Visualization of date/time as metrics

[Mattias Bogeblad <ma...@gmail.com>]

Hi, I just started working with Superset and it's promising so far - good
job.

I do have one question which is kinda critical for us. We measure customer
wait times in stores and we want to present that in a visual graph and not
just in a table. For example I tried to show it in a time-series line graph
so one could see the waiting time during different periods of the day.

The problem I cannot get my head around is how I get the metric (the wait
time - a metric in seconds) shown in the y-axel of the diagram as a date
and not just as a number. I want the scale on the Y-axis to be
hours/minutes/seconds or similar so its readable. Have the customer waited
21 minutes I don't want y-axis to draw 1260 seconds but rather in a
time-format.

Is this possible in any graph type in any way? I can do mods in the backend
query if that helps.

Regards
Mattias
