I'm putting together an area chart where values can fluctuate a good deal from one to the other, resulting in many spikes, rather than a smooth, gradual chart. The problem I'm finding is that the anti-aliasing option only affects the trailing edge of the spikes, leaving the leading edge to be very jagged [see attached image].

I haven't been able to find an already-existing solution, but it seems like an obvious enough problem that it would have been addressed already. Has anyone run into this before? Using pChart 2.1.3.
