  1. Hi Mattheus, You can do this by using the move (v49+) or delay (<=v48) function. For example, your equation would be: ($signal.move(5s)+$signal.move(10s)+$signal.move(60s))/3
  2. Hi Devin, In version R50, there are some additional features for Scatter Plot coming out including adding labels to the scatter plot that will show the values and timestamp next to it:
  3. Hi Sivaji, Sorry for another "you probably need to upgrade" response to your question, but if you look through the Knowledge Base on Scatter Plot (https://seeq.atlassian.net/wiki/spaces/KB/pages/153518135/Scatter+Plot), you'll see that a lot of these capabilities have been added. For example, starting in version 46, you can color by fixed date ranges, allowing more coloring options by time as you mention. The workaround on your version I believe would be to make each year its own condition using Custom Condition or something like that (one condition would be only the year of 2019, another condition being 2020 for instance). In this case, when you color by condition, it would be a different color for each condition.
  4. Hi Sivaji, This is not possible in version 45, but is available starting in version 48: https://seeq.atlassian.net/wiki/spaces/KB/pages/736035141/What+s+New+in+R22.0.48
  5. Hi Aleksander, The totalize function requires the totalization to be bounded by a capsule because otherwise it has no idea how far back in history to go. For instance, if you want to view the most recent day worth of data, does it have to go back through the entire history of your data signal (maybe 10+ years worth of data) to perform the calculation on? Therefore, the condition you give it will "bound" that calculation to a certain period of time so that Seeq knows when to start and stop that calculation. If I'm understanding correctly, I think you would want to "bound" the calculation each day to match the other sensor readout and I also think you would want the integral function instead of totalized so you get the running integral across the day. If so, first create a periodic condition for "daily" and then do: $signal.integral($DailyCondition) This will integrate the signal, resetting the integration each day. If you would like it to go longer, then change your condition as appropriate.
  6. You can only set the priority color based on conditions so you would need to create a condition off the signal. For example, you may do a Value Search to find when a capsule longer than a certain time length is found. In this case, you will first need to perform the totalized or summation using Signal from Condition and then you can do a Value Search on that signal.
  7. Hi Sivaji, You could do this in a couple different ways by turning the duration of the condition into a signal. One method would be to use Signal from Condition to calculate the duration of each capsule in the condition and then performing a sum on that signal for the Treemap statistic: Since you have to place the duration at a timestamp of each capsule, it means that if the "end" timestamp were selected as in the above example, the whole capsule would be counted even though half of the capsule may be off the edge of the time selected in the display. If this is an issue, I would recommend following the second approach. The second approach is to create a time counter signal using a Formula such as: 1.tosignal().within($condition) You can then totalize that signal to get the total number of seconds: If you want the value in a unit other than seconds, you can modify the example to use "sum" and a slightly different Formula that adds the units in. For example, in minutes:
  8. You should have an option at the bottom that allows you to select files from the local machine to attach to the forum that looks like this:
  9. Hi poeu, Here's one method for doing what you want: $max = $signal.aggregate(maxValue(),$condition,maxKey()).todiscrete() $start = $signal.aggregate(startValue(),$condition,maxKey()).todiscrete() $time = timesince($condition, 1min) ($max-$start)/$time In this formula, I'm first calculating the maximum value within the condition and storing that at the timestamp where the maximum was found. I then take the start value an also put that at the max key. Finally, I use timesince to get the calculated time (you can change the units depending on how long your capsule is) at that max timestamp. Note that your condition will need to have a maximum duration so you may need to add a $condition.removelongerthan(40h) or equivalent prior to the above formulas if your condition does not already have a max duration.
  10. Hi Isaac, While it's technically the same steps, you could do this all in one Formula with: $signal > 0 and $signal.derivative() == 0 Note that in versions below 49, you will replace "and" with "&&" in the above formula.
