Looking at the matplotlib source code, here's how they figure out levels in contour/contourf: https://github.com/matplotlib/matplotlib/blob/714d18788320325d0bff75184f62d472f67ceb91/lib/matplotlib/contour.py#L1143

It looks like they use MaxNLocator to do this: http://matplotlib.org/api/ticker_api.html#matplotlib.ticker.MaxNLocator

It should be pretty straightforward to use that here.
