Remove spaces in field values and run stats/timechart with new names

[smhsplunk]

I notice Splunk uses the first Word when using stats, so I need to rename the fields to single words or connected words.

I am trying to remove spaces in field names and use the new name to be used in drop-downs and timecharts. Till now, I've been unable to perform this. Following is a drop-down menu where
I only want unique City Names. I would also want to use the new names in stats.

       source=location sourcetype=location_data
                  | search * "Current City" 
          | dedup "Current City"  
                  | sort "Current City"                   
          | rename "Current City" as City 
                  | rename "Current State" as State 
                  | rename "Current Location" as Location
                  | fields City

OK, so the problem is not that your field name has spaces but rather that your field value does. So you do not need rename, you need something else. Try using this (early in your command chain):

... | rex field="Current City" mode=sed "s/ /_/g"

Excellent this works, is it possible to do the same thing without removing spaces ? Keeping column values as it is ?

Yes, you can protect your values by surrounding the field name references with double-quotes or dollar-signs. It all depends on your actual XML and search.
