If you're using IDL 6.2 or later, you can grab your command history
buffer, edit any necessary lines, and paste them back to the command
line.
A couple years ago I wrote a handy utility for managing the command history
buffer. It's available at
http://www.ittvis.com/codebank/search.asp?FID=350
When the command history window is in focus, you can edit the text, select
the lines you want to execute and copy them. Then switch focus to the
IDE command line and paste them in for execution.
When you find you have a group of commands that you execute often, paste
them into a .pro file and you've got the start of your very own utility
library.

I agree, I do the exact same thing, exploring through data. However, I
write
my commands in a small main level program, so I can always reproduce
it, and replot it very easily. I usually save off a copy if there is
something interesting
and increment the filename (datalook1.pro, datalook2.pro).
After getting a handle on the data, I use that code as a template for the
real analysis routines, which are always saved so I can always reproduce a
figure
(for a paper or whatever).
Cheers,
bob

Sigh...
You'll have to wait for my next book. But rest assured, it
involves objects and the "UNDO" method. :-)

Thank you guys. I tried the oplot method and it kind of worked. The
only setback is that it also erase a small portion of other plots if
there are intersections between two plots.
By the way, David, I am not a big fan of batch file...I just happened
to be using it because I just learned that new trick. So, please
please teach me if there is a proper way to undo plots...without batch
files. :P

They are rather hard to use in a batch file. ;-)

Also, I think that if you use the object-oriented graphing routines
(IDLGR?) you can re-do plots easily. I don't know though, I've never
used them.

Sometimes this works OK:
OPLOT, lastthingy, COLOR=!P.BACKGROUND
It's the poor man's way of erasing something.
