Explanation

On a datetime chart, if smoothing is enabled and the serie type is area, if any of the data is null in the timeserie, there is a glitch in the filled area (it seems misaligned by some pixels whenever it has a point to display) and also the initial animation is broken.

• With straight:
  

• Without null in the dataset:
