The ["line chart" demo](https://vega.github.io/vega-lite/examples/line.html) works fine, and is expressed in javascript, as in [getting\_started.html](https://vega.github.io/vega-lite/tutorials/getting_started.html).

... but **when I replace "data" field from URL to inline values**, it shows only the axys, no chart into. 

It works: `"data":{"url":"https://vega.github.io/vega-lite/examples/data/stocks.csv"},`

It **not** works:

```js
var vlSpec = {
  "$schema": "https://vega.github.io/schema/vega-lite/v4.json",
  "description": "Google's stock price over time.",
  "data":  {"values": [
      {"symbol":"MSFT","date":"Jan 1 2000","price":39.81},
      {"symbol":"MSFT","date":"Feb 1 2000","price":36.35},
      {"symbol":"MSFT","date":"Mar 1 2000","price":43.22},
      {"symbol":"MSFT","date":"Apr 1 2000","price":28.37},
      {"symbol":"MSFT","date":"May 1 2000","price":25.45}
  ]},
  "transform": [{"filter": "datum.symbol==='GOOG'"}],
  "mark": "line",
  "encoding": {
    "x": {"field": "date", "type": "temporal"},
    "y": {"field": "price", "type": "quantitative"}
  }
};

```

There are an error at console, that not make sense:

*WARN Infinite extent for field "date": [Infinity, -Infinity]*
