Hey
I'm trying to get things work in ELK. So far I created a index ('undefined') and also a pattern ('unde*'). Inside the index I am having data like this:
Measurement.Distance
Measurement.Force
Message.Timestamp
Message.DMC
If I try to create a line graph (normal one), Kibana does alwas combine Measurements of distance with digits to one number. This renders the Forcegraph unusable, since I am having much more values.
As a workaround I did Measurement.DistanceX100=100*Measurement.Distance at the ingest  then I get charts I could use. But this is a bad way to fix this.
I tried with VEGA so far ... and also did a CANVAS which acktually worked quite fine but there I cant use dashboards.
SELECT Measurement.Force as y ,Measurement.Distance as x, Message.Product.DMC AS dmc FROM "unde*"
I would need a bit of help building the VEGA code... this is how far I got ... but still receiving the INFINITY Error....

Infinite extent for field "Measurement.Distance": [Infinity, Infinity]

Infinite extent for field "Measurement.Force": [Infinity, Infinity]
It's really not that easy to understand without more examples. I would be glad to get some hints.
