Infinite extent for field "<field name>" : [Infinity, -Infinity]

[Kamil_BdBelfort (Kamil Beeli de Belfort)]

Hi there,

I am using elasticsearch & kibana version 8.5.3

This is how my data look like when I run my script:

And here is my script:

  data: {
    url: {
      name: table
      index: insights_default_xod
      body: {
        size: 30
        _source: ["description", "metadata.properties.StartDate", "metadata.properties.EndDate", "metadata.properties.Project"]
        "query": {
          "bool": {
            "must": {
              "bool": {
                "filter" : {
                  "exists": { 
                    "field" : "metadata.properties.StartDate",
                    "field" : "metadata.properties.EndDate" 
                  }
                }
              }
            }
            "filter" : {
              "term": { "description" : "project" }
            }
          }
        }
      }
    }
    format: {property: "hits.hits"}
  }

  mark: bar

  encoding: {
    x: {field: "metadata.properties.Project", type: "nominal"}
    y: {field: "metadata.properties.StartDate", type: "temporal"}
    y2: {field: "metadata.properties.EndDate", type: "temporal"}
  }
}

When I click on update, I don't see any chart, instead I see the following warnings:

Can anyone tell me, how can I visualize my data?
I am trying to create Gantt Chart.

With regards,

Hi Kamil,

There is a similar discuss thread on generating using a Gantt chart that may help. It is using version 7 but the approach should be similar. Not sure if you are following that example?

[Marco_Liberati]

@Kamil_BdBelfort

in the encoding block, you need to access the _source property of your values to get the field data:

"encoding": {
    "x": {
      "field": "_source['metadata.properties.Project']",
      "type": "nominal"
    },
    "y": {
      "field": "_source['metadata.properties.StartDate']",
      "type": "temporal"
    },
    "y2": {
      "field": "_source['metadata.properties.EndDate']",
      "type": "temporal"
    }
  },

should work

Yes, this worked perfectly! Thank you @Marco_Liberati !

[Kamil_BdBelfort (Kamil Beeli de Belfort)]

Hi @carly.richmond ! I tried to follow this thread indeed without success.
Thank you for your reply

[carly.richmond]

No worries. Thankfully @Marco_Liberati came to the rescue. Glad it's all working now!
