See it here: http://allopensensors.com/author/andreas , the third chart,

Answer 1

On the other charts you have the line categoryAxis.parseDates = true; commented out, on the third chart is isn't. This will provide you with the axis to match the others.
As you have time data then the charts do look better in my opinion with the axis as they are in chart 3. I would personally remove the comment from the other charts to match this one.
