Display contour & circle

from matplotlib import pyplot as plt

from py_eddy_tracker import data
from py_eddy_tracker.observations.observation import EddiesObservations

Load detection files

a = EddiesObservations.load_file(data.get_demo_path("Anticyclonic_20190223.nc"))

File was created with py-eddy-tracker version '3.4.0+39.gf81199a.dirty' but software version is '3.6'

Plot the speed and effective (dashed) contours

fig = plt.figure(figsize=(15, 8))
ax = fig.add_axes((0.05, 0.05, 0.9, 0.9))
ax.set_aspect("equal")
ax.set_xlim(10, 70)
ax.set_ylim(-50, -25)
a.display(ax, label="Anticyclonic contour", color="r", lw=1)

# Replace contours by circles using center and radius (effective is dashed)
a.circle_contour()
a.display(ax, label="Anticyclonic circle", color="g", lw=1)
_ = ax.legend(loc="upper right")
