You can expand the chromatogram or the fluidic scheme by clicking the arrow in the
upper-right corner of the relevant pane. This is especially useful when viewing a
chromatogram on the touch screen. Events that occur during the run, such as valve
changes or changes in certain parameters, appear as event markers. Error events
such as overpressure appear in red. The view also shows when fractions are
collected and their locations in the selected rack.
The chromatogram has two y axes. The left axis is the primary axis. Its default trace
is UV absorbance. Conductivity is the default trace for the right axis. The
chromatogram also shows the following traces, which are defined in Table 1:
 Single/Multiple UV
 Conductivity
 pH
 Temperature
 Gradient
 Pressure
 Precolumn pressure
 Delta-column pressure
 Flow Rate
