-```

-### Two-axis
-
-Use the `axis` or `axiss` arguments.

-
-Plot multiple series with different numbers of points.  Mix arguments that apply to all series (singular... see `marker`) with arguments unique to each series (pluralized... see `colors`).

-
-### Subplots
-
-  subplot and subplot! are distinct commands which create many plots and add series to them in a circular fashion.
-  You can define the layout with keyword params... either set the number of plots `n` (and optionally number of rows `nr` or 
-  number of columns `nc`), or you can set the layout directly with `layout`.  
-
-  Note: Gadfly is not very friendly here, and although you can create a plot and save a PNG, I haven't been able to actually display it.
-
-
-```julia
-subplot(randn(100,5); layout=[1,1,3],linetypes=[:line,:hist,:dots,:step,:bar],nbins=10,legend=false)
-```
-
-![](../img/gadfly_example_12.png)
-
-### Adding to subplots
-
-Note here the automatic grid layout, as well as the order in which new series are added to the plots.
-
-```julia
-subplot(randn(100,5); n=4)
