Hi Eric,
Thanks for your help, I'm still really new to python and matplotlib. I've
got my labels defined but now I'm having another problem with the
formatting.
I'm doing -
CS1.level=[14.07, 14.27]
plt.clabel(CS1,CS1.level[::2],inline=True,fmt='OIII',fontize=14)
Where I get a type error that says that not all string arguments are
getting converted during formatting. This is the full error,
Traceback (most recent call last):
File "ContourAttempt.py", line 81, in <module>
plt.clabel(CS1,CS1.level[::2],inline=True,fmt='OIII',fontize=14) #
Something wrong with formmating
File "/Users/alexavillaume/src/matplotlib/lib/matplotlib/pyplot.py", line
2176, in clabel
ret = ax.clabel(CS, *args, **kwargs)
File "/Users/alexavillaume/src/matplotlib/lib/matplotlib/axes.py", line
7326, in clabel
return CS.clabel(*args, **kwargs)
File "/Users/alexavillaume/src/matplotlib/lib/matplotlib/contour.py",

line 284, in get_label_width
lev = self.get_text(lev, fmt)
File "/Users/alexavillaume/src/matplotlib/lib/matplotlib/contour.py",
line 344, in get_text
return fmt%lev
TypeError: not all arguments converted during string formatting

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
