in recent days you've got changed look of this graph, and now, i must say, it looks pretty good. but for someone who is participating in few projects it can be unreadable. I suggest you to give it more colours. In a graph of mine, there's 9 projects (8 shown), and few project has the same colour (seti and LHC). in my opinion there should be a minimum of 10 different colours.
And second suggestion is, as was said few days earlier in a shoutbox, that those project should be sorted by percentage...

i hope you will understand me, and in few days i will be able to see changes.

There are 12 colors defined for the pie chart (since monday).

All piecharts are now sorted from hight-to-low percentage.
