Setting up Chart Target Lines

Target lines in APM charts typically illustrate target values or thresholds for reference purposes. For example, a risk tolerance line (or plot line) indicates risk tolerance levels to provide context for failure mode analysis results in strategy development analyses. Other example uses of chart lines are to show heat exchange and pressure flow levels. You can also create chart lines to show marine growth boundaries and platform cathodic protection minimum and maximum readings for display in the Inspection Management view, Analytics tab.

Chart target lines can be defined in indicator, risk, and analytics settings. Whenever a chart target line is created, it is available to all sites in the enterprise.
