Retrieve last 12 hours of data

The second form is probably the preferred form. In the preceding form, it will be updated every digest cycle regardless of what triggered that digest update (the default timer, some other modeled object, etc) while the latter will only update on the update interval, even if other things change in the digest.

Hi @phildunlap
Thanks!
Is ma-point-values the best way to get all this data to show on a chart? We are using ma-point-values to retrieve 12 hours of values for 12 or so points, and it really feels like it is slowing down the entire page significantly

How often are you retrieving point values? If you have a timer (ma-now) and are updating the query for point values too regularly you will definitely cause the system to bog down.

Jared, we are retrieving once per minute.
Am I correct in this assumption:
Calling ma-point-values fetches all 12 hours (for example) of data every single time you call it?
Or, does it only fetch the latest data?If the former, is there a better way of doing this? I can probably create an array and call ma-get-point to get the latest point and push to the array rather than getting 12 hours worth of data every minute for 8+ points.
Thanks!

Correct. Although saying "calling" is a little confusing, its not a function, its an Angular component. It will fetch all 12 hours when its attributes change (e.g. when the time period changes).

Are you talking about point values rather than points?
This is essentially what the
<ma-point-values>component does if you set thelatest="x"attribute.Are you sure that you don't have some other error in your console (e.g. infinite digest error) which could be causing the page to bog down?

Hi, yes no error.
How would we use latest if we wanted 12 hours worth of data (point values) for ma-serial-chart?
I thought about using
latestinitially but as there is only a way to limit the scope of latest via NUMBER of points rather than time-duration, I moved away from it.My end goal is to populate ma-serial-chart with 12 hours of point values for multiple datapoints. I can send you the code I am using to do that now if it would help.

You would have to know the sample/poll period of the data points.

What rollup are you using? Have you opened your chrome developer tools and checked the network requests that are going out? Check they aren't occurring more frequently than you intended and that they aren't taking too long to complete.
You can post up your code if you would like, sure.

Here's how I would accomplish what you are doing:
<ma-watch-list-get ng-model="designer.watchList" parameters="designer.parameters" on-points-change="designer.points = $points" id="d01a1ce8-d4d7-43b3-831c-9c619fb4bace" watch-list-xid="WL_ac76beaa-10f4-40f0-b714-d0fda1c1e801"></ma-watch-list-get> <div class="ma-designer-root" id="4a3435f4-e428-4ee2-8ba8-1cf4511aa999" style="width: 1366px; height: 768px; position: relative;"> <ma-point-values id="5a8730ae-18bc-443c-8bad-e9ef83ccf104" points="designer.points" rollup-interval="15 minutes" rollup="FIRST" to="designer.time" from="designer.time | maMoment:'subtract':12:'hours'" style="position: absolute; left: 27px; top: 0px;" values="designer.values"></ma-point-values> <ma-serial-chart id="2796c91b-75b7-4759-9228-60d2e840b90f" style="position: absolute; width: 854px; height: 541px; left: 29px; top: 93px;" points="designer.points" values="designer.values" legend="true"></ma-serial-chart> <ma-now id="2269ccdd-6d99-4732-81a4-3d607e73dbb8" style="position: absolute; left: 210px; top: 0px;" update-interval="1 minute" output="designer.time"></ma-now> </div> -
Here is what we are doing now -- I am not very familiar with Angular, my experience is largely with React -- can you advise if this is a bad way to do this?

@rshah two things
a) I would strongly suggest moving your page into a custom / dashboard designer page inside the UI module. I can tell you that the above page will break upon installation of Mango 3.4
To make the page full screen / no menu and toolbar, see here - https://forum.infiniteautomation.com/topic/3297/deploying-custom-page/3b) Don't get every point and its values individually. Use a watch list as I posted above. You can use multiple watch lists if you want multiple charts. This also lets you dynamically add/remove points from the watchlist and you wont have to change your page markup.

Thanks a lot!
We will do that.
