The current implementation of the plot function in the land accessor is problematic in cases where the number of values is large or even continuous (e.g. a segment map with many segments).
Moreover, we have already produced a few different types of maps which have different requirements when being plotted (see #83).
the plot function in the land accessor should be able to identify the type of map being plotted and disable or adjust the labels.
In some cases this involves changing to a color bar.
Being able to disable the labels altogether should be an option too.
Some land arrays have information encoded in non-dimension coordinates, and this can only be achieved with datasets, which the accessor can't currently be used with.
