Empty labels in Timelion are handled incorrectly

[tommikiviniemi-srs]

Kibana version:
5.2.2

Elasticsearch version:
5.2.2

Description of the problem including expected versus actual behavior:
Using the .label() expression in Timelion with an empty string (correctly) prevents the label from being drawn, but all consecutive labels’ values are offset by one.

In the first image there's a line for iOS, and another line just for the .points() part. All queries have labels so this works properly:

Now we hide the .points() line's label:

Both charts render correctly. First look at the labels in the first image, iOS shows 7 and Android 2, this is correct. However, now look at the labels in the second image, Android's label shows what would have been shown in the HIDDEN label. This is very dangerous as all consecutive labels after the hidden label will show bogus values.

+1 still a bug in Kibana 6.2

+1 Any chance this will get addressed? Showing incorrect values in the label (but showing the correct name) is really misleading

@stratoula, It was fixed in new implementation of timeline but it still reproducible for old implementation. Can we close it?

[stratoula]

As it has been fixed in the new implementation, yes we can close it :)
