Re: [Matplotlib-users] Newb: can I plot() just once but render/save to disk different "zooms"?

[Michael D. <md...@st...>]

Once you have an axes object, you can call set_xlim() and set_ylim() on 
it to change the limits of the x- and y- axes respectively.  You should 
be able to call that and savefig() iteratively to produce plots of 
different subsets of the same data.

Let me know if you need more details,
Mike
