Ticket #1040 (new enhancement)

Description

On the report, within the monitor section, reversing the axes on the mem graph would give us a more readable graph since we woumd have zero (0), as no more memory available, at the bottom of the graph so that we could see more clearly how many CU the node can't handle until the node's running out of mem.

The curve will look like this :

Available MEM

|_
| _
|  -       - .....
|    -   -
 0 ____- _____________
  1 2 4 8 16 32         (CU)

We could have on the left :

• cumulative : RAM + swap
• RAM only
• swap only

Hope it makes sense.
