Vega Plugin: Use input signal in query

Elastic Stack Kibana
1

I have a vega visualization with an input signal (dropdown). I want to use this value to update the query to elastic and set the size parameter.

...
"signals": [
	{ "name": "points", "value": 10,
      "bind": {"input": "select", "options": [20,30,40,50]} },
	]
...
"data": [{
"name": "data",
"url": {
	"index": "testindex*",
	"body": {
		"size": {"signal": "points" }        # Here I want to use the input from the signal
	  }
    }
}]

How can I achieve this?

@keff this would be a very cool improvement, and it has already been asked for. I hope to get to it fairly soon. Please track https://github.com/elastic/kibana/issues/17211 to know when it gets done. Also, please check that ticket to see if it fully meets your goals. Thx!
