---------------------------------------
thanks !
I have also thought about more than one task per bar, and was going to
implement it, but then i gave up the idea. The reason for that is the progress
for reduce tasks is three phases(0-0.33, 0.33-0.66, 0.66-1.0). And i normalize
each progress for each phase to 0 - 100 interval. But if we average over a few
reduce tasks, then the progress(in the interval 0-1) will not correspond to
actual phases. For example if we average over 0.0 0.60 and 0.90, then the bar
should have 0.50, which means the bar will show sort phase, but actualy only
one of the tasks is in sort.
I am in favor of keeping the graph compact, but i still cannot figure out how
to group tasks together. Any ideas ?
