Thanks Vishwas,
Your method is much more elegant than what I had.

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.)
Thank you Vishwas,
Your solution did work. I have applied to the Y-axis of my chart and it works fine. (My Y-axis is numeric.) I have tried it on the X=axis as well, but that did’t work. X-axis is a dateTime=scale. (intervalType = “hour” and interval is 24.) I want to get a minorgridline every 6th hour.
Is that possible?
