Data Field: AppBuilder

Reposting a couple of updates that were lost in the forum migration:

Update 5.21 (5/5+)

Large memory devices: Add optional 3rd parameter to PREVD and PREVT which controls the number of samples to collect (previously fixed at 10).

e.g. PREVD(Timer, 5000, 5000) returns the time from 5000 metres ago, with a resolution of 1 metre (5000/5000)

e.g. Display the total time for your last 5k:

Notes: Large memory devices like Fenix 5+/5X can handle at least 5000 samples. 645 Music can handle 2000 samples.

Update 5.22 (5/5+):

Large memory devices: Add optional 4th parameter to PREVD and PREVT which prevents data from being reset on pause.

0: reset data on pause
1: don't reset data on pause
e.g. PREVD(Timer, 5000, 5000, 1)

As mentioned in the original thread, I would like to bring this feature to older devices (CIQ 2 devices, like 935, 645, and Fenix 5), but I'm a little worried about the slight memory hit. They certainly won't be able to handle anything close to 2000 samples. (100 or so would probably be the limit, although I haven't tested it.

with this update PREVD or PREVT can sostitute TIMEAVG for calculate average value on samples ?

It looks like Activity.Info.track is only available on devices that support "advanced" navigation. I tried VAHR, Vivoactive 3 and 645 (a mix of CIQ2/3 devices which all lack nav support) and they all produce the "!Name" error. I also tried a more direct test, with the same results (jic there was a problem with my code.)

I feel like this is a bug in the CIQ docs, which I will report shortly. I'll also have to fix my docs.

I could use Position.info.heading, but it adds a tiny amount of code which could break existing formulas (especially for CIQ1). I'll have to see if I can find a way to cut the fat somewhere.

Thanks for bringing that to my attention!

Update 5.23 (AppBuilder 5 only)

Add support for 245, 245 Music, 945, Edge 530, Edge 830, MARQ

hi

there is a formula with AppB5 to exclude peak of values?

for example, if i have these numbers:

45, 35, 30, 150, 37,400,5, 2

i want exclude high values and low values and calculate average values of others.

Calculate average value of only 45,35,30,37.

(SUM(X) - MIN(X) - MAX(X)) / (SUM(X neq null) - 2)

For the first two seconds, this will display nonsense. If you care about that, you can use a slightly longer version:

if (sum(x neq null) gt 2, (SUM(X) - MIN(X) - MAX(X)) / (SUM(X neq null) - 2), null)

I will point out that since X is evaluated every second, for any activity that lasts more than a few seconds, you won’t see much of a difference compared to AVG().

thanks FlowState

but (X) is a list of number ?

i need to analize for example last 5 samples using PREVN and calculate average value removing high and low peaks.

i understand the formula but not much (X)..
