I get experience with qwt and now I understand that my suggestion to use qwt library is not really good solution. qwt itself is not so lightweight library (qwt 6 is 1.1 Mb large) and it's not so widespread... Also there are different versions of qwt in different distros.
Qwt is really powerful instrument for making almost any kind of plots. But it's not good solution for bittorent client.
I guess it should be possible to implement some really simple graph widget for representing speed data.
