There is, I do it quite often. I have a routine in my IDL library
called swindow that makes a scrolling window. This is done using
a draw widget so may not work directly in PV-Wave but the basic idea
is simple to port. I've made windows as big as 5900 x 7100 pixels
to view a landsat image, and one 20,000 x a few hundred to view a
long time series.
Speaking of time series, this library also contains a number of
routines related to dates and times, including a time series plot
routine (called jsplot) that seems to do reasonable time axes over
ranges from a few minutes to a few years.
You can get the library as follows:
ftp fermi.jhuapl.edu
login: anonymous
password: your email address
cd pub/idl
get README
bye
The text file README describes what is in the libraries, how to
get them, and how to set them up.
A web page that has more information on this library may be found at
ftp://fermi.jhuapl.edu/www/s1r/idl/s1rlib/local_idl.html
This page has a link called "Dealing with time in IDL using the
JHU/APL/S1R library" which gives a more detailed description and
examples.
