Addition to previous message:
I found part of the solution: The minorGridInterval should be set at 21600000, which is 3600 x 6 x 1000.

Now I still have find a way how to let the minorGrid fall over the majorgrid. This is due to the fact that I calculate the start (minimum) as being “new Date() – 86400000 x 14” (14 is for last 14 days.)