  11. Capsules can have properties or information attached to the event. By default, all capsules contain information on time context such as the capsule’s start time, end time, and duration. However, one can assign additional capsule properties based on other signals’ values during the capsules. This guide will walk through some common formulas that can be used to assign capsule properties and work with those properties. Note: The formula syntax used in the following examples will all be based on the formula language for Seeq version 49. If you have questions about errors you may be receiving in the formulas on different versions, please check out the What’s New in Seeq Knowledge Base pages for formula changes or drop a comment below with the error message. How can I visualize capsule properties? Capsule Properties can be added to the Capsules Pane in the bottom right hand corner of Seeq Workbench with the black grid icon. Any capsule properties beyond start, end, duration, and similarity that are created with the formulas that follow or come in automatically through the datasource connection can be found by clicking the “Add Column” option and selecting the desired property in the modal to get a tabular view of the properties for each capsule as shown below. In Trend View, you can Capsule Property labels inside the capsules by selecting the property from the labels modal. Note that only Capsule Properties added to the Capsule Pane in the bottom right corner will be available in the labels modal. In Capsule Time, the signals can be colored by Capsule Properties by turning on the coloring to rainbow or gradient. The selection for which property is performing the coloring is done by sorting by the capsule property in the Capsule Pane in the bottom right corner. Therefore, if Batch ID is sorted by as selected below, the legend shown on the chart will show the Batch ID values. When working with Scorecard Metrics, you can use a Capsule Property as the header of a condition based scorecard by typing in the property name into the header modal: How do I create a capsule for every (unique) value of a signal? Let’s say you have a signal that you want to turn into individual capsules for each value or unique value of the signal. This is often used for string signals (e.g. batch IDs, operations, or phases) that may look like the signal below. There’s two main operators that can be used for this: $signal.toCapsules() The toCapsules operator will create a capsule for each data point of the signal. Therefore, if there was only 1 data point per value in the string signal below, it would create one capsule per value, but if the string value was recorded every minute regardless of whether it change values, it would create 1 minute capsules. In addition, the toCapsules operator also automatically records a Capsule Property called ‘Value’ that contains the value of the signal data point. $signal.toCondition('Property Name') The toCondition operator will create a capsule for each change in value of the signal. Therefore, in the case above where the value was recorded every minute regardless of value changes, it would only create one capsule for the entire time the value was equivalent. Similarly to the toCapsules operator, the toCondition operator also automatically records a Capsule Property called ‘Value’ that contains the value of the signal data point. However, with the toCondition operator, there’s an optional entry to store the property under a different name instead by specifying a property name in the parentheses in single quotes as shown in the example above. Note: Sometimes when working with string signals of phases or steps that are just numbered (e.g. Phase 1), if there is only one phase in the operation, you may end up wanting two Phase 1 capsules in a row (e.g. Operation 1 Phase 1 and Operation 2 Phase 1) whereas the toCondition method above will only create a single capsule. In this instance, it can be useful to concatenate the operation and phase signals together to find the unique combination of Operations and Phases. This can be done by using the following formula: ($operationsignal + ': ' + $phasesignal).toCondition('Property Name') How do I assign a capsule property? Option 1: Assigning a constant value to all capsules within a condition $condition.setProperty('Property Name', 'Property Value') Note that it is important to know whether you would like the property stored as a string or numeric value. If the desired property value is a string, make sure that the ‘Property Value’ is in single quotes to represent a string like the above formula. If the desired value is numeric, you should not use the single quotes. Option 2: Assigning a property based on another signal value during the capsule For these operations, you will have to use a transform operator to perform a particular set of operations per capsule to retrieve the desired property. For example, you may want the first value of a signal within a capsule or the average value of a signal during the capsule. Below are some examples of options you have and how you would set these values to capsule properties. The general format for this operation is listed below where we will define some different options to input for Property Scalar Value. $condition.transform($capsule -> $capsule.setProperty('Property Name', Property Scalar Value)) The following are options for what to input into Property Scalar Value in the formula above to obtain the desired property values: First value of signal within a capsule: $signal.toScalars($capsule).first() Last value of signal within a capsule: $signal.toScalars($capsule).last() Average value of signal within a capsule: $signal.average($capsule) Maximum value of signal within a capsule: $signal.maxValue($capsule) Minimum value of signal within a capsule: $signal.minValue($capsule) Standard deviation of signal within a capsule: $signal.stdDev($capsule) Totalization of a signal within a capsule: $signal.totalized($capsule) Count the capsules of a separate condition within a capsule: $DifferentCondition.count($capsule) Duration of capsules in seconds of a separate condition within a capsule: $DifferentCondition.totalduration($capsule) There are more statistical operations that can be done if desired, but hopefully this gives you an idea of the syntax. Please leave a comment if you struggle with a particular operator that you are trying to perform. Finally, there