Boris,
Can you open a bug for problem 2? I do not see what you are referring
to in problem 1.

Hi Jason,
Thanks for the answer.
I will open a bug for problem 2 and will publish its number there.
I will try to describe first problem in details.
Pie chart consist from slices, each slice has value that defines size of
the slice. When we move mouse over each slice, tooltip has to be shown
and by default it shows value of the slice under it, but when I have
many slices I see wrong tooltips (sometimes I can reproduce it with less
number of slices), I see tooltip from other slice. For example on the
picture I keep mouse over slice with value 19456, but see value 10506
(this slice is located above), so I think that there is a bug in the
algorithm defining slice using mouse location and it is reproduced only
for SWT renderer, I have verified it in PNG with image map and all
tooltips are shown correctly.

I see now. Please open a separate bug for this. Thanks

Hi Jason,
I've opened bug for the second problem
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=303720).
And I've found bug for the first problem
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=285851), but as I
understand it wasn't fixed correctly, because it can be reproduced now.
Shall I reopen this issue?

You can re-open, but it sounds like a limitation with SWT.
