How to show the mapped field when using map

[aohls]

I am attempting to use the map command and table the data. I am trying to map in values to run through the a predict function and table the results. I get 90% there except the fields that are predicted do not populate the op value.

<my search>
| table op
|map [search op=$op$ <more search stuff> ]
...
| timechart count as Vol, values(op) as op
| predict Vol

When doing this I get a table with multiple times, once for each op like the below:

_time	Vol	op	high(prediction(Vol))	low(prediction(Vol))
12:00	10	test1	12	7
12:00	11	test2	14	8
12:15	15	test1	17	11
12:15	12	test2	15	10
12:30(predicted time)			16	10
12:30(predicted time)			12	9

Any ideas why this is no populating?

Try

| timechart count as Vol by op

This errors out, predict can't be used if the timechart has a split by.  I have used map work around this and pass in the op, run the predict for each oue and get the data. With the output though there is no way to tell what belongs to what op.
