Time Series graph
Time series graphs plot open-ended streams of data. New data appears
at the right, and the whole graph appears to scroll horizontally.
This illustration shows a freeze-frame of a time series graph.

The time series graph is unique among Graphics Server's graph offerings. Unlike
other graphs, it charts open-ended streams of data, rather than finite data
sets. It consists of a dynamic X-Y grid in which points are added one at a time
to the right-hand edge. When the graph reaches the limit of points it can show,
the oldest data begin to drop off the left edge. The time?series graph is the
only graph type that appears to
move on the screen.
A time series graph is ideal for plotting real-time data. You don't need the
data series in hand when you start the graph, so you can plot values as they
arrive from a source.
-
Data points may be represented by symbols or they
may be connected by continuous lines.
-
Time series graphs can chart multiple data sets,
each represented by a line or sequence of symbols.
-
Because time series graphs represent continuous streams
of data constantly updated, they are intended for display on screen rather
than for printing.
Use a time series graph...
-
When you’re collecting data at regular intervals in real time.
-
When you’re displaying stored data retrieved in real time and you want to
emphasize its dynamic nature.
