Cartopy 0.17.0：当我设置central_longitude时，我不知道如何准确设置提供的范围：

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

projection = ccrs.PlateCarree(central_longitude=180)
ax = plt.axes(projection=projection)
ax.coastlines()
ax.set_extent((-120, 120, -45, 45), crs=ccrs.PlateCarree())
ax.gridlines(draw_labels=True, crs=ccrs.PlateCarree())

这正确地划分了纬度子集： 这正确地划分了经度子集，但有额外的标签：

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

projection = ccrs.PlateCarree(central_longitude=180)
ax = plt.axes(projection=projection)
ax.coastlines()
ax.set_extent((-120, 120, -45, 45))
ax.gridlines(draw_labels=True, crs=ccrs.PlateCarree())

这可以正确设置纬度：

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

projection = ccrs.PlateCarree(central_longitude=180)
ax = plt.axes(projection=projection)
ax.coastlines()
ax.set_extent((-120, 120, -45, 45), crs=projection)
ax.gridlines(draw_labels=True, crs=ccrs.PlateCarree())

当我尝试输入自己的代码时...

在较早的单元格中...

ticker = FixedTicker(ticks=range(0, 10))

在以下单元格中...

%%opts HeatMap [colorbar=True colorbar_opts={'ticker': ticker}]

我知道了

TypeError [Call holoviews.ipython.show_traceback() for details]
MetaModel object got multiple values for keyword argument 'ticker'

这是回溯...
