
|
8 |
point size will be used for the first Y value, the second point size for
|
|
|
9 |
the second Y value, etc.

|
|
|
11 |
An array of point sizes, or a single value. All values are in pixels.
|
|
|
12 |
If a single value, that size is used for all data sets.
|
|
|
13 |
If an array, the array values are the sizes for each subsequent
|
|
|
14 |
data set in a plot.

</p></dd></dl></div></div><div class="refsect1"><a id="idp1378690692"></a><h2>Notes</h2><p>
|
|
|
16 |
If an array is used for <em class="parameter"><code>$ps</code></em>, it
|
|
|
17 |
must use zero-based sequential integer indexes.
|
|
|
18 |
</p><p>
|
|
|
19 |
This applies only to 'points' and 'linepoints' plot types.

PHPlot duplicates the entries in the shorter of the two arrays,
|
|
|
22 |
point sizes and point shapes (set by <a class="xref" href="SetPointShapes.html" title="SetPointShapes"><span class="refentrytitle">SetPointShapes</span></a>),
|
|
|
23 |
to make both arrays the same size. Then it uses the entries in order,
|
|
|
24 |
restarting at the beginning, for each data set at each X value.
|
|
|
25 |
For example, if point sizes is (6, 10), and point shapes is ('diamond',
|
|
|
26 |
'dot', 'rect'), then PHPlot first extends point sizes to (6, 10, 6) to
|
|
|
27 |
match the point shapes. If there are 4 data sets to plot, PHPlot draws the
|
|
|
28 |
point markers at each X value as: diamond (size 6), dot (size 10),
|
|
|
29 |
rect (size 6), diamond (size 6).
|
|
|
30 |
</p><p>
|
|
|
31 |
By default, all point sizes are 6 pixels.

|
|
|
33 |
Through PHPlot-5.0.7, the default size array was (5, 5, 3). However, there
|
|
|
34 |
were bugs in processing the sizes of the point shapes and point sizes arrays.
|
|
|
35 |
Also, for some point sizes, PHPlot rounded the size up to the next even number.
