Kibana: Timelion: Cannot read property '1' of undefined - can't call .fit() after using split

Kibana version: 5.1.2

Elasticsearch version: 5.1.1

Server OS version: TBD

Browser version: 55.0.2883.95

Browser OS version: Mac OS X 10.12.3

Original install method (e.g. download page, yum, from source, etc.):

Description of the problem including expected versus actual behavior:
When entering into timelion the following expression: .es(q=name:my_thing,metric=sum:gauge.value,split=status:5).fit(none) I would like the fit() function to be applied on each of the 5 timeseries that are returned through the split. Instead I am receiving a red alert at the top with "Timelion: Error: in cell #1: Cannot read property '1' of undefined". When clicking on More info, I am getting this trace:

I think it's the presence of zeros in the data that causes .fit() to choke. Here is a simpler expression that triggers this error: .static(0).fit(none)

[tommikiviniemi-srs]

Any chance of this getting fixed? This prevents us from properly creating a lot of charts we'd need, and it's very hard to communicate to teams what to avoid doing.

[carlosvega]

Yes, it's the presence of zeros. One awful workaround for this is:

.add(0.0001).fit('average').subtract(0.0001)

Avoids the error. And surprisingly, it looks better. Here is a pic. Top chart shows the result with the trick, bottom chart shows it without it.

Please address this bug. While the workaround suggested by @carlosvega helps in some cases, it exacerbates Timelion's existing problems of sparse documentation and expressions that are esoteric/unreadable.

I'm also seeing Timelion: Error: in cell #1: Cannot read property '1' of undefined when a Timelion graph is added on a dashboard and a filter is applied which returns zero results.
