## Modifying matplotlib.rcParams
You can mutate the `rcParams` dictionary that Matplotlib uses for global parameters following this example:
```jl
rcParams = PyPlot.PyDict(PyPlot.matplotlib."rcParams")
rcParams["font.size"] = 15
```
(If you instead used `PyPlot.matplotlib.rcParams`, PyCall would make a copy of the dictionary
so that the Python `rcParams` wouldn't be modified.)
