Gallery - Bars (horizontal)


Welcome     Gallery     Handbook


Manual page for Gallery_-_Bars_(horizontal)(PL)

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. Clickmaps are supported for horizontal bar graphs.


Example 1 - script

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 - script

hbars2

Here, the category labels are within the bars.



Example 3 - script

hbars3

Stacked horizontal bars.



Example 4 - script

hbars5

Clustered horizontal bars.



Example 5 - script

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 - script

distrib

Histograms.



Example 7 - script

timeline1

In this example, bars are used to represent time segments, showing the phases of a project. Use the segmentfields attribute.



Example 8 - script

timeline1a

Same as above, but with differnt colored bars.



Example 9 - script

timeline2

Another time line example. proc scatterplot was used to render the target date points.



Example 10 - script

sess2

Another time line example showing login sessions for one day.



Example 11 - script

clickmap_time2

An example of a timetable. This also illustrates the use of clickmaps with bar graphs. Try clicking on any TV show box above..



Example 12 - script

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.
