Isolate issues on Tap Coefficient graph
Last Updated: July 07, 2026
You can use the Tap Coefficients graph to isolate and compare issues that could be related or have something in common. Issues shown on the Tap Coefficient graph can be selected together using a "strumming" action to highlight the related data points. Issues selected together are highlighted on the graph and any other issue that shares a group with one of the selected issues is also highlighted. Issue groups that contain at least one issue selected on the graph are highlighted in the Issues table to help with further investigation.
NOTE: When you select one or more issues on the Tap Coefficients graph, corresponding corrections are also shown on the In-Channel Response graph.

  2. Position the cursor (+) on the graph close to an issue you want to isolate.
  3. Click and drag until a box is drawn around one or more issues of interest. Selected issues are automatically highlighted as the box expands.
