Advanced Visualization

Example: using matplotlib axes to extend plotting capabilities

By passing an axes handle to view() you can take advantage of all plotting features from matplotlib.

from mecode import G
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.patches import Rectangle

g = G()

g.feed(1)

g.toggle_pressure(1)
g.serpentine(25, 5, 1, color=(1,0,0))
g.toggle_pressure(1)

g.teardown()

fig, ax = plt.subplots()
ax = g.view('2d', ax=ax)
ax.set_xlim(-5, 30)
ax.set_ylim(-2, 5)
ax.add_patch(Rectangle(
    (0,0), 25, (5-1)*1, lw=5, ec='dodgerblue', fc='none',  alpha=0.3)
    )
plt.show()
