I am trying to get it to work but I don't succeed:

 

I want to display outside temperatures for a complete year with 1 hour interval values. (so I have 8760 value pairs).

for the horizontal axis I use a DateTime axis. But I have trouble setting the right settings for the horizontal axis.

I've set the MajorStep to 0.125 to display the majorgridlines each 3rd hour.

But I don't get the Minor gridlines to display. (settting MinorStep to 0.04166666666)

Any suggestions ?

I checked in a little change that let you set the MinorStep on the DateTimeAxis.
