How to plot a single snapshot with plot_vertical_section?

[ThomasHaine]

I want to plot a vertical section at a single time (snapshot) using plot_vertical_section. How do I do it?
If I try:

ax = od_surv.plot.vertical_section(
    varName="ort_Vel", 
    contourName="Sigma0", 
    robust=True, 
    cmap="coolwarm", 
    cutout_kwargs={"timeRange":'2003-07-02T03'},
    contour_kwargs={"levels":contour_levels},
)

it gives two plots:

Here's one solution, which is an ugly hack!

from copy import deepcopy
od_moor_snap = deepcopy(od_moor)
od_moor_snap._ds = od_moor_snap._ds.sel(time = '2003-07-02T03',method = 'nearest')

ax1 = plt.subplot(4,1,1)
od_moor_snap.plot.vertical_section(
    ax = ax1,
    plotType = 'pcolormesh',
    varName="U",
    contourName="Sigma0",
    contour_kwargs = {'levels' : Sigma0_contour_levels},
    robust=True,
    cmap="cool",
)
(-od_moor_snap._ds['Depth'].squeeze()).plot(x='mooring_dist', color='k', lw=3)

Surely, there's a more elegant way?
