axisLabelDistance attribute is not working when i use rotateLabels to rotate the ticks on x-axis with angular nvd3

Question

I am using a simple line chart using angular nvd3, i am using dates as ticks on x-axis and i want some space between ticks and axis label. For that i use axisLabelDistance: 100, to maintain the gap, and it is working fine. My problem is when i use rotateLabels: 15 to rotate the x-axis ticks then axisLabelDistance is stopped working.

Here is example plunkr

I need some more gap between the ticks and the axis label. Thanks
