If you use a continuous date you can manually set the date as far in the future as you want in the Edit Axis diag box.
Do you mean by setting fix range on Edit Axis?
What I really need is like showing all the filtered values with or w/o data. For example, when my filtered date range is Jan 2013 - Dec 2013, I want to see 12 header labels for the 12 months even my last sale is on May 2013. Is that possible?