are often times when you want to perform one of the above operations, but only within a subset of each capsule. For example, maybe for each batch, you want to store the max temperature during just a particular phase of the batch. In order to do this, first make sure you have created a condition for that phase of the batch and then you can use the following to input into Property Scalar Value in the formula above: $signal.within($PhaseCondition).maxValue($capsule) In this case, the within function is cutting the signal to only be present during the $PhaseCondition so that only that section of the signal is present when finding the maximum value. Option 3: Assign a property based on a parent or child condition In batch processing, there is often a parent/child relationship of conditions in an S88 (or ISA-88) tree hierarchy where the batch is made up of smaller operations, which is then made up of smaller phases. Some events databases may only set properties on particular capsules within that hierarchy, but you may want to move the properties to higher or lower levels of that hierarchy. This formula will allow you to assign the desired property to the condition without the property: $ConditionWithoutProperty.transform($capsule -> $capsule.setProperty('Current Property Name', $ConditionWithProperty.toGroup($capsule).first().property('Desired Property Name'))) Note that this same formula works whether the condition with the property is the parent or child in this relationship. I also want to point out that if there are multiple capsules of the $ConditionWithProperty within any capsule of the $ConditionWithoutProperty, that this formula is set up to take the property from the first capsule within that time span. If you would like a different capsule to be taken, you can switch the first() operator in the formula above to last() or pick(Number) where last will take the property from the last capsule in the time span and pick is used to specify a particular capsule to take the property from (e.g. 2nd capsule or 2nd to last capsule). There’s another write-up about this use case here for more details and some visuals: How do I filter a condition by capsule properties? Conditions are filtered by capsule properties using the keep operator. Some examples of this are listed below: Option 1: Keep exact match to property $condition.keep('Property Name', isEqualTo('Property Value')) Note that it is important to know whether the property is stored as a string or numeric value. If the property value is a string, make sure that the ‘Property Value’ is in single quotes to represent a string like the above formula. If the value is numeric, you should not use the single quotes. Option 2: Keep regular expression string match $condition.keep('Property Name', isMatch('B*')) $condition.keep('Property Name', isNotMatch('B*')) You can specify to keep either matches or not matches to partial string signals. In the above formulas, I’m specifying to either keep all capsules where the capsule property starts with a B or in the second equation, the ones that do not start with a B. If you need additional information on regular expressions, please see our Knowledge Base article here: https://seeq.atlassian.net/wiki/spaces/KB/pages/146637020/Regex+Searches Option 3: Other keep operators for numeric properties Using the same format of Option 1 above, you can replace the isEqualTo operator with any of the following operators for comparison functions on numeric properties: isGreaterThan isGreaterThanOrEqualTo isLessThan isLessThanOrEqualTo isBetween isNotBetween isNotEqualTo Option 4: Keep capsules where capsule property exists $condition.keep('Property Name', isValid()) In this case, any capsules that have a value for the property specified will be retained, but all capsules without a value for the specified property will be removed from the condition. How do I turn a capsule property into a signal? A capsule property can be turned into a signal by using the toSignal operator. The properties can be placed at either the start timestamp of the capsule (startKey) or the end timestamp of the capsule (endKey): $condition.toSignal('Property Name', startKey()) $condition.toSignal('Property Name', endKey()) This will create a discrete signal where the value is at the selected timestamp for each capsule in the condition. If you would like to turn the discrete signal into a continuous signal connecting the data points, you can do so by adding a toStep or toLinear operator at the end to either add step or linear interpolation to the signal. Inside the parentheses for the interpolation operators, you will need to add a maximum interpolation time that represent the maximum time distance between points that you would want to interpolate. For example, a desired linear interpolation of capsules may look like the following equation: $condition.toSignal('Property Name', startKey()).toLinear(40h) It should be noted that some properties that are numeric may be stored as string properties instead of numeric, particularly if the capsules are a direct connection to a datasource. In this case, a .toNumber() operator may need to be added after the toSignal, but before the interpolation operator. Finally, it is often useful to have the property across the entire duration of the capsule if there are no overlapping capsules (e.g. when looking at batches on a particular unit). This is done by turning the signal into a step signal and then filtering the data to only when it is within a capsule: $condition.toSignal('Property Name', startKey()).toStep(40h).within($condition) What capsule adjustment/combination formulas retain capsule properties? When adjusting or combining conditions, the rule of thumb is that operators that have a 1 to 1 relationship between input capsule and output capsule will retain capsule properties, but when there are multiple capsules that are required as the input to the formula operator, the capsule properties are not retained. For example, moving a capsule by 1 hour has knowledge of the input properties whereas merging 2 capsules together results in not knowing which capsule to keep the properties from. A full list of these operators and their stance on whether they retain or lose capsule properties during usage is below. Operators that retain properties Operators that lose properties afterEnd inverse afterStart merge beforeEnd fragment beforeStart intersect ends join starts union (if more than one capsule overlap) middles grow growEnd shrink move combineWith encloses inside subtract matchesWith touches union (when no capsules overlap) It is important to note that capsule properties are attached to the individual capsule. Therefore, using a combination formula like combinewith where multiple conditions are combined may result in empty values in your Capsule Pane table if each of the conditions being combined has different capsule properties. How do I rename capsule properties? Properties can be swapped to new names by using the renameProperty operator: $condition.renameProperty('Current Property Name', 'New Property Name') A complex example of using capsule properties: What if you had upstream and downstream processes where the Batch ID (or other property) could link the data between an upstream and downstream capsule that do not touch and are not in a specific order? In this case, you would want to be able to search a particular range of time for a matching property value and to transfer another property between the capsules. This can be explained with the following equation: $UpstreamCondition.move(0,7d) .transform($capsule ->{ $matchingDownstreamProperty = ($DownstreamCondition.toSignal('Downstream Property to Match Name') == $capsule.property('Upstream Property to Match Name')) $firstMatchKey = $matchingDownstreamProperty.togroup($capsule,CAPSULEBOUNDARY.INTERSECT).first().startkey() $capsule.setProperty('Desired Property Name',$DownstreamCondition.toSignal('Desired Downstream Property Name').tostep(40h).valueAt($firstMatchKey)) }) .move(0,-7d) Let's walk through what this is doing step by step. First, it's important to start with the condition that you want to add the property to, in this case the upstream condition. Then we move the condition by a certain amount to be able to find the matching capsule value. In this case, we are moving just the end of each capsule 7 days into the future to search for a matching property value and then at the end of the formula, we move the end of the capsule back 7 days to return the capsule to its original state. After moving the capsules, we start the transform. Inside the transform, we find the matching downstream property by turning the capsule property to match from the downstream condition into a signal and match it to the capsule property from the upstream capsule. We then find the key (timestamp) of the first match of the property. Again, similar to some other things, the first option could be swapped out with last or pick to grab a different matching capsule property. Finally, we set the property on the upstream condition to 'Desired Property Name' by turning the downstream capsule property that we want into a step signal and take the value where the first match was found.
  12. Hi kward, You can perform calculations across time by using the delay operator in Formula (or if you are on version 49+, the move operator). For example, if I wanted to calculate the current value minus 4 years ago, you can do the following Formula: $signal-$signal.delay(4y) This is essentially saying take my signal and subtract it from the same signal, just moved forward 4 years in time. By doing this, you align the current time and the time exactly 4 years ago to the same timestamp so that it can be subtracted. Note: Again, just for any people on version 49+, the .delay() operator would be switched to .move(). Note that this will do the calculation for every point in time. If you would like to do this based on daily, weekly, or monthly averages, then you should use Signal from Condition to calculate the average you'd like and use that as the $signal input into the Formula above.
  13. Hi Dominic, In order to specify both start and end time, you have to specify the exact time rather than just the day as the day or year option creates both a start and end time (for example, '2019' created both a start of Jan 1, 2019 at 12:00 AM and an end of Jan 1, 2020 at 12:00 AM). Therefore, your function would need to be formatted like this: 20$.tosignal().splice(10$.tosignal(), condition(100d, capsule('2019-02-01T00:00Z','2019-05-12T00:00Z')))
  14. Hi Dominic, You can use the splice function in Formula to complete this request. I'm assuming your cost changes each year so you may want to splice in a different cost for each year. For example, you can use the following Formula to say take the current cost of $20 and splice in $10 cost for all of 2019 so that on January 1st, it steps up to the new cost: 20$.tosignal().splice(10$.tosignal(), condition(1y, capsule('2019'))) Let me also break this Formula down a bit so that you understand it better. In the first part, we are saying take a value of $20 (as a signal) as the default result, which means that anytime before or after 2019 (in this case), the value would equal $20. However, when the capsule is present in the condition in the splice condition is met (in this case it's a capsule for all of 2019), the $10 signal will be spliced instead of the $20 signal. I also want to note that the '1y' argument in the condition is the maximum duration. If you wanted to expand the capsule to be longer than 1 year, you would also need to edit that value. If you want to add additional years at the $10 value, you can simply add them as more capsules in the condition argument. For example, adding 2018: 20$.tosignal().splice(10$.tosignal(), condition(1y, capsule('2019'), capsule('2018'))) If you want to add different values instead (let's say $15 for 2018), you could use the following modification: 20$.tosignal().splice(10$.tosignal(), condition(1y, capsule('2019'))).splice(15$.tosignal(), condition(1y, capsule('2018')))
  15. Hi aeina, You probably have something that looks like this with regards to the capsules you have already found: In order to do what you want, you first need to make capsules representing the time period you want to aggregate across. You can do this using Periodic Condition. For example if I wanted to compare years (2018 vs. 2019), I would make a yearly capsule. If I wanted to compare month to month, I could create a monthly capsule: Once you have that made, you can then use Signal from Condition to calculate the Total Duration of the original capsules during the bounding condition of the Monthly or Yearly capsule you created: This will give you the view like this: Alternately, you could use Scorecard Metric to create a tabular view of the same data:
