A fairly easy way is to do::
locs = ax.get_xticks()
labels = ['%1.2f'%(loc/1000. - 10.) for loc in locs]
ax.set_xticklabels(labels)
but this won't be updated when you pan and zoom. To do it right, use
a tick formatter::
import matplotlib.ticker as ticker
def format(x, pos=None):
return '%1.2f'%(x/1000. - 10.)
ax.xaxis.set_major_formatter(ticker.FuncFormatter(format))
