Ignoring minutes with no data in generated charts

[rtanay (Ryan Tanay)]

I’m using Graylog to graph database metrics received periodically from several Heroku database log drains and am running into an issue.

The problem is the logs only arrive roughly once per minute, and as such sometimes I end up with minutes with no data received. Not really a problem for the data itself, but in the graphs all data from that minute shows up as a zero which is less than ideal:

Is there any way to get the graphs to ignore/not render a data point for minutes that don’t contain any data?

does this log messages contain a timestamp? use that instead of the timestamp with the arrival time of the message in graylog.

It does, but those timestamps match the arrival time (sans time zone). The actual messages are only generated roughly every minute.
