```Greetings!

You can actually accomplish this using MetPy's `StationPlot` class. A basic
example of using this for a standard 2D plot is here:

https://unidata.github.io/MetPy/latest/examples/plots/Station_Plot.html#sphx-glr-examples-plots-station-plot-py

and the full documentation of this class is here:

https://unidata.github.io/MetPy/latest/api/generated/metpy.plots.StationPlot.html#metpy.plots.StationPlot

`StationPlot` works just fine for plotting on any axis coordinates, not just
spatial, so you can use it with standard matplotlib timeseries plots, as done
in this example code:

from datetime import datetime, timedelta
import matplotlib.pyplot as plt
from metpy.plots import StationPlot, current_weather
import numpy as np

# Create some dummy data, including WMO codes for current weather
cur_wx_codes = [65, 85, 95, 99, 54, 57, 59, 67, 88, 82, 79, 75]
dummy_y_vals = np.zeros(len(cur_wx_codes))  # only to place on plot
dates = [datetime.utcnow() + timedelta(hours=i) for i in
range(len(cur_wx_codes))]
temps = np.random.randn(len(dates)) * 10 + 70

# Create a plot using matplotlib's StationPlot
fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
sp = StationPlot(ax, dates, dummy_y_vals)
ax.plot(dates, temps)
sp.plot_symbol('C', cur_wx_code, current_weather, fontsize=16, color='red')

Hope this helps,
