Graph with Multiple Vertical Axes #8

FYI:  I originally posted this same question at the above link.

Hello,

I'm trying to create a single graph with multiple metrics 
(ex: CPU%, RAM, response time, throughput).  

Hoping that you can recommend an approach.

Each metric needs to have its own vertical axis.
The horizontal axis will be elapsed time.

JFreeChart includes an example of this kind of graph.
See the attached "JFreeChart-time-series-line-graph-with-
multiple-vertical-axes.PNG" for an example.

1) Could you describe what it would take to do this with 
rrd4j out-of-the box?

2) If a) isn't possible, could you suggest an approach for 
doing this with the data in rrd4j and doing the graphing 
with:

   a) with a _java_ graphing library (perhaps JFreeChart).

   b) with a NON java graphing libary (like     
http://flare.prefuse.org/demo).

Thanks, looking forward to trying rrd4j.

 kelleyastover, can you provides a patch, some samples and documentation ? A fork on google or github would be very helpful.

I did a first pass at merging kelleyastover's multi-y patch:

https://github.com/brharrington/rrd4j/tree/multi-y

There were quite a few changes in 2.3 since the patch was made so I'm not 
entirely sure I merged everything correctly, however, the demos (Demo and the 
added MultipleYAxis) run and the images look reasonable at first glance. Output 
from MultipleYAxis demo is attached.
