Hi,

I am monitoring temperature and I want to display the last 24 hours. I need the x axis to look like this:

-24    -18    -12    -6    0       -The label intervals aren't really important.

But because the datapoints are every minute, there will be 1440 data points or intervals on the x axis.

But I can't change the labels into minus hours rather than minus minutes.

I wrote this out once with a lot more detail but I lost it when I clicked post so I''m keeping this one short.

Thanks,

Marc
