Canvas JS data sampling in php

[fasi]

How to plot the difference between two points along with the date-time range as shown in the below link?

foreach ($model as $row)
   {
    // pushing for kwh values
    array_push($dataPointskWh, array("label"=>$row['Data_Date_Time'],"y"=>$row['kWh']));
   }

@fasi,

Can you kindly create a sample project reproducing the issue and share it with us over Google-Drive or Onedrive along with the sample data/database so that we can look into the code, run it locally to understand the scenario better and help you resolve?
