Hello, i've been trying to create a grouped bar chart in kibana with vega lite, as shown in this [example](https://vega.github.io/vega-lite/examples/bar_grouped_repeated.html), but i always get a warning "xOffset-encoding is dropped as xOffset is not a valid encoding channel". As a result, i don't get to group the bars. ![vega-lite-warn](https://us1.discourse-cdn.com/elastic/original/3X/d/e/de023a262e1aa2c790bb6413f047bebe5e247f3e.png) The exemple works fine in the vega editor so i'm wondering if this could be a Kibana issue or if there's there's something i am missing. I share my spec. ```auto { "$schema": "https://vega.github.io/schema/vega-lite/v5.json", "title": "Test", "data": { "format": { "property": "aggregations.users_per_day.buckets" }, "url": { "index": "test-*", "body": { "size": 0, "aggs": { "users_per_day": { "date_histogram": { "field": "@timestamp", "calendar_interval": "day", "extended_bounds": { "min": 1637539200000, "max": 1638144000000 }, "min_doc_count": 0 }, "aggs": { "distinct_users": { "cardinality": { "field": "identifier" } }, "total_new_users": { "cumulative_cardinality": { "buckets_path": "distinct_users" } }, "incremental_new_users": { "derivative": { "buckets_path": "total_new_users" } } } } }, "query": { "bool": { "must": [ { "range": { "@timestamp": { "gte": "2021-11-22T00:00:00.000Z", "lte": "2021-11-29T00:00:00.000Z", "format": "strict_date_optional_time" } } } ], "filter": [], "should": [], "must_not": [] } } } }, "values": { "took": 5, "timed_out": false, "_shards": { "total": 56, "successful": 56, "skipped": 49, "failed": 0 }, "hits": { "total": 170, "max_score": null, "hits": [] }, "aggregations": { "users_per_day": { "buckets": [ { "key_as_string": "2021-11-22T00:00:00.000Z", "key": 1637539200000, "doc_count": 5, "distinct_users": { "value": 3 }, "total_new_users": { "value": 3 } }, { "key_as_string": "2021-11-23T00:00:00.000Z", "key": 1637625600000, "doc_count": 17, "distinct_users": { "value": 1 }, "total_new_users": { "value": 3 }, "incremental_new_users": { "value": 0 } }, { "key_as_string": "2021-11-24T00:00:00.000Z", "key": 1637712000000, "doc_count": 32, "distinct_users": { "value": 2 }, "total_new_users": { "value": 3 }, "incremental_new_users": { "value": 0 } }, { "key_as_string": "2021-11-25T00:00:00.000Z", "key": 1637798400000, "doc_count": 31, "distinct_users": { "value": 2 }, "total_new_users": { "value": 3 }, "incremental_new_users": { "value": 0 } }, { "key_as_string": "2021-11-26T00:00:00.000Z", "key": 1637884800000, "doc_count": 40, "distinct_users": { "value": 5 }, "total_new_users": { "value": 6 }, "incremental_new_users": { "value": 3 } }, { "key_as_string": "2021-11-27T00:00:00.000Z", "key": 1637971200000, "doc_count": 30, "distinct_users": { "value": 2 }, "total_new_users": { "value": 6 }, "incremental_new_users": { "value": 0 } }, { "key_as_string": "2021-11-28T00:00:00.000Z", "key": 1638057600000, "doc_count": 15, "distinct_users": { "value": 2 }, "total_new_users": { "value": 6 }, "incremental_new_users": { "value": 0 } }, { "key_as_string": "2021-11-29T00:00:00.000Z", "key": 1638144000000, "doc_count": 0, "distinct_users": { "value": 0 }, "total_new_users": { "value": 6 }, "incremental_new_users": { "value": null } } ] } } } }, "repeat": { "layer": [ "distinct_users.value", "total_new_users.value", "incremental_new_users.value" ] }, "spec": { "mark": "bar", "encoding": { "x": { "field": "key", "type": "nominal", "timeUnit": "monthdate", "axis": { "title": "Date" } }, "y": { "field": { "repeat": "layer" }, "type": "quantitative", "axis": { "title": "Number of users" } }, "color": { "datum": { "repeat": "layer" }, "type": "nominal" }, "xOffset": { "datum": { "repeat": "layer" } } } }, "config": { "range": { "category": { "scheme": "elastic" } }, "mark": { "color": "#54B399" }, "title": { "color": "#343741" }, "style": { "guide-label": { "fill": "#69707d" }, "guide-title": { "fill": "#343741" }, "group-title": { "fill": "#343741" }, "group-subtitle": { "fill": "#343741" } }, "axis": { "tickColor": "#eef0f3", "domainColor": "#eef0f3", "gridColor": "#eef0f3" }, "background": "transparent" }, "width": "container", "height": "container", "autosize": { "type": "fit", "contains": "padding" } } ``` ---
