Changing Chromatogram View Settings
You can change trace display attributes and other run view settings in the System
Control window. Changes you make to the following settings are saved and used in
the display of subsequent runs:
 Trace Show/Hide state
 Trace color
 Trace y-scale range (Min/Max y values)
 Active x-scale units
 Show/Hide state of events, fractions, errors, and annotations
Delta Col
Pressure Column Switching Valve Available when at least one column switching
valve is present
Tip: When two or more column switching
valves are present, the traces appear in
different shades of blue on the
chromatogram. The trace number
corresponds to the valve number in the fluidic
scheme. For example,

Col Pressure 1 in the
legend and the chromatogram corresponds
to C1 in the fluidic scheme.
