I am able to successfully create a Basemap of the US within a Jupyter Notebook complete with shapefile, coloring, and borders in Cell 4.
I am trying to plot many data points onto this Basemap with the following line in Cell 8:
m.plot(x, y, marker='o', markersize=data, color='#444444', alpha=0.8, latlon=True)
The data gets plotted, but I lose all of my Basemap's formatting and shaping. Effectively, I want Cell 8 overlayed on Cell 4. I suspect I am not plotting these shapes on the same plane.
Additionally, plt.show() gives me nothing. What am I missing?
回答1:
A. using a figure instance
The idea can be to explicitely specify the axes to plot to at Basemap creation.
Cell 1:
fig, ax = plt.subplots()
m = Basemap(... , ax=ax)
Cell 2: # do other stuff
Cell 3:
# plot to map:
m.plot(...)
Cell 4:
# state figure object to show figure (when inline backend is in use)
fig

B. let pyplot not close figures
The other option would be to let pyplot not close the figures. This is the second option from this answer: How to overlay plots from different cells?
%config InlineBackend.close_figures=False
