Introducing new maxKey(), maxValue(), minKey() and minValue() functions

[Sanman Mehta]

Starting with Seeq R.21.0.44.0 release, user can specify maxValue() and maxKey() on a signal during a capsule to return the scalar values of maximum value and associated time stamp respectively.  The example below shows that on Temperature signal, during 16^th October (capsule), maxValue() function results in 106.07 ºF and maxKey() function results in associated timestamp 2019-10-16 02:18 am i.e. when maximum temperature occurred.  See the 1^st image for this example in Seeq:

Feel free to try out these formulas on your own:

$temperature.maxKey(capsule('2019-10-16T00:00Z','2019-10-17T00:00Z'))

$temperature.maxValue(capsule('2019-10-16T00:00Z','2019-10-17T00:00Z'))

Oh one more thing, you can also create signals that return one value from each capsule within a condition. Where value can be maxValue(), minValue(), maxKey(), minKey().

Below is one such example and an image showing that you can create signal that represents minimum values at minimum key (time) on daily basis:

$signal.aggregate(minValue(), $condition, minKey())

As always detailed information can be found in formula tool panel documentation search box in Seeq application.
