I'm new to matplotlib. Currently the x-axis shows numbers from 0 to 1.
I would like it to show it in percent notation (e.g. 0% to 100%).
How do I do this in matplotlib?
Thanks,
Kevin

You can either multiply your x data by 100 (where x is a numpy array)
plot(x*100, y)
or set a custom formatter
from matplotlib.ticker import FuncFormatter
def myfunc(x, pos=0):
return '%1.2f''%(100*x)
ax = subplot(111)
ax.plot(x, y)
ax.xaxis.set_major_formatter(FuncFormatter(myfunc))
There is a section on custom tick formatting in the user's guide on the web site

And you may want to try:
def myfunc(x, pos=0):
return '%1.2f%%''%(100*x)
to get a percent sign after each value. (I mention it only because the "double percent" trick is non-obvious to many newcomers to Python's string formatting syntax.)
Cheers,
