Graph Window
accumulation ignores the summary interval and
continues for the displayed timespan.
• Accumulate with reset - Adds the value of each
reading to the sum of the previous readings. This
accumulation continues for only the duration of the
summary interval. The accumulation resets at the start
of each summary interval. The graph displays the
accumulated value for each interval if there are seven or
fewer summary intervals for the timespan.
The Accumulate statistical functions display a data point
for each reading, This differs from the other statistical
functions, which only display one point for each summary
interval.
When using the Accumulate functions, deselecting the
Display summary check box is recommended. Otherwise
the Display summary will report the total of all
accumulated readings.
Note that accumulating a flow rate does not produce a
total volume for the timespan or summary interval. To
accumulate volumes from a flow rate, first apply a
volume conversion, then calculate a data set containing
the volume data. Then, add the volume data set and
apply the accumulate function.

Displays the site name and data set used as the source. You can
change the source by typing in the name of another site and data
set, or click the Select… button to browse for a source.
The data type buttons allow you to select edited readings or
original values from the database. When the Zero error data
option is selected, the graph will go to zero when an error is
encountered, rather than drawing a straight line from the last
valid reading to the next valid reading.
This box contains three options:
• Standard time - The graph will show the data and its
time stamp as it is stored in the database.
• Shift time - The graph will shift the time stamp of the
data forward or backward by the amount entered.
• Absolute - Translates the time stamp of the data to an
absolute time and date. The readings in the data set,
beginning with the Start Time entered on the Time Scale
tab, will be moved to the absolute date and time
specified.
When a graph or table is active on the Flowlink desktop, clicking
the button will generate a scatter plot using the first two
series defined in the Series tab of the Graph Properties window.
The first series data is plotted against the Y-axis, the second
