Histogram

[nikolhaas65]

Historgram is very common tool to visualize distributions. In provided examples with sales, it could be about comparing "sales" historgrams for different "cities". For realtime applications monitoring certain distributions is priceless.

PS. I just started using perspective, forgive me if histograms are implemented already. I just could not find them.
PSS. Quick self-reflection: perhaps, I can prepare histogram within DataFrame and then send it to Table/View

You can create a histogram by selecting an "X Bar" or "Y Bar" chart with your desired column in group_by field, and as (any) one column selected in the columns field with an aggregate of "count". You can combine this with an expression column with the bucket() function as well, as in this superstore View config:

{
    "plugin": "X Bar",
    "group_by": [
        "Sales Bucket"
    ],
    "columns": [
        "Sales"
    ],
    "expressions": {
        "Sales Bucket": "bucket(\"Sales\",100)"
    },
    "aggregates": {"Sales": "count"}
}
