And if I look at this on nabble the code looks fine, it just was not
redndering in inbox. Sorry, the issues is on my end.

Ok the last one got garbled.
My apologies to the list but here is another go.

Re: [Matplotlib-users] Help with updating the limits of an axis to reflect the range of new data
Can you include a minimal example of the code you are using (it looks like you did include code, but it did not come through)? It is very hard to guess at what is wrong without it.
