A simple plotting example

A plotting example with a few simple tweaks

import numpy as np
import matplotlib

matplotlib.use("Agg")
import matplotlib.pyplot as plt

fig = plt.figure(figsize=(5, 4), dpi=72)
axes = fig.add_axes((0.01, 0.01, 0.98, 0.98))
x = np.linspace(0, 2, 200)
y = np.sin(2 * np.pi * x)
plt.plot(x, y, lw=0.25, c="k")
plt.xticks(np.arange(0.0, 2.0, 0.1))
plt.yticks(np.arange(-1.0, 1.0, 0.1))
plt.grid()
plt.show()
