  • Hi All,

    I've asked a similar question before but we're still having some trouble understanding the best way to create a serial chart for the past 12 hours.

    What we are doing now works BUT, if you graph "too many" points (one of our dashboard pages has 7 points across two graphs), the page loads very slow and crashes frequently. I believe the way we are doing it now is not the best way, so I'm hoping for some advice.

    Is there a more efficient way to achieve what we want?

    This is a small sample of what we are doing now:

    <!-- We only want to obtain last 12 hours of data, so use Angular Moment Library to do figure out what last 12 hours are-->
    <ma-now update-interval="1 minutes" output="to"></ma-now>
    <ma-calc input="to | maMoment:'subtract':12:'hours'" output="from"></ma-calc>
    <!-- Get last 12 hour of flow, suction, and output pressure data, averaged over 1 minute -->
        rollup-interval="1 minutes">

    Here's the dasboard:

    Some further info:


  • Your code looks good to me.

    @rshah said in Difficulty Graphing for custom date / time range:

    the page loads very slow

    How slow is "very slow"? What else is on the page? Are you using the Mango TSDB?

    crashes frequently.

    I'm guessing if you run the profiler for more than a minute you will see a spike in activity every minute, how long does it take to stabilize? Maybe take a longer profile, save it and send it to me (PM me a dropbox/google drive etc link).

    I guess slow is relative to our other pages, this one is about 4second load time vs the rest which are <1s

    Nothing else on the page except what is in the screenshot above

    Not sure what Mango TSDB is

    Link PMd, thanks!


  • The Mango TSDB also know as the Mango NoSQL Database is our Time Series Database that comes with our commercial installations. You can check under Administration > Modules and look for it there. 0_1532038699380_ed280982-fbdf-4652-ab29-658a2f8ef4ec-image.png

  • Looks like we are using it:


  • Hi @Jared-Wiltshire

    Just want to confirm you rec'd the PM with the chrome profiler?



  • @rshah Yes, sorry busy week.

  • No problem!

    Here's another screenshot which might give you some ideas as well -- left the dashboard open on my PC overnight and it crashed -- it crashes much faster on our display PCs, but they do have fairly good specs.
