Manual page for Gallery_-_Line_plots(PL)
This page contains a series of lineplot examples
illustrating the available varieties and options.
These examples all use ploticus's
Example 1 - lines prefab
The lines prefab
is the easiest way to create basic line plots without writing any script code.
Example 2 - script
Simple example. Both X and Y come from data fields.
Example 3 - script
This example plots cpu utilization data produced by the sar(1) utility.
Example 4 - script
Stock price / volume display. The data are read from a file.
Example 5 - script
This example is a comparison of two values over time,
and displays the curves as step values. Step values are used where
interpolation between samples is not appropriate,
or for stylistic reasons. Use the stairstep option.
Y values are shown at each step as well (numbers option.
Example 6 - script
Another example where stairstep mode is used.
This example is also available with a transparent background.
Example 7 - script
This example uses proc lineplot with instancemode
and accum options,
to count occurrances over time. Occurrances having the same date
are summed into one data point (using groupmode).
This allows display of event data without having to tabulate first.
The data must be presented in chronological order.
Example 8 - script
A lineplot with symbols marking the points.
Use the pointsymbol attribute.
Note that the points where lines meet is denoted by a special symbol,
using the altsym and altwhen options.
Example 9 - script
Characters within the point symbols.
The characters comes from a data field.
Use the pointsymbol and pointlabelfield attributes.
Example 10 - script
Y value shown at selected points. Use numbers option, and
the pointlabelrange attribute to control the range where
the labels will appear.
Example 11 - script
In this example, proc lineplot is invoked twice, first to do
the filled area using the fill option, and then again to do
the red line. The Y axis grid is done last so that it is on top
of everything else.
Example 12 - script
Same as above, with a portion of the area highlighted.
proc lineplot is invoked three times, first to do
the filled area using the fill option,
second to do the highlight area,
and third to do the red line.
The Y axis grid is done last.
Example 13 - script
Another example with more data points.
Example 14 - script
Here, two lineplots with points denoted by geometric symbols
are plotted along with three curves with filled area underneath.
Example 15 - script
In this example, ploticus accumulates individual values to
produce cumulative lines. This example also illustrates
using drawcommands to draw the straight goal lines.
