Description:
------------
The Memory Usage diagram in Host Status Diagrams has green + brown slices only cover something like 50 % of the whole circle covered in total when there are many fragments; it seems that the graph building is unable to draw the graph correctly. The numbers below it tell that there's 37.5 % free and 62.5 % used, which totals up correctly.

Expected result:
----------------
A full circle with brown and green slices.

Actual result:
--------------
