I'm using pandas, geopandas, and cartopy to make spatial plots for data points.
Everything works fine, except for when I try to add color bar.
Below is my code and the error. Any help is appreciated.
fig = plt.figure()
ax = plt.axes(projection=ccrs.PlateCarree())
reader = shpreader.Reader('countyl010g.shp')
counties = list(reader.geometries())
COUNTIES = cfeature.ShapelyFeature(counties, ccrs.PlateCarree())
ax.add_feature(COUNTIES, facecolor='none', edgecolor='gray')
ax.coastlines()
ax.add_feature(cartopy.feature.STATES)
dp=pd.read_csv('Arash.csv',index_col=False)
def remove_minutes(state):
state=datetime.datetime.strptime(state, '%Y-%m-%d %H:%M:%S')
state= state.replace(minute=0)
return state
dp['TIMESTAMP']=dp['TIMESTAMP'].apply(remove_minutes)
dp.set_index(['TIMESTAMP'], inplace=True)
dp= dp[dp.index.day == 28]
dp['coordinates'] = dp[['Longitude', 'Latitude']].values.tolist()
dp['coordinates'] = dp['coordinates'].apply(Point)
dp = gpd.GeoDataFrame(dp, geometry='coordinates')
ac=dp.plot(ax=ax,column='CO_CMAQ',markersize=0.05,cmap='turbo')
ax.set_xlim(-119,-117)
ax.set_ylim(33.5,34.5)
fig.colorbar(ac,ax=ax)
And here is the error:
File "C:\Python-practice\GHG\spatial_plot_mobile.py", line 102, in fig.colorbar(ac,ax=ax)
File "C:\Users\akash\anaconda3\lib\site-packages\matplotlib\figure.py", line 2343, in colorbar cb = cbar.colorbar_factory(cax, mappable, **cb_kw)

Thank you again,
