Take a look at this example http://matplotlib.sourceforge.net/examples/api/date_index_formatter.html It's trying to solve a different but related problem: in financial time series you only have data on Monday - Friday, and you don't want to plot the gaps on weekends. So you plot the data linearly with an index, and use a custom locator and formatter to set and format the ticks.
