Hi all,
I'm having trouble plotting functions were the domain aren't the real
numbers (R). Functions like x**-n, log(x), etc. Does anyone know if
there's a simple way of solving this problem. Here's a little script and
it's error:
from pylab import *
def f(x):
return log(x)
x = arange(-3, 4)
plot(x, f(x))
show()
Output:
Traceback (most recent call last):
File "test", line 7, in ?
plot(x, f(x))
File "/usr/lib/python2.4/site-packages/matplotlib/pylab.py", line
2019, in plot
ret = gca().plot(*args, **kwargs)
File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line 2111,
in plot
self.autoscale_view(scalex=scalex, scaley=scaley)
File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line 975,
in autoscale_view
if scaley: self.set_ylim(locator.autoscale())
File "/usr/lib/python2.4/site-packages/matplotlib/ticker.py", line
839, in autoscale
return take(self.bin_boundaries(dmin, dmax), [0,-1])
File "/usr/lib/python2.4/site-packages/matplotlib/ticker.py", line
809, in bin_boundaries
scale, offset = scale_range(vmin, vmax, nbins)
File "/usr/lib/python2.4/site-packages/matplotlib/ticker.py", line
783, in scale_range
ex = divmod(math.log10(-meanv), 1)[0]
OverflowError: math range error
Thanks!
