I am currently running kibana 5.6.2 and I can't draw data as line in timelion. Though, I'm able to draw my data with points and bars. For instance, .points(radius=3,weight=1,symbol=cross) would work but .lines(width=1,show=true) would not. Yet, when I hover the mouse on the graph, it still manages to show the value of the specified point in the legend, even if no graph is displayed.
I should also say that I only have this problem when I use the "metric" parameter in the es function. I'm able to draw my data as lines when I don't use this parameter.
I tried to look for some config parameters in kibana management panel but I didn't found anything. From what I've seen on the internet, nobody seem to have the same issue either with this kibana version.
If anybody has an idea on how I could solve this problem, the help would be greatly appreciated.
