  1. Seeq's grouping functionality is helpful when you want to align multiple conditions and signals, but a signal (or set of signals) only applies to a subset of the conditions. Grouping a signal with a condition will only display that signal during the grouped condition. For example, here I have two temperature signals and a condition for each signal. I have used Profile Search to identify the profile for each signal I would like to compare. When I use Chain View or Capsule Time, the default will cause both signals to show up during each capsule. In this Chain View, the information of Reactor Temperature 1 is not relevant during the Profile Reactor 3 condition and vice versa: In order to view only the relevant signal information, I can use the grouping functionality in Chain View and Capsule Time to compare the relevant signals during each condition: 1) Select grouping in the toolbar. 2) Navigate to the grouping icon next to the condition in the details pane and select the signal that corresponds to the condition. Select multiple signals, if necessary. I can also view this in Capsule Time. As an additional option, I can overlay both signals using the One Lane and One Axis selections in the tool bar:
  2. Seeq Version: R21.0.43.03 but the solution is applicable to previous versions as well. The Profile Search Tool is great for specifying a profile in Signal A and then looking for occurrences of that profile throughout time. In the screenshot below I've used Profile Search to identify when the Compressor Power Area A resembles the shape of a chair. For basics about how to use the tool check out the Seeq KB article Profile Search. However, what if I want to look for that same profile on another signal? In the screenshot below, I've added a second signal, Compressor Power Area G. I'd like to identify when the "chair" profile I previously specified for Compressor Power Area A is present in Compressor Power Area G. I can do this by using the profileSearch() function in Seeq Formula. Here is how... 1. Start with the Chair in Area A condition I previously made and use Duplicate to Formula. The duplicated formula looks like (note that $cpA refers to Compressor Power Area A): profileSearch($cpA, toTime("2019-09-02T15:43:30.135Z"), toTime("2019-09-03T06:28:09.629Z"), 98, 0.5, 0.3, 0.3) 2. Modify the formula to add $cpG (Compressor Power Area G) to the start of the function. This is an optional argument in Profile Search which allows us to use the profile identified on signal $cpA and look for when it occurs on signal $cpG. For more information on the Profile Search function, check out the documentation available in the Formula Tool. $cpG.profileSearch($cpA, toTime("2019-09-02T15:43:30.135Z"), toTime("2019-09-03T06:28:09.629Z"), 98, 0.5, 0.3, 0.3) Here is a screenshot of what it looks like in the Formula Tool: 3. View the final result. In this example two "chairs" where identified in Area G.
