Strange Bezier Curve Drawing

If several data points have a linear growth rate, the bezier path makes it like waves, rather than a straight line

Thanks for pointing this out again, it appears that this issue was reported and then, purportedly, fixed back with Issue #21. I'm going to mark this as a duplicate for sake of clarity, but I will not close this issue because of the amount of time that has passed between both of these reports.

This is indeed an odd behavior... I'll try to think of a solution that doesn't cause too much of a performance hit. If you have any ideas, please feel free to share them here.
