Matplotlib projection remove margin

Question

Here\'s an image of US counties, created on top of

ax = plt.axes(projection=ccrs.LambertConformal())
ax.set_extent([-120, -70, 20, 50], ccrs.Geodetic())
<         


        

Answer 1

You can use subplots_adjust:

To remove all the whitespace from around the Axes object, use:

fig.subplots_adjust(left=0, right=1, bottom=0, top=1)

Setting the extent is changing the data limits, not the position/size of the Axes.
