Ploticus Gallery - Bars (horizontal)
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 proc bars
with the horizontalbars option.
Example 1
hbars1
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.
Example 2
hbars2
Here, the category labels are within the bars.
Example 3
hbars3
Stacked horizontal bars.
Example 4
hbars5
Clustered horizontal bars.
Example 5
hbars4
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.
Example 6
distrib
Histograms.
Example 7
timeline1
In this example, bars are used to represent time segments, showing
the phases of a project. Use the segmentfields attribute.
Example 7a
timeline1a
Same as above, but with differnt colored bars.
Example 8a
timeline2
Another time line example. proc scatterplot was used to
render the target date points.
Example 8b
sess2
Another time line example showing login sessions for one day.
Example 9
timeline3
An example of a timetable.
Example 10
propbars1
Here, the bar segments represent proportions of a whole.
The stackfields 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 propbars2, an example of
vertical proportional bars.
