.ig >>
<p>
This page contains a series of horizontal bar graph, timeline,
and proportional bars examples
illustrating some of the available varieties and options.
These examples all use ploticus's <a href="../doc/bars.html">proc bars</a>
with the <b>horizontalbars</b> option.
<a href="../doc/clickmap.html">Clickmaps</a> are supported for
horizontal bar graphs.
<br>
<br>
<br>
<h3>Example 1</h3>
<a href="hbars1.htm">hbars1<br><img src="hbars1.gif"></a>
<br>
This example shows how horizontal bars
can provide a compact format for displaying
comparison data, especially when the
category labels are long.
It also demonstrates how selected bars may be highlighted
by using a different color.
<br>
<br>
<br>
<h3>Example 2</h3>
<a href="hbars2.htm">hbars2<br><img src="hbars2.gif"></a>
<br>
Here, the category labels are within the bars.
<br>
<br>
<br>
<h3>Example 3</h3>
<a href="hbars3.htm">hbars3<br><img src="hbars3.gif"></a>
<br>
Stacked horizontal bars.
<br>
<br>
<br>
<h3>Example 4</h3>
<a href="hbars5.htm">hbars5<br><img src="hbars5.gif"></a>
<br>
Clustered horizontal bars.
<br>
<br>
<br>
<h3>Example 5</h3>
<a href="hbars4.htm">hbars4<br><img src="hbars4.gif"></a>
<br>
Reflected bar graphs. These are sometimes used to compare two sets of values.
I personally don't like these, except perhaps
when the number of categories is large, or when the
nature of the data lends itself to such a display;
I would prefer two-bar clusters.
<br>
<br>
<a name=timeline></a>
<br>
<h1>Floating segment bars and timelines</h1>
Floating segment bars can represent time intervals, genomic regions, etc.
See also the <a href="http://members.chello.nl/epzachte/Wikipedia/EasyTimeline/Introduction.htm">EasyTimeline</a>
package by Erik Zachte / Wikipedia, which utilizes ploticus.
<br>
<br>
<h3>Example 6</h3>
<a href="segments.htm"><img src="segments.gif" border=0></a>
<br>
<br>
<br>
<h3>Example 7</h3>
<a href="timeline1a.htm">timeline1a<br><img src="timeline1a.gif"></a>
<br>
In this example, bars are used to represent time segments, showing
the phases of a project. Use the <b>segmentfields</b> attribute.
<br>
<br>
<br>
<h3>Example 8</h3>
<a href="timeline2.htm">timeline2<br><img src="timeline2.gif"></a>
<br>
Another time line example. proc scatterplot was used to
render the target date points.
<br>
<br>
<br>
<h3>Example 9</h3>
<a href="sess.htm">sess2<br><img src="sess.gif"></a>
<br>
Another time line example showing login sessions for one day.
<br>
<br>
<br>
<h3>Example 10</h3>
<a href="clickmap_time2.htm">clickmap_time2</a><br>
<a href="clickmap_time2.map"><img src="clickmap_time2.gif" ismap></a>
<br>
An example of a timetable. This also illustrates the use of
<a href="../doc/clickmap.html">clickmaps</a> with bar graphs.
Try clicking on any TV show box above..
<br>
<br>
<br>
<a name=proportion></a>
<h1>Proportions</h1>
<h3>Example 11</h3>
<a href="propbars1.htm">propbars1<br><img src="propbars1.gif"></a>
<br>
Here, the bar segments represent proportions of a whole.
The <b>stackfields</b> attribute is used to position bars.
This is the same type of look that a pie graph shows, but
bars are usually more compact.
See also <a href="propbars2.htm">propbars2</a>, an example of
vertical proportional bars.
