WQ Henry example fails at plotting

Apparently with the deltaforge 0.2.0 installation:

Start with the Henry.py example and inspect the plotting call at line 150, where conc.plot raises the reported Matplotlib error under deltaforge 0.2.0. Run the example in that environment and verify that the Henry plot completes without the unexpected-keyword exception.
