in the data set properties.) Set the summary interval to
the desired interval for displaying the results on a graph
or a table.
• The operations are executed from left to right, starting
from within enclosed parentheses. Flowlink executes the
exponentiation operations first, followed by
multiplication and division operations, and it then
proceeds with addition and subtraction, working its way
outside of the parentheses.
• Use care to ensure that the data sets are from the same
reading types. The units of measure are assigned by the
first data set.
• Valid formulas will yield the result when you click the
OK button. If Flowlink recognizes a formula error, it
provides a Details>> button to explain the error.

Graph Properties -
Scatterplots
The Scatterplots Tab in the Properties window contains the
settings for a scatterplot graph. In order to generate a scatterplot
graph, first select the Scatter option on the General Tab in the
Properties window, or click the
button in the Graph Toolbar.
The scatterplot graph uses two series defined in the Series tab of
the Graph Properties window. The first series data is plotted
against the Y-axis, the second series data against the X-axis.
By default, the scatterplot graph uses the first two data series
defined in the Series tab of the Graph Properties window. To
select the data to be graphed, highlight “New XY Series” in the
box. Select a data series for X and a data series for Y from the
dropdown lists, and click the Add Plot button.
The settings for appearance and best fit curve appear for
whatever plot is selected in the box:
• Data Point Size - select small, medium, or large.
• Data Point Symbol - select a shape from the dropdown
list
• Data Point Color - select a color from the dropdown list.
• Best Fit Curve - apply a smooth curve to your data by
selecting the Generate Best Fit Curve checkbox.
Understanding
Summary Intervals
Summary intervals provide powerful statistical functions when
manipulating data. The summary interval, when used with the
average, minimum, maximum, or sum functions, will recalculate
the data to the specified interval. When using summary
intervals, Flowlink can recalculate the data for any reading
interval, from one minute to a number of years. The
recommended summary interval will depend on the output
requirements. When selecting a summary interval, you should
consider how often a reading is necessary to produce a
representative plot on a graph, or how often a reading should be
listed in a table.
