Title: Fix for #1117

A fix for Issue #1117 (Null points cause the autoscale option to be ignored when using `fillBetween`).

Setting `defaultValue` to `null` (unless we are drawing bars) fixes the problem. That way the `min` value for the y-axis is not floored to zero before `fillBetween` gets the chance to run its hook and set actual bottom values.
