A quick-n-dirty way would be to use markers via the scatter() function.
Just set the facecolor to 'none', and some very large markersize value.

Hello,
how can I plot circles or other shapes in plots which have logarithmic
axis?
I have a grid of 3 plots and want to plot some kind of sketches in the
lower
right corner of
each subplot. How should I do that?
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import gridspec
fig = plt.figure(figsize=(6, 10))
gs = gridspec.GridSpec(3, 1, height_ratios=[1.5, 1, 1])#, height_ratios=[2,
1, 1])
ax0 = plt.subplot(gs[0])
ax1 = plt.subplot(gs[1])
ax2 = plt.subplot(gs[2])
plt.setp(ax_new.get_yticklabels(), visible=False)
plt.setp(ax_new.get_xticklabels(), visible=False)
ax_new = fig.add_axes([0,0,1,1], frameon=False,aspect=equal)
ax_new.axes.get_yaxis().set_visible(False)
ax_new.axes.get_xaxis().set_visible(False)
circle1=plt.Circle((0.2,0.0),0.05, color=0.8)
circle2=plt.Circle((0.4,0.0),0.05, color=0.8)
ax_new.add_artist(circle1)
ax_new.add_artist(circle2)
ax0.semilogx(x,x**2, k-, linewidth=2)
ax1.semilogx(x,x**3, k--, linewidth=2)
ax2.semilogx(x,np.exp(-x)+x**4, k-., linewidth=2)
plt.tight_layout()
plt.show()
