I referred the above link but cannot understand how to build a visualization in Kibana for daily unique new users (that we have never seen before.
The following is a simplified look at our mappings in Elastic search
{
"mappings" : {
"properties": {
"userid": { "type": "keyword" },
"yyyy_mm_dd": { "type": "date", "format": "yyyy-MM-dd" },
"ts": { "type": "date"}
}
}
