Goog Morning.

I need to create a Gannt chart using Kibana. I know the first way to do that is using the Visualization section, introducing a Vega code. I need to visualize these fields from an Elastic Search Index: RoboId, StartTime, EndTime. I'm trying using the following code, but I'm getting a message about:

" Infinite extent for field "starttime": [Infinity, -Infinity] "  
" Infinite extent for field "endtime": [Infinity, -Infinity] "

```auto
{
  $schema: https://vega.github.io/schema/vega-lite/v4.json
  title: Gannt
  data: {
    url: {
      %context%: true
      %timefield%: starttime
      index: cs_gannt
      body: { }
    }
    format: {
      property: hits.hits
    }
}
mark: bar
// At this point the search values are exposed from the _source object
  encoding: {
    y: {
      field: robotid
      type: ordinal
    }
    x: {
      field: starttime
      type: temporal
    }
    x2: {
      field: endtime
      type: temporal
    }
  }
}

```

Can someone help me to undestrand where i'm doing wrong, providing a correct code?

Thanks so much...

In general, the `Infinite extent for field` issue is because the path does not match one of the paths in your `data` array. You'll need to follow the [Vega debugging steps](https://www.elastic.co/guide/en/kibana/7.13/vega.html#vega-inspector) yourself, unless you [follow the steps for asking for help with a Vega spec](https://www.elastic.co/guide/en/kibana/7.13/vega.html#asking-for-help-with-a-vega-spec).

Also I would check your timefilter since you are using `%timefield%: starttime` and ensure there are results in that range.

In Vega, your `field` must match one of the paths in the JSON from your data.
