为什么不能一个设置为“假”特定轴ticklabels：从cartopy-geopandas图（前xl

我有在设定的严重困难False的xlabels_top和ylabels_right从我Geopandas情节。

这geopandas情节是一个内部制作Geoaxes与创建插曲PlateCarree从Cartopy库投影。

我geopandas Geodataframe在地心测量区域系统2000（单位：度），EPSG：4989.所以我从cartopy库中创建一个大地环球对象。

下面的代码片段：

import matplotlib.pyplot as plt
import cartopy.crs as ccrs
import geopandas as gpd

Geopandas_DF = gpd.read_file('my_file.shp')

# setting projection and Transform
Projection=ccrs.PlateCarree()
Transform = ccrs.Geodetic(globe=ccrs.Globe(ellipse='GRS80'))

Fig, Ax = plt.subplots(1,1, subplot_kw={'projection': Projection})

Geopandas_DF.plot(ax=Ax, transform=Ax.transData)

Ax.gridlines(crs=Projection , draw_labels=True, linewidth=0.5, 
             alpha=0.4, color='k', linestyle='--')

Ax.xlabels_top = False nn# It should turn off the upper x ticks
Ax.ylabels_right = False # It should turn off the right y ticks
Ax.ylabels_left = True
Ax.xlines = True

Fig.show()

这里是一个图形例。 可以注意到，从上轴xticks和yticks从右侧轴尚未关闭（ False ）。

因此，我想知道这是否是Cartopy和Geopandas之间的问题，还是我做错事在我的代码。

Answer 1:

标签属于gridliner实例不是轴，可以通过存储由网格线，并设定返回gridliner关闭它们有top_labels ， right_labels如：

import matplotlib.pyplot as plt
import cartopy.crs as ccrs
import geopandas as gpd

Geopandas_DF = gpd.read_file('my_file.shp')

# setting projection and Transform
Projection=ccrs.PlateCarree()
Transform = ccrs.Geodetic(globe=ccrs.Globe(ellipse='GRS80'))

Fig, Ax = plt.subplots(1,1, subplot_kw={'projection': Projection})

Geopandas_DF.plot(ax=Ax, transform=Ax.transData)

gl = Ax.gridlines(crs=Projection , draw_labels=True, linewidth=0.5, 
                  alpha=0.4, color='k', linestyle='--')

# For Cartopy <= 0.17
gl.xlabels_top = False
gl.ylabels_right = False
# For Cartopy >= 0.18
# gl.top_labels = False
# gl.right_labels = False

Fig.show()

Answer 2:

我终于成功地解决我的问题。 我用Ajdawson技巧，以做到这一点。 下面是解决方案的代码：

import matplotlib.pyplot as plt
import cartopy.crs as ccrs
import geopandas as gpd

Geopandas_DF = gpd.read_file('my_file.shp')

# setting projection and Transform
Projection=ccrs.PlateCarree()
Transform = ccrs.Geodetic(globe=ccrs.Globe(ellipse='GRS80'))

Fig, Ax = plt.subplots(1,1, subplot_kw={'projection': Projection})

Geopandas_DF.plot(ax=Ax, transform=Ax.transData)

gl = Ax.gridlines(crs=Projection , draw_labels=True,    linewidth=0.5, 
                  alpha=0.4, color='k', linestyle='--')

gl.top_labels = False
gl.right_labels = False
gl.xlabels_top = False
gl.ylabels_right = False

Fig.show()
