Hello matplotlib developers, In Sage, we've run into a problem with plotting a sequence whose y-values change by very small amounts. Here's an example that doesn't use anything from Sage:
import pylab
pylab.plot([0, 1], [0, 1e-14])
pylab.savefig("works.png")
pylab.close()
pylab.plot([0, 1], [1, 1+1e-14])
pylab.savefig("fails.png")
pylab.close()
We're using matplotlib 1.1. Here's a trac ticket where we are working on
this: http://trac.sagemath.org/sage_trac/ticket/11973. One of our
developers suspects matplotlib.ticker.MaxNLocator.bin_boundaries but we
don't really know.
Thanks for any help or comments!
Dan
