[FIXED] AttributeError: 'AxesSubplot' object has no attribute 'coastlines'

Issue

ds_mm=gb.mean(dim='TIME')
ds_mm

Data description is given here:

ax= plt.axes(projection=ccrs.PlateCarree())
pp=ds_mm.ILD_T05
p=pp.plot.contourf(   
    x='LON86_140',
    y='LAT71_110',
    col='month',
    levels=30,
    col_wrap=3,
    cmap=plt.cm.rainbow,
)

for ax in p.axes.flat:
    ax.coastlines()

I am getting the contour plots correctly but while trying to add coastlines through a for loop it shows attribute error.

AttributeError: 'AxesSubplot' object has no attribute 'coastlines'

Solution

You have not created the contour plots on axes with the cartopy projection. To do this, use the subplot_kws argument to xr.DataArray.plot, e.g.:

pp=ds_mm.ILD_T05
p=pp.plot.contourf(   
    x='LON86_140',
    y='LAT71_110',
    col='month',
    levels=30,
    col_wrap=3,
    cmap=plt.cm.rainbow,
    subplot_kws={'projection': ccrs.PlateCarree()},

)
