Condensed multi-series chart

[jenkinsta]

I have a speedtest from ookla that runs every 30 min and returns results from 3 servers.

Here is my search:

sourcetype="SpeedTest" 
| convert num(download.bandwidth) as D_bnd
| convert num(upload.bandwidth) as U_bnd
| eval dmbs=D_bnd*8/1000000 
| eval umbs=U_bnd*8/1000000  
| table _time dmbs umbs

This is the basic result, I don't want to to an avg(dmbs) so timechart wont work that I am aware of. 

What I would like is to do like a span=30m to join these while showing a label for the server.name for each bar. Is this possible or do I have to make three chart searches then combine somehow?

Expected Result I am trying to make is like a time chart avg(dmbs) span=15 but with each server.name in series so I can overlay them or use the trellis layout and aggregate them on the server.name while still showing the up/down speed. i don't care if the up/down is side by side or stacked. The span will eliminate the gap between the times (30min).

I did this on one server.name and works fine but want to combine all three server.name in one chart in different x data points.

Does this help?

| bin _time span=30m
| chart values(dmbs) as dmbs values(umbs) as umbs by _time server.name

perfect, thanks. need to learn that bin function...
