Below is a snippet of code from Brian Blaylock's True Color Recipe.  I am 
trying to instead display imagery in a Mercator projection. I thought I would 
do this with a line such as:
mc=cartopy.ccrs.Mercator(central_longitude=0.0, min_latitude=-80.0, 
max_latitude=84.0, globe=None)

and then have lines:
ax = fig.add_subplot(1, 1, 1, projection=mc)
ax.set_extent([-135, -60, 10, 65], crs=ccrs.Mercator())

but this does not work. Can someone point out what I am doing wrong or point me 
to the correct resource so I might understand my problem better?


Thanks, Jim

------ Code snippet ---------


fig = plt.figure(figsize=(15, 12))

# Generate an Cartopy projection
lc = ccrs.LambertConformal(central_longitude=-97.5, standard_parallels=(38.5,
                                                                        38.5))

ax = fig.add_subplot(1, 1, 1, projection=lc)
ax.set_extent([-135, -60, 10, 65], crs=ccrs.PlateCarree())

ax.imshow(RGB, origin='upper',
          extent=(x.min(), x.max(), y.min(), y.max()),
          transform=geos,
          interpolation='none')
ax.coastlines(resolution='50m', color='black', linewidth=0.5)
ax.add_feature(ccrs.cartopy.feature.STATES, linewidth=0.5)

plt.title('GOES-16 True Color', loc='left', fontweight='bold', fontsize=15)
plt.title('{}'.format(scan_start.strftime('%d %B %Y %H:%M UTC ')), loc='right')

plt.show()
