I would call this coastlines instead of shapes. Much clearer.

[yklpaul0902]

Since other functioms like geo_bin_from_array(), geo_scatter_from_array(), etc, they all name them as shapes for turning on/off the plotting of coastline, I would suggest either having it as shapes in geo_im_from_array(), or renaming all relevant shapes as coastlines, to make it more consistent.

[chahank]

Ok, let it be shapes then. It is a very bad name, but consistency of code is probably more important.

[chahank]

Can you please update the changelog?

And could you post a picture of a plot without the shapes just to see that it is working?

[yklpaul0902]

shapes=true (by default)

shapes=False

[chahank]

Perfect. Then, please just update the CHANGELOG.md file.

@yklpaul0902 : many thanks for the contribution! 😃 The failing compatibility test is unrelated and due to a (hopefully) temporary unavailability of the ECMWF ftp server. Hence: ready to merge.
