Bug summary
Sometimes, LogLocator draws fewer ticks than it can due to less than optimal log stride selection.
Code for reproduction
from pylab import *
# At this figure size there's room for two y ticks
# (check with ax.yaxis.get_tick_space())
# which could be placed e.g. at 10^0 and 10^4,
# but only one tick is drawn at 10^2.
figure(figsize=(5, 1)).add_subplot(yscale="log", ylim=(.5, 15000))
Actual outcome
See comment above.
Expected outcome
See comment above.
Additional information
I suspect that the formulas for stride and decades in LogLocator.tick_values() are faulty.
