Cool. I really like it. One thing that I stumbled upon was that, when I was playing with negative numbers on slide 6 I would have expected the x-axis to stay at zero and the line to dip below it.

But I am not really sure how to achive this for the secondary y-axix (I was playing with the percentages and simulating negative growth).

Good spot, it does look like a bug when you are using 1 axis. I'll roll a fix in the next release today. Thanks for the feedback.
