Hi everyone, not sure if this is the correct place to ask questions - but here goes.

I have data in elastic search relating to network data. Netflow data if you will.  
Ip1 -\>number of bytes -\> ip2

I'd like to graph the transfer rate in a line chart , but cant figure out how to achive this. Maybe its not possible (yet?)

Obviously I can add a scripted field (or just precalculate when indexing the document) - bytes \* 8 / interval = bits per second.

But because the x-axis interval changes - this calculation doesnt work if the graph interval does not align with my data/scripted field interval.

The second part to is that Ideally I'd like the y-axis to display in b/s , kb/s, mb/s etc.  
Scripted fields only seem to support Bytes.

Regards.  
Pieter
