subplot_grid + titles ?

[edljk]

Does it exist a way to associate to every plot of a subplot_grid its own title (eventually depending of the dataframe for instance) ?

Maybe:

using RDatasets
data = dataset("datasets", "CO2")
labels=["Title 1", "Title 2", "Title 3","Title 4" ]
titledata = DataFrame(label=labels, x=500, y=58, 
    Type=unique(data[:Type])[[1,2,1,2]],
    Treatment=unique(data[:Treatment])[[1,1,2,2]] )
coord = Coord.cartesian(ymin=0, ymax=60)

p=plot(data, xgroup=:Type, ygroup=:Treatment,
Geom.subplot_grid(coord,
    layer(data, x=:Conc, y=:Uptake,  xgroup=:Type, ygroup=:Treatment, Geom.point),
    layer(titledata, x=:x, y=:y, label=:label, xgroup=:Type, ygroup=:Treatment, Geom.label(position=:centered)),
    Guide.yticks(ticks=collect(0:10:50))
),       
    Guide.title("Title of Plot"),
    Guide.xlabel("Concentration"),
    Guide.ylabel("Uptake")
)

[Mattriks]

Note that because I have now added data, xgroup=:Type, ygroup=:Treatment in the first line of the plot statement, it is possible to remove these from the first layer:

layer(x=:Conc, y=:Uptake, Geom.point)

for tidier code.

Perfect, thank you very much !
