Not sure why legend annotations makes the problem different, but
perhaps this is a start:
$ python3

Thanks for your help, Alex, Roy and Jorge. I'm new to Python, and programming in general, which might explain my lack of knowledge, Fredrick. -- http://mail.python.org/mailman/listinfo/python-list

You can also use %g if what you want is fixed-point notation within a certain range and scientific notations only for numbers OUTSIDE that range, as in: >>> print '%g' % 10**5 10 >>> print '%g' % 10**50 1e+50 Alex -- http://mail.python.org/mailman/listinfo/python-list

No, I mean given a big number, such as 1000, convert it into scientific notation. -- http://mail.python.org/mailman/listinfo/python-list
