I think that'd be fine -- i.e. the option of \cdot or \times (though in
the gmane preview the dot looks a bit low). In the mean time, I came up
with the method below that worked for my purpose.
Jon
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.ticker import FuncFormatter
def scinot(x,pos=None):
if x == 0:
s = '0'
else:
xp = int(np.floor(np.log10(np.abs(x))))
mn = x/10.**xp
# Here we truncate to 2 significant digits -- may not be enough
# in all cases
s = '$'+str('%.1f'%mn) +'\\times 10^{'+str(xp)+'}$'
return s
x = np.linspace(0.,2.,10)*1.E18
y = 2.*(x/1.E18) - 1.
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x,y)
ax.xaxis.set_major_formatter(FucFormatter(scinot))
plt.show()
