semilogy seems to only work once

Hi all,

I’m making multiple semilogy histograms, which for now are on separate figures and not in subplots. Here’s something patched together:
def makehistogram(data,strtitle, filename):
fig = Figure()
pylab.hold(False)
pylab.semilogy(base=10)
n, bins, patches = pylab.hist(data, 50, normed=1)
pylab.setp(patches, ‘facecolor’, ‘g’, ‘alpha’, 0.75)
pylab.xlabel(‘bins’)
pylab.ylabel(‘logP’)
pylab.title(strtitle)
pylab.grid(True)
pylab.savefig(filename,dpi=72)

The first call to makehistogram() saves the semilogy histogram I want, but the subsequent calls create regular cartesian histograms. Am I missing something?

Thanks

with hold=False, the axes is reset whenever something new is added to
the axes. Instead of using pylab.hold(False), clear the figure or axes
explicitly (clf() or cla())
