Trend Graph.
Trend graphs allow the measurement data from multiple records to be
compared to investigate any trends in the information. Any parameter can
be chosen for the X-axis, and any two other numerical parameters for the
Y1 and Y2 axes.
Size graphs
The following size graphs can be inserted.
Result
This shows the size result of the measurement. It can be displayed in
different ways using its properties box.
Correlogram
Displays the correlation function, which is the output of the contents of
each of the correlation channels.
Residuals
This is the plot of the difference between the actual correlation function
measured and the correlation function that is back calculated from the size
distribution displayed.
Statistics
The statistics graph will show the mean, standard deviation, maximum and
minimum of a group of selected measurement records. The statistics
shown on the table can be altered using the properties dialogue.
Fit
This is an overplot of the actual correlation function measured and the
correlation function that is back calculated from the size distribution
displayed. The closeness of the fit is an indicator of the success of the
algorithm used and the quality of the measurement.
Cumulants fit
Plots the difference between the correlation data and the polynomial that is
the best fit to that data.
Cumulants residuals
Shows a plot of the difference between the cumulants fit and the
measurement data.
Z Average trend
Shows a plot of the Z-average against selected records.
