By default, **ProPlot** uses the `long_name` attribute of a DataArray as a `title` of the figure, but not the `units` attribute. Here is the default behavior of **Cartopy** when doing a plot (data: [ens_avg_snow_cyclic.zip](https://github.com/lukelbd/proplot/files/3922734/ens_avg_snow_cyclic.zip)):\r\n\r\n```python\r\nimport xarray as xr\r\nimport proplot as plot\r\n\r\nens_avg_snow_cyclic = xr.open_dataarray('ens_avg_snow_cyclic.nc')\r\nens_avg_snow_cyclic.plot()\r\n```\r\n![cartopy_units](https://user-images.githubusercontent.com/20254164/70157882-9ea9ab80-16b6-11ea-92d6-c4502c693b14.jpg)\r\n\r\nIt automatically puts the `long_name` and `units` attribute of the DataArray beside the color bar. In addition, it writes as a title the coordinates left (I didn't do any projection, the goal is only to show the labels here).\r\n\r\nIt would be nice to at least have the `units` after the title in **ProPlot** too, in addition to the actual default behavior shown here:\r\n```python\r\nf, axs = plot.subplots(proj='cyl', width=8)\r\n\r\nm = axs[0].contourf(ens_avg_snow_cyclic, cmap='BuRd')\r\n\r\nf.colorbar(m)\r\n\r\naxs.format(\r\n    geogridlinewidth=0.5, geogridcolor='gray8', geogridalpha=0.5, labels=True, \r\n    coast=True, ocean=True, oceancolor='gray3', latlim=(20,90),\r\n    suptitle=str(ens_avg_snow_cyclic.season.values) + ' climatology'\r\n)\r\n```\r\n![proplot_default](https://user-images.githubusercontent.com/20254164/70158201-242d5b80-16b7-11ea-9a4f-deb705182cb0.jpg)\r\n\r\nLike for example (here are 3 different possibilies I am thinking):\r\n![proplot_default_1](https://user-images.githubusercontent.com/20254164/70158278-458e4780-16b7-11ea-839f-f632d32c8bb3.jpg)\r\n![proplot_default_2](https://user-images.githubusercontent.com/20254164/70158287-47f0a180-16b7-11ea-9bf2-0c52f274ce38.jpg)\r\n![proplot_default_3](https://user-images.githubusercontent.com/20254164/70158290-4921ce80-16b7-11ea-9f7f-3b2b9db6c0f5.jpg)\r\n\r\nOr having the same behavior as **Cartopy** like the 2nd example and putting as a title the left coordinates as `coord_name = values`. Here it is the season, but usually, if we select a date, it shows `time = ...`. After it doesn't have to be like Cartopy, in my opinion adding at least the units would be already nice :)\r\n","author":{"url":"https://github.com/mickaellalande","@type":"Person","name":"mickaellalande"},"datePublished":"2019-12-04T16:07:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/81/proplot/issues/81"}
