Line chart seems not working as expected after c3 upgrade to 0.4.11

Are there any config changes required to use latest c3(0.4.11)?

C3 **0.4.11**: (With same configuration)

Start by comparing the two linked JSFiddles, which reproduce the line chart with C3 0.4.10 and 0.4.11 using D3 3.5.17. Identify what changed between the versions and determine whether a configuration change is required; done means the same configuration produces the expected line chart on C3 0.4.11.
