It's a little piece of code called gdchart. I'm betting that it's actually by design,
to leave enough room for the legends.
The only ntop choice is to limit the # of segments.
The ntop code is in graph.c -- for example, look at hostTrafficDistrib(). Look around
410... after the array is loaded.
Add something like this:
quicksort(...);
if (num > 5) num = 5;
numLittles = 0;
for (i=num; i>=0; i--) {
if (p[i] < 0.025) numLittles++
}
if (numLittles > 3) num = num - numLittles + 3;
Of course it's not that simple since quicksort wants a struct with the two fields in
it and gdchart wants two separate arrays.
Good luck...

The actual bug that I saw was the
1. diameter of the pie gets reduced as the numnber of
slices increses
2. the center of the each slices gets farther and
farther away from the biggest slice.
One other solution is to "explode" the pie so that the radial distance between the
slices is incresed, this will make it more readable when their are lots of slices.
If you can tell me where exactly to look inthe code I can make a small try to fix this
:)
