Rollups on dashboards

    Hi all,
    I have a kWh data source from a modbus slave device polling every 15 minutes. This is a cumulative value. I have also set up a meta datapoint to log 15 minute values (I had to do this as a delta roll up wont work for 15 minutes if there is only one value logged every 15 mins). That all good.
    Now I have set up an SVG graphic and on it I want to display current total, last month, last 15 minute value, max 15min value,
    I can get the current total and the last 15 minute value no problem as they are last values received I but cant figure out how to do a rollup on the SVG graphic.
    Any suggestion? Thanks

    Rob

 <ma-get-point-value point-xid="15MinuteEnergyX" point="15MinuteEnergyPt"></ma-get-point-value>
 <ma-svg ng-include="'/modules/mangoUI/web/img/5Ecohousepanel.svg'" style="position: absolute; width: 900px; height: 480px; left: 920px; top: 0px;">

    Take a look at the ma-point-values item under the Api docs -> components. Also check the examples.
    You'll be able to see how to apply it to get the rollups you desire to display the figures you want.

    Hi @Robmalone

    You should also look at the document for <ma-point-statistics> it returns a statsObject which you can then use statsObject.last, statsObject.max etc. this would be a lot easier to use than <ma-point-values> you for purpose.
