The Control Panel
Control Panel: The Trend Plot

When included in a  Control Panel, the Trend Plot provides the ability to monitor impending problems by viewing a plot of module-specific data.

 Tip:

The Dionex Templates > Panels > Wellness directory of the local Datasource includes several examples of control panels with trend plots of module-specific data.

The following commands are available via the context menu (right-click to select a command). The commands allow you to define the appearance of the trend plot.

Flow Change Marks

Displays vertical solid lines on the trend plot to indicate a change in flow rate.

 

 

Eluent Change Marks
