Encode time series data in a single field

[mvdobrinin]

Good day everyone. I am looking for a way to be able to send a single event that would include some timeseries data for the last few days.

{
    "service": "A",
    "series": <???>
}

Is there a way for Splunk to look at a single field/attribute and pull out time series data? For example something simple like -

6|
5|
4|                  x
3|         x
2|      x       x
1|  x
-------------------------
    t0  t1  t2  t3  t4

I am flexible on the client side and could encode the payload in whatever format is needed.
