Selecting the graph tips check box allows the setting of pop up tips (flags
showing data points on the graph). These appear on the report itself (not on the
screen shown in the Report Designer).
Selecting the legend check box places a summary table, showing date and
name, at the foot of each graph.
Tables
A number of data tables can be added to the report. The data is taken from the cur-
rent selected record or, for the Difference and Statistics tables, group of selected
records.
The following data tables can be added:
Data – displays the raw data produced by the system.
Difference – shows the difference between the results in a reference measure-
ment record and the currently selected measurement record.
Data Fit – gives a table showing the fit. This shows the difference between the
actual light energy distribution measured for a sample and the theoretical pre-
diction of the light energy distribution according to the Mie or Fraunhofer
scattering model selected for that material.
The closeness of the fit is an indicator of the correctness of the light scattering
data used and the quality of the measurement (cleanliness of the system, etc.).
Result – shows the raw result data.
Statistics – shows the mean, standard deviation, maximum and minimum of a
group of selected measurement records. The statistic shown on the table can be
altered using the Properties box.
Sieve – presents the data from the current measurement record as it would be
displayed if a stack of sieves had been used for the measurement. A number of
standard sieves can be selected using the Properties box.
Phi – soil scientists often use this size classification to present size data. This
phi notation is based on a power of two series where the class boundaries are
labelled by the index.
Grade efficiency – grade efficiency curves created from particle sizing results
are used to establish the efficiency of separators such as hydrocyclones, sedi-
menting centrifuges or gravitational clarifiers.
The table’s colour, font and number of rows and columns can be altered using its
Properties box.
