Question

Scheduled Sliding Window Integration

Hello,

I have a user who is interested in seeing a rolling total of a value within our Cognite instance. We have created a chart where we have a very simple setup of the data point we are interested in seeing over time, and a 30 day sliding window integration function on it, which is working fine and showing the value within the chart as needed. However, we are also interested in writing this data to another time series and then being able to display the current value of this time series on a canvas using the Live data point mode. I saved & scheduled the calculation to run daily within the Chart but the scheduled calculation and the time series which it created is getting no data, with no errors anywhere that I can see. Is this something that is possible to compute within Charts?

    It looks like there was a similar question early last year with an indication that an update around this would be completed in Q3 2025, is this still accurate or are there any further updates on timeline around this?

      Hi Quinn,

      What you are describing should be achievable in Charts. The pattern is a scheduled calculation that writes its output to a new time series, which you can then display in Canvas using Live mode. A plain calculation is computed on the fly in the chart and is not persisted, so scheduling it is the right move to get a reusable time series.

      On the output showing no data, a few things to check first:

      • Scheduled calculations only compute going forward from when you set them up. There is no backfill, and a daily schedule writes one point per run, so it can look empty until the first run has completed.
      • Make sure the calculation runs on a CDF client ID and secret rather than personal sign in. Scheduled calculations on personal credentials can stop when the session expires.
      • Confirm you are looking at the correct output time series over a time range that covers the runs.

      If it is still empty after a run has completed, reply with your schedule cadence and when you set it up, and I will help dig in.

      One clarification on the thread you linked: that request was about choosing the exact start time an hourly schedule fires. A rolling total does not depend on that, so it should not block what you are trying to do. I do not have a firm date to share on that specific enhancement, but we have noted the interest.

        ​@danielferraz Thanks for the info, I wasn’t aware of the restriction on personal credentials stopping when the session expires so that was likely my issue. I’ve re-created my schedule for this with a CDF Client ID & Secret to handle that just now. Is there a way to tell when a first run will happen for these schedules? I did once again set it up to run daily so does this mean it will just run each day overnight?

         

        I’ll respond back here again after I see some data coming through from a run.
