Hi Team,

I'm trying to plot a line graph using vega-lite. How to give KQL formulas in vega-lite. I used field called "claculate" but may be my syntax is wrong. Please help on creating line graph.

```auto
{
  "$schema": "https://vega.github.io/schema/vega-lite/v5.json",
  "title": "Performance metrics",
  "data": {
    "url": {
      "%context%": true,
      "%timefield%": @timestamp,
      "index": "bkp-ispfw-15032023"
    }
  },
  "transform": [
    {
      "calculate": "count(kql='Status: \"TP\"')/(count(kql='ValidGTPoint:\"True\"'))", "as": "PDJ Score" 
    }
  ],
  "mark": {
    "type": "line",
    "point": true
  },
  "encoding": {
    "x": {"timeUnit": "year", "field": "date"},
    "y": {"aggregate":"mean", "field": "price", "type": "quantitative"},
    "color": {"field": "symbol", "type": "nominal"}
  }
}

```

Error its not showing which line and any other details. Just giving below error.  
`Unexpected token =`

Thanks in advance.

Hi @Nanditha

it looks like you are using a Lens formula within a Vega context: that is not possible as formula is a Lens specific feature.  
You have to manually create a query to retrieve 2 filtered counts, and then perform the Vega calculation on the fields.
