Date Histogram on Bar chart does not update time interval in legend if scaling is forced

[robin13]

Kibana version: 4.6.1

In bar chart with a date histogram aggregation if the interval is set to "Second", but the interval would have created too many buckets and so the time range is scaled (e.g. to 5 Seconds) the legend below the chart wrongly says "per second":

On line chart the legend is displayed correctly.

Good catch!

The other problem is that it really isn't correct to show that interval on the x-axis like it is.
That x-axis is showing @timestamp values.
It's the Y-Axis that is showing something like Average sum of kwh per 5 seconds and not Sum of kwh.
We have the same issue on Discover histogram.

Without the proper labeling of the Y-Axis the scale can be very confusing.

Working as expected, the x-axis labels are scaled to match the units in the label

@jimgoodwin I disagree - look at the ticks on the screenshot: they are every hour, and the lable says that the bars should be "per second" but we know from the alert on the left side that they are "per 5 second" - if this visualisation was in a dashboard without the context of the left bar, it would be very misleading.

I think I noted this in another similar issue, but the X-Axis should just be @timestamp. The Y-Axis scale is really showing Sum of kwh/5 seconds and maybe should just say that.

I am closing it as I can't reproduce it in the latest minor
