It looks like it will be supported in Kibana4, but there doesn't seem to be much more info out there than that.

Is it Possible to Use Histogram Facet or Its Curl Response in Kibana
I have a HDMI -> VGA cable for my Pi that works well when I want to use it.

The cable stays slightly warm even when not in use, but connected - I would like to know if it's possible to "shut down" power to the HDMI port if/when there is no activity - like a computer going to sleep (does the Pi sleep? - I usually just turn off the monitor) - or does the cable draw power from the VGA side via the turned-off (but not unplugged) monitor? 

I am running raspbian in CLI mode, no GUI, so some of the screen-saver settings/graphics may not apply or be available to me.
