Hi, thanks Ryan for the interest. Here is a short script to produce the data.
The method also breaks if I change too much the radius of the sphere or the
size at which they are plotted.
I am using:
Python 2.5.4
Matplotlib 0.98.5.2
Regards,
Code follows:
###############################################################
#!/usr/bin/env python
from matplotlib import pyplot as plt
import matplotlib.mlab as mlab
import numpy as np
NN=9
xmin=0.1
xmax=3.5
x= np.arange(xmin,xmax,.10)
y=np.square(np.sin(x))
# Creamos la figura
fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_yscale('log')
# Sphere radius (also radius and centers for all inner circles)
radio=.1
rads= radio*(1. - np.arange(0,NN)/(1.*NN))
dl= np.array([(radio-r) for r in rads])*radio
ylimits=(0.01,1.2)
for x1,y1 in zip(x,y):
ax.scatter(x1*(1+dl),y1+(y1*dl), cmap=plt.cm.Blues, c=rads,s=2500*rads,
edgecolors='none')
ax.set_xlim(xmin,xmax)
ax.set_ylim(ylimits)
plt.show()
