Menu Commands
functions, Flowlink will round the starting point of the graph to
the nearest hour or to the closest fifteen minute mark if the total
timespan is less than ten hours. When using the Set Home Date/
Time, Flowlink also rounds the starting point as described and
will also round the timespan to the nearest hour.
The timespan can be changed. For the Graph and Editor
windows, enter a new timespan on the Time Scale tab of the
Properties window (see page 115).
Actions>Set Home
Date/Time
When a Graph or Editor window is active on the Flowlink
desktop, selecting Actions>Set Home Date/Time menu option or
clicking the Set Home button “bookmarks” the start date
and time of the graph. This allows you to quickly jump to this
home point from anywhere in the graph.
Actions>Graph/
Table
When a graph or table is active on the Flowlink desktop,
selecting Actions>Graph/Table from the menu, or clicking the
Graph/Table button toggles the appearance of the window
between the graph and table views.
Actions>Properties Selecting Actions>Properties or clicking the Graph
Properties button while a Graph or Table is active on the desktop
opens the Properties window (see page 113). The Properties
window contains the settings that control the appearance.
Actions>Calculate
Data Sets
The Calculate Data Sets option is useful when you need “handson”
control of the summary intervals and statistical functions
(see page 116). Calculate Data Sets should be used when a
statistical function is applied to data and the results are needed
in a subsequent operation. When attempting to perform complex
analyses without this feature, you may find it is difficult to
control the order of execution or specify when recalculated data
or original data should be used.
To illustrate this need, consider a level data set with readings
taken at fifteen-minute intervals. If the data were to be displayed
in two different daily graphs - one graph applying an hourly
summary interval with an averaging statistical function, the
other without - you may find that the average daily levels are
quite different. The first graph averages the 24 hourly data and
the second averages of all the readings. If this series of data were
to be used in another operation, it is important to understand
which data, original or recalculated, Flowlink will use. Calculate
Data Sets give you this hands-on control.
The Actions>Calculate Data Sets menu option takes a snapshot
of the data that appears in the graph or table. When you
calculate a data set, Flowlink adds a site to the workspace. The
name of the site is the same as the graph or table. This site is not
an actual site; it is solely used for data storage.
