Plotting example from documentation fails

[noahrhodes]

I am getting the this failure using the example from the Raster.jl docs

The example works in v0.8.4, but fails in v0.9.0

using CairoMakie, Makie
using Rasters, RasterDataSources, ArchGDAL
A = Raster(WorldClim{BioClim}, 5) # this is a 3D raster, so is not accepted.

fig = Figure()
plot(fig[1, 1], A)
contour(fig[1, 2], A)
ax = Axis(fig[2, 1]; aspect = DataAspect())
contourf!(ax, A)
surface(fig[2, 2], A) # even a 3D plot works!
fig

I think this is a duplicate of #518.

[noahrhodes]

This issue appeared in Julia v1.8. It does not occur in Julia v1.9

Interesting I'll take a look. Not sure what could be different 1.8/1.9...

But there are still some problems with DimensionalData.jl and color plotting that need fixing that may or may not fix this.
