Grafana renders wrong series data based on the enabled series

[farcaller]

(I figured out that gh is a better place to ask question than so; and this one actually looks like a bug)

I have a grafana installation backed by influxdb. I'm trying to get aggredated view on my docker containers, but for some reason grafana renders false data.

Here's a sample query generated for one of the series in grafana:

select mean(mem_rss) as mem_rss_mean from docker_job.web.zinc where  time > now() - 5m     group by time(0.1s) order asc

Now, running it in influxdb produces reasonable output:

    time            mem_rss_mean
    1403967908700   1.6328125
    1403967968900   1.6328125
    1403968030500   1.6328125
    1403968088600   1.6328125
    1403968148800   1.6328125

And it looks correct in grafana:

Now, when I add series (actually I just enable them, they're already added but are disabled for the screenshot) the value magically tops:

Any ideas what's going wrong in here?

PS: It works fine with one or two enabled series, but usually screws up when I enable third or fourth.

Thanks for reporting this. Will try to remember to make a habit of checking SO for grafana questions.

The hover shows a job.web.zinc value of 467, and not mem_rss_mean. Is job.web.zinc not 467?
The only reason for a jump I can think of is the the display option "stack" (in edit mode, styles tab).

Gah! Yes, it was the 'stack' option, thanks.
