How to minipulate chart numbers?

[clintla]

The below chart works great

chart sum(free_contig) over source by RaidGroup_Type

I'd like my sum (in megabytes) to be converted to gigabytes
& I was trying stuff like

chart sum(free_contig)/1024 over source by RaidGroup_Type
chart (sum(free_contig)/1024) over source by RaidGroup_Type
chart eval(sum(free_contig)/1024) over source by RaidGroup_Type

Oddly cant find much on dividing in the splunk documentation and
none of my attempts have worked.

That worked well.. thank you!

I think this should work. Maybe you were just missing the rename operation (i.e. "... as free_config_GB"):

... | chart eval(sum(free_config) / 1024) as free_config_GB over source by RaidGroup_Type
