mpl hates my guts today.
I'm developing an application for work and need to plot some spectra on a
logscale. I can recreate my problem with embedding_in_qt4, by replacing
MyDynamicMplCanvas.compute_initial_figure with this:
def compute_initial_figure(self):
self.axes.plot([0, 1, 2, 3], [1, 2, 0, 4], 'r')
self.axes.set_yscale('log')
[...]
File
"/usr/lib64/python2.5/site-packages/matplotlib-0.90.1_r3709-py2.5-linux-x86_64.egg/matplotlib/axes.py",
line 1664, in set_ylim
raise ValueError('Cannot set nonpositive limits with log transform')
ValueError: Cannot set nonpositive limits with log transform
I get that error even if I modify the update figure function so there is no
possibility of zeros occuring in the data:
def update_figure(self):
# Build a list of 4 random integers between 0 and 10 (both inclusive)
l = [ random.randint(0, 10) for i in xrange(4) ]
l[l<=0]=1 # I love numpy
self.axes.plot([1, 1, 2, 3], l, 'r')
self.draw()
Anyone have any ideas? I think I have a bad case of gremlins.
