dateAxis.tooltipDateFormat = "YYYY/MM/dd HH:mm";
// Setting up label rotation
dateAxis.renderer.labels.template.rotation = 45;

Answer 1

You are setting format for a "day", while your DateAxis is in "hour" mode. You need to set it for that. While you're at it make sure you set for period change as well:

dateAxis.dateFormats.setKey("hour", "YYYY/MM/dd hh:mm");
dateAxis.periodChangeDateFormats.setKey("hour", "YYYY/MM/dd hh:mm");

Make sure your read this about formats on DateAxis.
