[SOLVED] Memory usage graph in GUI

Currently the memory usage graphs in GUI show used amount which includes also (file) cache which (at least in my case where the dataset is larger than ram) makes them somewhat uninteresting (as it's just a straight line):

While the actual guest stats are different - only ~10G used the rest is linux filecache

Code:
lxc-container:~ # free -m
             total       used       free     shared    buffers     cached
Mem:         20000      19865        134        129          0       9063
-/+ buffers/cache:      10801       9198
Swap:            0          0          0

Would there be a way to tweak the graphs (at least for LXC containers) to show also the 'cached' amount or 'used' without the cache or are there some caveats (like for example Windows guests) where the usage is not reported in details to the host/hypervisor?

Generally it's not a big problem since the guests are monitored also from within but in my opinion it would be a usefull (visually pleasing) feature to quickly see from the Proxmox GUI if some instance is not actually starving out of memory.
