Problem with changing statistical function of field chart

[bernd]

I generated a chart for a field in the search UI, changed the value to "total" and added the chart to a dashboard. The widget on the dashboard looks correct (same as in the search UI) and the database entry for it looks like this. ("valuetype": "total")

        {
            "creator_user_id" : "admin",
            "cache_time" : 10,
            "description" : "Field graph",
            "id" : "e70fbc12-efe3-4f9c-a859-c99856166ec3",
            "type" : "field_chart",
            "config" : {
                "valuetype" : "total",
                "timerange" : {
                    "type" : "relative",
                    "range" : 3600
                },
                "renderer" : "area",
                "interpolation" : "linear",
                "field" : "nf_bytes",
                "query" : "*",
                "interval" : "minute"
            }
        }

Then on the dashboard I changed the "Statistical function" of the widget to "Mean" and then back to "Total". Now the widget looks different and the database entry has count instead of total for the valuetype config option.

        {
            "creator_user_id" : "admin",
            "cache_time" : 10,
            "description" : "Field graph",
            "id" : "e70fbc12-efe3-4f9c-a859-c99856166ec3",
            "type" : "field_chart",
            "config" : {
                "valuetype" : "count",
                "timerange" : {
                    "type" : "relative",
                    "range" : 3600
                },
                "renderer" : "area",
                "interpolation" : "linear",
                "field" : "nf_bytes",
                "query" : "*",
                "interval" : "minute"
            }
        }

Is this a bug or just confusing naming of the statistical function? I expected to get the "valuetype": "total" back when I changed the statistical function back to "Total".

Apparently there is some mix up with the statistical values used in the statistical widgets and field charts, I can confirm this issue.
