Describe the bug
Categories are calculated as numbers when DateTime is used.

To Reproduce
Steps to reproduce the behavior:

  1. Use a DateTime property for the category value. RadzenChart would treat them as numbers which leads to unexpected results - dates from the same month are used as ticks, months are skipped etc.

Expected behavior
RadzenChart should try to generated user-friendly ticks from dates - detect what a "nice" interval would be - decades, years, months, weeks, days, hours etc.

Additional context
Check how other charts do that and deduce an algorithm.
