I want make a simple diagram where I take data from index for 2 ordinal variables and using one of the ordinal variables as a key for x axis count the other ordinal variable on y axis and show it as a histogram.

this is what I did -

{  
$schema: "[https://vega.github.io/schema/vega/v3.0.json](https://vega.github.io/schema/vega/v3.0.json)"  
"title": "Event counts from all indexes"  
"data": {  
"url": {  
"index": "apm\*",  
"body": {  
"query" : {  
"range" : { "@timestamp" : {"%timefilter%" : true }}  
},  
size : 1000  
\_source: ["@timestamp","lables.application", "lables.platform", "lables.correlation\_id", "lables.is\_error", "process.pid"]  
}  
}

```
format: {property: "hits.hits"}

```

}  
"mark" : "bar"  
"encoding": {  
"x" : {  
"field" : "datum.\_source['lables.application']", "type" : "nominal"  
},  
"y" : {  
"field" : "datum.\_source['lables.platform'], "type" : "nominal"  
}  
}  
}  
}

Make sure you have corrected any typos. You have `lables` and `colour` which I don't believe are recognized.
