Cluster graph with 0 columns uses incorrect scale for summary graphs

[maplebed]

When 0 columns is chosen in the cluster view, the host detail section has one host per row, with the first column being the chosen metric and the 4 columns to the right showing the 4 summary graphs.

When Scale: is set to 'same' (the default), the 4 summary graphs are scaled the same as the chosen metric. This is always incorrect, as graphs like the cpu summary should always be scaled to 100%, etc.

Example: http://ganglia3-tip.wikimedia.org/?r=20min&cs=&ce=&m=bytes_out&s=by+name&c=API+application+servers+pmtpa&h=&host_regex=&max_graphs=0&tab=m&vn=&sh=1&z=large&hc=0

Note that when 'Scale: Auto' is set, the summary graphs appear appropriately.
