I still like my idea ;) :P But that'd be a pretty cool thing to do.

yeah I know. I mean it would be much harder to draw I think, unless you make your own circle routine, which would be slower in BASIC

Yeah, it is slow (first screenshot is original at 6MHz, second is exploded at 6MHz, third is original at 15 MHz, fourth is exploded at 15MHz):

That's still pretty cool though, regardless the speed :)

YES!!!!!!! No timer string though :P

The only thing about your exploded one is that when you get to less than ten elements in the list then the offset of the chart is really noticeable.

Yeah, the small ones are really close together because I'm not accounting for the space between the pieces, like most computer-made exploded pie charts do. They all start five pixels away from the center.

Oh, no. I'm not talking about that. I'm talking about how if you have like {38,95,99→L1 it will look like the thirty-eight piece is sticking out further than the others.

Eh? Really?

EDIT: Oh yeah, because there's more of a bump since it's smaller, and should technically have a smaller radius.

Can't really do anything about it :P At least it's better than before, when I simply connected the two bars with a straight line. Fast, but not exactly pi-like pie-like.

At first, instead of having a little routine to draw the curve of each section, I just used a straight line :D It looked more like shards of glass than like an exploded pie.
