hi,  
I want to present the plots for documents with "group"==a, and I only want to present documents with the latest date of the time range applied by the dashboard.  
How can I do this?  
here is my script:

```auto
{
  $schema: https://vega.github.io/schema/vega-lite/v2.json

  data: {
    data: table
    url: {
      %context%: true
      %timefield%: Time
      index: data*
      body: {
        size: 10000
        _source: ["X", "Y","group"]
      }
    }
    format: {property: "hits.hits"}
  }
  mark: {type: "square", filled: true, size: 800 }
encoding: {
    x: {
      field: "_source.X"
      type: quantitative
      axis: {title: "X"}
    }
    y: {
      field: "_source.Y"
      type: quantitative
      axis: {title: "Y"}
    }  
}
}

```

the `%context%: true` and `%timefield%: Time` part defines that the ES query used, will be augmented with the filters and query applied to the query bar and the time range used.  
If you for example type a search on the query bar like: `group : "A"` this will filter out all documents with that specific `group` value also on your vega visualization.  
If you need the top X values sorted by the latest date, you can apply a sort operation on the vega ES query on the timefield, something like `"sort" : [{ "@timestamp" : {"order" : "desc"}}],`
