labeling contours with roman numerals

This trick for replacing contour labels
with a string was posted a little while back (by someone else):

class FormatFaker(object):

def init(self, str): self.str = str
def
mod(self, stuff): return
self.str

A=arange(100).reshape(10,10)
CS=contour(A,[50,])
CS.clabel(fmt=FormatFaker(‘Some
String’))

Does a LineCollection generated by contour() have a property that

holds the labels? I would like to label my contour lines with roman
numerals, and cannot figure out how to get clabel to do that.

Thanks,

Mike

I’ve seen this, but I’m not clever enough to see how to extend that to multiple levels - after all, I don’t want to label every line with the same string…

I would guess:

CS=contour(A,[50,])
CS.clabel(fmt=FormatFaker(‘I’)) # Labels contour 50 with I
CS=contour(A,[60,])
CS.clabel(fmt=FormatFaker(‘II’)) # Labels contour 60 with II

Or write a loop if you have many values.
