I am trying to make a relatively complicated graph in Gadfly, and am
struggling.
This is some sample data with the same structure as my data.
~~~
julia> t = readtable("testdata.csv")
9x5 DataFrame
|-------|---------|------|-------|--------|--------|
| Row # | _type | rank | speed | thing1 | thing2 |
| 1 | "red" | 1 | 10.0 | 0.0 | 0.0 |
| 2 | "red" | 2 | 11.1 | 0.1 | 0.2 |
| 3 | "red" | 3 | 12.4 | 0.3 | 0.0 |
| 4 | "green" | 1 | 8.0 | 0.2 | 1.0 |
| 5 | "green" | 2 | 7.0 | 0.1 | 0.5 |
| 6 | "green" | 3 | 9.0 | 0.2 | 0.0 |
| 7 | "blue" | 1 | 1.0 | 1.0 | 1.0 |
| 8 | "blue" | 2 | 2.0 | 0.2 | 0.2 |
| 9 | "blue" | 3 | 3.0 | 0.1 | 0.1 |

Currently, I am trying to make a plot with three rows; each row has a plot
with two layers. The rows are by :_type. The x-axis for everything is
:rank. The two layers should be scatterplots of :thing1 and :thing2.
I have tried several variations, here is one of them:
~~~
julia>
plot(t,Geom.subplot_grid(Geom.point),ygroup=:_type,layer(x=:rank,y=:thing1),layer(x=:rank,y=:thing2))
Error showing value of type Plot:

How do I put layers inside a subplot?
Thanks,
