title: Is it possible to create an XY (aka scatter) plot using Kibana 4?
body: <p>I have a few million documents in an ElasticSearch index with some numeric fields, say <code>foo</code> and <code>bar</code>. Is there any way to use Kibana 4 to create a graph with <code>foo</code> values on the X axis and <code>bar</code> values on the Y axis? Like a very, very basic chart one might create using Excel.</p>
  
  <p>I'm fine with sampling/aggregations of some kind. I understand that these tools won't show me a plot with 20 million data points. I'm just trying to see if there's some obvious relationship between <code>foo</code> and <code>bar</code> by creating a graph. </p>
