Datetime x-axis with timeline enabled breaks x value distances

Hi!

In this example below, we have a few items with irregular x values.
http://demo.vaadin.com/charts/#TimeDataWithIrregularIntervals

But if I enable the timeline for the chart, then all the distances on the X-axis will be equal. So the distance between 15. Nov and 27. Nov is equal to the distance between 27. Nov and 30. Nov.
This doesn’t look good, and I couldn’t find any way to solve this issue.

Am I missing something?
