Hi,
use numpy to calculate the upper and lower limits first?
curves = np.random.randn(1000, 10)
plt.fill_between(np.arange(1000), curves.min(1), curves.max(1))
hmm. I am not sure what you mean exactly. In my case i've got following function:
def pdf(x,s1,s2,p):
return (p/(math.sqrt(2*math.pi*s1**2))*numpy.exp(-((x-0)**(2)/(2*s1**(2)))))+((1-p)/(math.sqrt(2*math.pi*s2**2))*numpy.exp(-((x-0)**(2)/(2*s2**(2)))))
and s1,s2 and p are varying... so i have a list like
123, 3215, 0.3
152, 2351, 0.4
521, 4351, 0.6
...
for these three parameters. So the resulting curves are probably intersecting each other and are of different shape.
so two questions:
1) what is the best way to supply this list to produce the single curves (about 10)
2) how can I do the fill between to get the "range" of the curves. Maybe you can give me a more detailed example.
Thanks
