IV.7.4 How to Compare Data
Data sets can be compared using the comparison tab. A user can open up to eight data sets for
comparison by double-clicking on the open slots and selecting a data set from the database.
Graphs as well as tabular data can be created to show the comparison of like output parameters.
Forexample,iftheuserwantstocomparetheowfunctiongraphofmanydatasets,onlyow
function test sets can be selected.

Comparisonsbetweendatalesaredoneusingoneconditionfromeachle.Thereareseveral
output parameters to consider. For example, only the Time consolidated values from a Time
ConsolidatedFlowFunctiontestarecomparedtootherles.Theinstantaneousvaluesforthe
Time Consolidated Flow Function test are not used in the comparison.
a) FlowFunctionCurves:
• For Flow Function Test data, the regular Flow Function curve is used for comparisons.
This reports the gradient, intercept, critical stresses, and Flow Index based on this
Flow Function.
• ForTimeConsolidatedFlowFunctionTestdata,thetimeconsolidatedowcurveis
used for comparisons. This reports the gradient, intercept, critical stresses, and Flow
Index based on this Time Consolidated Flow Function. If you want to compare the
instantaneous and time curves within a single Time Test data set, you can do so in
the Analysis section.
• Wall Test data: Not applicable.
• Density data: Not applicable.
b) FrictionAngleCurves:
• For Flow Function Test data, the Internal Friction Angle curve is used for comparisons.
This reports the Internal Angles at critical stresses based on this curve.
• For Time Consolidated Flow Function Test data, the Time Consolidated Internal
