I started to look at this, but ran into GiovineItalia/Compose.jl#348 i.e. there's an issue with the fill property for svg text in Compose.

The workaround I currently have is: ```julia # Mock tick_label function fraction_π(x) = string.(round.(x/π, digits=1), "π") sinf(x,y) = sin(x)*sin(y) p1 = plot(z=sinf, x=range(0, 2π, length=20), y=range(0, 2π, length=20), Geom.contour, Coord.cartesian(ymin=0,...

Regression testing showed 1 difference: testscripts/auto_enumerate.jl shows `Geom.line` layer but no `Geom.bar`. Will investigate.

I don't think a `facet_wrap` has been implemented in Gadfly. But here is an example (also see #841 for another way). ``` julia using DataFrames x = linspace(-2, 2, 11)...

Nope, no `facet_wrap` yet. Currently changing some internal code (#1520) which might make the development of `subplot_wrap` easier.

Note that there's also `Geom.segment` which got an update in #1465. `Geom.segment` could be used to do the lower plots above (albeit both x/xend or y/yend need to be specified)....

Here is an attempt at a (near) publication-quality scatterplot matrix for Gadfly. You can find this on the branch scatplotmat at http://github.com/Mattriks/Gadfly.jl. I'll do a PR soon. The function `scatterplotmatdata`,...

Can you give an example of what you are trying to do in your 3rd dotpoint? It's definitely possible to mix Compose graphics and Gadfly plots.

For text, this would be easy to implement: 1. Add 5 new Theme fields: `major_label` (or `major_label_text`), `minor_label`, `point_label`, `key_title`, `key_label`, which will accept the new struct in 2. 2....

The way to do this would be similar to #1458,. Make a new struct like: ```julia struct BoxFormat fill stroke linewidth etc end ``` which could be accepted by new...
