How do you subtract values from an appended search?

I'm trying to run the below searches and get the subtracted value from them. However, the eval command is not giving me a new Difference field. I just get the results of the separate searches.

index=a sourcetype=test start=* end=* | eventstats count as Total1
| append [search index=a sourcetype=test start=* end=* xfer=* | eventstats count as Total2]
| eval Difference=Total1 - Total2

I'd like a chart that with a row for all three values.

Total1        Total2          Difference
10               8                   2

Hello @jephillips ,

Try this:

index=a sourcetype=test start= end= | stats count as Total1
| appendcols [search index=a sourcetype=test start= end= xfer=* | stats count as Total2]
| eval Difference=Total1 - Total2

You can try the below search-

index=a sourcetype=test start= end= | stats count as Total1
| appendcols [search index=a sourcetype=test start= end= xfer=* | stats count as Total2]
| eval Difference=Total1 - Total2
