Hey everyone.
EDIT: I'm using Kibana 7.11
I'm eventually trying to create one of these diagrams using Vega-Lite:
It looks easy enough but I'm trying to use pre-aggregated data so I'm starting by just trying to get the histogram to appear.
Here is my Vega Spec:
{
"$schema": "https://vega.github.io/schema/vega-lite/v4.json",
"title": "Event counts from all indexes",

},

},

},
{
"key": 2000000000,
"doc_count": 2979
},
{

}
}
}
},

Here is my Vega-Lite visualization:
{
$schema: https://vega.github.io/schema/vega-lite/v4.json
title: Event counts from a single index
data: {
url: {
%context%: true
%timefield%: @timestamp
index: kpis
body: {
aggs: {
2: {
histogram: {
field: duration
interval: 1000000000
min_doc_count: 0
}
}
}
size: 0
}
format: {
property: aggregations.2.buckets
}
}
}
transform: [{
flatten: ["aggregations.2.buckets"]
as: ["buckets"]
}]
mark: bar
encoding: {
x: {
field: key
bin: true
type: nominal
}
y: {
field: doc_count
type: quantitative
axis: {
title: Document count
}
}
}
}
I'm getting an error message like this:
* Infinite extent for field "key": [Infinity, -Infinity]
* Infinite extent for field "doc_count": [Infinity, -Infinity]
But I have no idea what I'm doing wrong...
Anyone got any ideas?
Thanks in advance.
