Any similarity to your issue?

In all of the example-DATABASES you will find Tag-Fields.
Tag-Fields includes several values.

You can generate an object out of your array, like this one…

myData=[
  {
    "_id": "0",
    "engineTime": "1000",
    "engineCycle": "800",
  },
  {
     "_id": "1",
    "engineTime": "1001",
    "engineCycle": "801",
  },
  {
     "_id": "2",
    "engineTime": "1002",
    "engineCycle": "802",
  }
]

…and push it to a table or a repeater…

$w("#myRepeater").data= myData;
