Time intervals for data aggregates

Hi all,

I have stored in my Influx instance a lot of very-high-frequency data.
I was wondering how to aggregate them, in order to visualize them fastly.
Using Chronograf, minimum time interval for grouping data is 1 second: what is the correct syntax for aggregate data, for example, each 0.1 seconds? Or half second? Or maybe 0.0001 seconds?

Try replacing

GROUP BY time(:interval:)


GROUP BY time(100ms)
