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

[David C. <dl...@ha...>]

Hi,

I just emigrated from Ploticus last week :)   Am working on a project where 
I'm plotting the contents of a large .csv file with about 250,000 cells
(unix system 5-minute load averages from a set of 50 servers, for about 
three weeks data now). 

I'm developing this in Spyder/Python(x,y)--completely unknown to me until 
last week--and the pan/zoom capability makes me wish/wonder two things:

1: I wish I could interactively save the zoomed view to disk, and

2: This behavior hints at the possiblity of a better way to go back 
and plot 15 1-day views of the original plot, than slicing up the 
source array and re-plotting.


I'm .. so new to matplotlib/numpy that I'm sure I'm missing some 
key concepts/terminology that, once identified, will let me find my 
way to what I need to know.   For example, I'm terribly confused right 
now by Axes.get_axes().

Which classes/methods/examples/gallery examples should I look at?

Thanks.
