Kibana color visualisation

Hello
it is possible now to modify colors on visualization.
how to do that on splited chart?
is it possible to extend that possibility when you split chart ?

This is possible in Kibana 4.4

Ah ok great so i wait for kibana 4.4.4

with graph it is useful to set a threshold
do you know if there will be soon a possibility to set one or multiple threshold ?

thanks
