Hello list,
in the small example below with xscale and yscale logarithmic I'm not able to
set the xlabel inside the axes initialisation. The error output is attached.
It doesn't happen if I use the pylab command 'xlabel' or set one of the
scalings to linear.
Is this a bug or do I miss anything?
Thanks in advance for any hints.
regards Matthias

import matplotlib.pyplot as plt
ax = plt.subplot(111, autoscale_on=False,
xscale="log", yscale="log",
xlim=(1, 10**4), ylim=(10**-4, 1),
xlabel="logx",
)
#plt.xlabel('logx')
plt.show()
