Funcionality for plotting dates or timeseries?

[titusjan]

First of all thanks for making this library.

Is it somehow possible to make line plots where the x-coordinates are Python datetime objects or Numpy datetime64 elements?

I couldn't find anything in the documentation or source. I'm not familiar with Qwt but it seems to have a QwtDate class. However this is apparently not ported to PythonQwt.

Any help would be appreciated.
