Describe the bug

I have a tall skinny NDCube,

data = np.random.rand(4923,44,44)
wcs = astropy.wcs.WCS(naxis=3)
wcs.wcs.ctype = 'HPLN-TAN', 'HPLT-TAN', 'WAVE', 
wcs.wcs.cunit =  'deg', 'deg', 'm'
wcs.wcs.cdelt = 0.00012694444093439315, 0.00012722222341431512, 6.500000017695121e-14 
wcs.wcs.crpix = 0.0,  0.0,  1.0
wcs.wcs.crval = 0.0, 0.0,  1.799997462288593e-09
my_cube = ndcube.NDCube(data, wcs=wcs)

If I plot a single slice (in latitude), I see the x-axis has labels corresponding to the latitude and the y-axis corresponding to wavelength,

my_cube[:,0,:].plot()

However, if I plot a smaller section in wavelength space of the cube, the y-axis labels disappear

my_cube[950:1125,0,:].plot()
