Associate observations with a secondary characteristic, for example, the operator who
performed the assay, to evaluate at a glance which additional factors might be influencing
your results.
Define the secondary characteristic by adding a floating-point number or a single line
text to your data table, and use this characteristic in a data series to assign a color
to the characteristic.
In the following example, a column 'Operator' is added to the data table and referenced
in the data series to distinguish between the operators Alice and Bob. The monitored
parameter (in this example the potency) is referenced in the same data series.Figure 1. Assignment of data table column to data series for use as a secondary
characteristic
Note: Secondary characteristics are for visualization purposes only. They do not
change the parameter statistics of a data series or chart.
