<title>Manual page for Gallery_-_Scatter_plots(PL)</title>
37
This page contains a series of scatterplot examples
38
illustrating the available varieties and options.
39
These examples all use ploticus's
40
<a href="../doc/scatterplot.html">proc scatterplot</a>.

<h1><br>The scat1 prefab</h1>
45
<a href="../doc/scat1.html">scat1 prefab<br><img src="../prefabs/scat1b.gif"></a>
47
The scat1 prefab is the easiest way to create basic scatterplots without
48
writing any script code.
52
<h1><br>Example 1</h1>
53
<a href="scatterplot1.htm">scatterplot1<br><img src="scatterplot1.gif"></a>
55
This example shows the correlation between two variables.
56
The 1-D distribution for each variable is shown along each axis.
57
Duplicate data points are offset slightly (the <b>cluster</b>
58
option) to show duplicity.
62
<h1><br>Example 1a</h1>
63
<a href="scatterplot10.htm">scatterplot10<br><img src="scatterplot10.gif"></a>
65
Correlation scatterplot showing regression line and error bars on the points.
68
<h1><br>Example 2</h1>
69
<a href="scatterplot8.htm">scatterplot8<br><img src="scatterplot8.gif"></a>
71
This illustrates how multiple points can be displayed using the clustering option.
72
Size, color, "transparency", and shape of the points are all user-controllable, as is
73
the distance of clustering.
76
<h1><br><br>Example 3</h1>
77
<br><a href="scatterplot3.htm">scatterplot3<br><img src="scatterplot3.gif"></a>
79
Points may be marked with a variety of geometric symbols and characters/text,
80
in a variety of colors. Point symbols may be solid (filled) or transparent
83
<h1><br><br>Example 3a</h1>
84
<br><a href="scatterplot3a.htm">scatterplot3a<br><img src="scatterplot3a.gif"></a>
86
The size of point symbols may be driven by a data field, allowing display of
89
<h1><br><br>Example 4</h1>
90
<br><a href="scatterplot4.htm">scatterplot4<br><img src="scatterplot4.gif"></a>
92
This example demonstrates how points that are outside of the defined plotting
93
area are omitted. Here, the points are not filled with color,
94
making them appear to be transparent.
96
<h1><br><br>Example 5</h1>
97
<br><a href="qual.htm">qual<br><img src="qual.gif"></a>
99
An example showing scores over time. Case identifiers are shown
100
at bottom using a second invocation of <b>proc scatterplot</b>.
103
<h1><br><br>Example 6</h1>
104
<br><a href="scatterplot5.htm">scatterplot5<br><img src="scatterplot5.gif"></a>
106
An example where data text is shown instead of a point symbol.
107
This may be useful in identifying outlier cases.
110
<h1><br><br>Example 7</h1>
111
<br><a href="scatterplot6.htm">scatterplot6<br><img src="scatterplot6.gif"></a>
113
A 1-D scatterplot showing instances over time. Instances are denoted by
114
lines in the top panel, and by names in the bottom panel.
115
1-D distributions usually work better for scattered data points; when there is
116
significant duplication a histogram (bar graph) is more effective.
118
<h1><br><br>Example 8</h1>

<br><a href="multiscat.htm">multiscat<br><img src="multiscat.gif"></a>
121
A full-page example showing an array of scatterplots.
123
<h1><br><br>Example 9</h1>
124
<br><a href="errbar1.htm">errbar1<br><img src="errbar1.gif"></a>
126
In this example, <b>proc scatterplot</b> was used to render the point
127
symbols, and then the error bars were added using <b>proc bars</b>.
130
<h1><br><br>Example 10</h1>

Another full-page example showing multiple scatterplots.
