At least if we write it as for other regular 2D data with x, y, as in the documentation example: https://proplot.readthedocs.io/en/latest/customizing.html#Shared-and-spanning-labels. \r\n\r\nHere is an example (data: [season_clim_diff.zip](https://github.com/lukelbd/proplot/files/3921148/season_clim_diff.zip)):\r\n```python\r\nimport xarray as xr\r\nimport proplot as plot\r\n\r\nseason_clim_diff = xr.open_dataarray('season_clim_diff.nc')\r\n\r\nf, axs = plot.subplots(\r\n    proj='cyl', proj_kw={'lon_0':180}, ncols=2, nrows=2, axwidth=3, share=3\r\n)\r\n\r\nseasons = ['DJF', 'MAM', 'JJA', 'SON']\r\n\r\nfor i, ax in enumerate(axs):\r\n    m = ax.contourf(\r\n        season_clim_diff.sel(season=seasons[i]), cmap='ColdHot', norm='midpoint'\r\n    )\r\n    ax.format(title=season_clim_diff.sel(season=seasons[i]).season.values)\r\n    \r\nf.colorbar(m, label=\"Snow Area Fraction [%]\")\r\naxs.format(\r\n    geogridlinewidth=0.5, geogridcolor='gray8', geogridalpha=0.5, \r\n    labels=True, lonlines=60, latlines=30, \r\n    coast=True, ocean=True, oceancolor='gray4',\r\n    suptitle=\"Annual snow cover bias (IPSL versus Rutgers)\", \r\n    abc=True, abcstyle='a.'\r\n)\r\n```\r\n\r\n![proplot_subplots_share](https://user-images.githubusercontent.com/20254164/70132009-9c7a2980-1683-11ea-8611-0893288d64e8.jpg)\r\n\r\nThus, with the `share=3` option I would expect that the longitudes labels of the first line and the latitudes labels of the last column won't appear.\r\n\r\n","author":{"url":"https://github.com/mickaellalande","@type":"Person","name":"mickaellalande"},"datePublished":"2019-12-04T09:56:45.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/79/proplot/issues/79"}
