The trick is:
aChart layoutOptions yOriginIsZero: false

But even then, it will not look like what I and probably you will
expect it to look like. An example for line charts
http://media.liquidx.net/js/plotkit-tests/quickstart-neg.html

Only if you use line charts without filling but stoking, then negative
values should look ok.

Very sad... And thanks for the tip. I'll try it with the bars.
