Datetime 12 hour interval puts label on 12:00 noon rather than 12:00 midnight

Question

I have created an area chart that a x-value for each hour in a specified range.  The X-axis settings are as follows:
Interval = 1
IntervalType = Hours
MajorGrid.Interval = 12
MajorGrid.IntervalType = Hours
LabelStyle.Interval = 1
LabelStyle.IntervalType = Days

I want the date to always show up under the MajorGrid line for midnight, but by default, it is showing up under noon.  I am able to correct by setting the LabelStyle.IntervalOffset = -12, but this behavior seems counter intuitive to me.  Has anyone noticed this behavior or think of something I am doing wrong?

Answer 1

Can you post a pic? Sounds right to me... I would think 2, 4, 6 showing by default, and you want 1, 3, 5 ... have to go back and look at mine now. I just kinda take the defaults on most of them, which means a granularity of a half a day isn't that important to me.

Answer 2

As it turns out, I went back and removed the -12 hour offset I had on the X-axis label, and it is now showing the date label on the midnight hour rather than noon.  The reason this is important in my case is I am not displaying the actual hours and the date label is the only way to orient ones self with the data.    Here is an example of what it now looks like and why the date is important.  I'm putting a major grid every 12 hours, but only want the date label once per day on the midnight hour.  The image was taken around 11:30AM so the label is correct.

It is now working as expected, but I will continue to monitor as I don't know what changed the behavior.
