How to plot a two-sided graph in kibana?

Question

NetFlow

Actually the question is the following - how to build a two-way channel load graph in kibana? By two-sided, I mean the graph as in picture 1.

I.e. incoming and outgoing traffic are spaced along the Y axis in different directions relative to 0.
At the moment, it has only been possible to separate incoming and outgoing traffic, but only in one plane.
