If you use function graphics (FG), then if you do something like

p = plot(x,y)
p = plot(x2,y2,/overplot)

you can save the generated plot in any of your required formats like so:

p.save, "plot.png"
p.save, "plot.pdf"

etc.

Same for other FG function like image, surface, etc.

The extension on the filename does all the hard work.

See http://www.exelisvis.com/docs/Save_Method.html

*BUT* - very importantly - if this question is in relation to your other
post, where you are generating many plots within a loop (using old style
direct graphics, DG), then ignore everything I said above and do what
DavidF suggested and use his Coyote Graphics (CG) tools.

Using function graphics in a loop will slow your script down by many
many orders of magnitude.
