when you draw a figure, you need to set some parameters. After this, if I want
to draw another figure, my question is, how can I switch back to the default
parameters.... Is there a command for this. Thanks!

always use script and draw every plot in command line.
this would avoid most problems.

great. Thanks!
I think even in the script case, if you want to draw several graphes, this
command is still useful.
btw, gnuplot is really great...
Do you know that if it can draw steamlines, like in a fluid flow field?

want

sure. I am using gnuplot to draw streamlines. hoho :)
It's not trivial to plot streamlines in gnuplot. You need to plot every
lines by yourself. I mean every arrow. Once you have done that, gnuplot
can even beat tecplot. Because it is so fast and easy to use.;)

wow, that's really great...
Would you like to write a small tutorial about how to draw streamlines in
gnuplot? That'd be terrific...
There is one code that could draw vector field. It's called vect2gp. You can
get it here http://www-atm.physics.ox.ac.uk/user/hiro/
How do you think of it?

作图都是gnuplot作的,没什么,我看了他的code，看了一点儿，所以知道一些。
还有，他做animation的方法就更原始了.:)
