  1. Hello Yanmin, 1) Currently, there is no way to copy an entire worksheet from one workbench to another. You can see this thread for additional discussion about it: I would advise reporting your use case to support@seeq.com and our Customer Success team can potentially help implement a workaround given Seeq Data Lab and a version prerequisite, as well as get you and your organization linked to the Feature Request for that item. You might also consider using this solution for copying some items from 1 Workbench to another, but keep in mind the scoping of those items remain to the original and they will still be linked (simply a copy, not a clone of the original): 2) Similarly to item #1, the only method to duplicate formulas via the UI is one at time per the method you're showing. Seeq Data Lab and Python would allow you to programmatically copy Formulas though.
  2. When you are evaluating the efficacy of a regression, there a few commons methods. You might simply take the difference between your predicted value and your actual value, then create capsules when this value deviates from some critical magnitude. I'll outline an alternative approach, by calculating the r-squared (r2) value over each capsule (in my case, days), but this can be applied to any condition like batches or a Manual Condition of training and validation. The general outline is: 1. Build a prediction in Seeq using the Prediction tool. You can specify your training window by a condition or simply start and end time. More details in our Knowledge Base article: https://support.seeq.com/space/KB/143163422/Prediction 2. Create a condition in which you want to compare R2 values. In this example, I'll simply use a Periodic Condition of days. 3. Resample your predicted value based on your original value. Seeq's resample function allows an input of another signal, which is particularly critical if your model inputs have varying sample rates. This will eliminate any error that would of otherwise been introduced by oversampling of your prediction and interpolation issues. 4. Calculate the R2 value over the condition from Step #2 using the following Formula. $ym = $signal.aggregate(average(), $days, startkey()).toStep() $total = (($signal-$ym)^2).aggregate(sum(), $days, startkey()) $residual = (($signal-$prediction)^2).aggregate(sum(), $days, startkey()) $r2 = (1-($residual/$total)).toStep() return $r2 You can continue your Analysis by building a Value Search for when your R2 deviates below a given threshold - or summarize your results in your Organizer Topic. Feel free to reach out with any questions or improvement ideas! Happy Seeqing! -Chris O, Seeq Analytics Engineer
  3. Hello Arnaud, We appreciate the suggestion. We have a team dedicated to Seeq Extensibility which I foresee your suggestion being a part of for teams to easily understand the calculation process of analyses. We have a similar feature called "Derived Data", at the bottom of the Tools panel, that shows a dependency tree, in descending order, of all the items in the display. This can be used a quick reference to understand the relationship between all your calculated signals/conditions. -Chris O
  4. Hello Theresa, There's no feature to directly increase resolution of a downloaded PDF from Seeq Organizer. However, you can adjust size of your content as necessary, add page-breaks, and adjust font sizes to re-format your report. Each piece of Seeq content should have the ability to change Content Size and Font Size in the edit modal (Scorecard Metrics will only have Font Size, though) Hope you are able to clarify your PDF download using these tips! -Chris O
  5. Hey Felix, Are you in Capsule Time when you see the duplicate values? This is expected when you're overlaying your capsules/boundaries in Capsule Time. You can turn Cursor Values off through the Labels menu but cannot choose to just show 1 value, even in Capsule Time. Does that answer your question? -Chris O
  6. Felix, To address the 2nd part of your question, once you have created capsules for all your known failures. You can use Seeq Formula to create a condition of "non-failures" with the Formula: $failure.growEnd(2yr) From there, you can use the TimeSince function in Formula to create a time counter between failures. TimeSince($nonfailures, 1d) Hope that completes the picture for you! -Chris O
  7. Hello Felix, Thorsten, If you know the start and end date of a particular event/failure, you can simply create a Custom Condition or accomplish the same result through Formula. Alternatively, you can use the CSV Import Tool to import multiple capsules if you have the start/end dates listed in a CSV file. Does this address your question, Felix? Chris O
  8. During a complex analysis, your Workbench can become cluttered with intermediate Signals and Conditions. Users utilize the Journal tab to keep their calculations documented and organized, often in the form of a Data Tray. If you have been adding Item links one-by-one, try using this trick to add all (or a large subset) of your items to your Journal all at once: Select all items in your display Click the Annotate button on the Toolbar Cut the Item links from your Annotation Paste the links into your Journal
  9. Sam, Thorsten, You cannot change or reduce the minimum required free disk space; however, changing the Seeq data folder to the D:// drive should resolve the issue you are seeing Sam. Doing so is the recommended approach in this scenario. Let us know if you have any additional questions. Best, Chris O
  10. Hey Paul, That is a great Feature Request. I've logged it internally as a development item and linked it to your organization. -Chris O
  11. AiKju, Here is screenshot of a mocked up example of what I understand you are looking for. Since your curve takes place in the time frame of 1 day, you can create daily capsules using Periodic Condition, then use Custom Condition to pick out the day you are interested in repeating (looks like January 1st, 2000). Use the following inputs in the Reference Profile to get the result your looking for: green curve as your Input Signal January 1st, 2000 condition as the Input Condition Set the Reference Statistic to Average Under Advanced, change the apply to Condition to your Periodic Condition of days created above. Once you execute, you should see a similar signal to my orange one below. The result should be the same as using Ben's approach. Don't hesitate if you have further questions.
  12. Great question! Yes - Seeq is able to create a new signal that represents the running hours/days of your piece of equipment. Signal from Condition is a great start as you've already found. To get what you are looking for, you'll need to use Seeq's Formula tool. I have mocked up a like-example below for your reference. In the first two lines of our Formula, we create hour long capsules with the hours() function, then transform those capsules to samples by counting the number of capsules that occur every hour, and give each sample a timestamp at the start of the hour using the .getstart() function. "hours().transformtosamples( $capsule -> sample($capsule.getstart(), hours().count($capsule)))" The 3rd line of our formula, ".runningsum($on).setunits('hr')" keeps a running sum of hours contained within your "ON" condition, then sets the appropriate units. In your example, this would be your purple "Pump is running" condition. As you can see in the display pane, our new signal resets for each new 'Compressor On' capsule. I hope this is what you were looking for. Please let us know if you have any additional questions. -Chris
  13. A new feature will be available in R21 to do just that. A "Dimming" icon will be available at the top of the display pane as a quick tool to toggle signals that are view-able so stay tuned. A few other potential workarounds for now: 1) Put the 8 unwanted signals in 1 lane, and the two desired signals in another. This will clean-up your view but will still only allow utilization of half of your display pane. 2) Put all 10 signals in one lane, then select only the two signals you'd like to view to make the other 8 less visible. You also may need to uncheck the 'Show' column within Customize to remove the y-axis for all unwanted signals. 3) Scatter Plot View will also allow you to compare just two signals while keeping all 10 in the worksheet.
