How to display 2D probabilistic map in rviz?

edit

I have a probability grid that I use as a map in my application.

How can I display this in rviz? Does the rviz map plugin supports probability values or only the states unknown, occupied and free?

Is there any other option on how can I show this map in an user friendly way?

I found this question here Rviz display 2d probabilistic map, but, since it's from February 2012, I wanted to get a more updated answer on this topic.
