gnuplot
gnuplot is a graphing program that integrates extremely well with LaTeX and thus prosper, if you do it right.
In gnuplot
set terminal pslatex
set output "myfile.tex"
set format xy "$%g$"
# if in 3D
set format z "$%g$"
Use latex in your title/labels etc - but you need to escape the backslash.
IE
set title "Over Approximation for\n$a=4$, $b=2$, $h=3$, with $\\Delta y=0.5$"
The '$\\Delta y=0.5$'
gets spit to the output tex file as '$\Delta y=0.5$'
so that the Delta gets properly drawn.
In your preamble, use
\usepackage{pslatex}
To include the gnuplot tex output - in your document just use
\input{myfile}
The real neat thing about doing it this way - as you play around with type of prosper style you want, as the fonts change in color - so will the fonts on your gnuplot generated images.
Not only will the mathematical formulas in your slideshow look better than anything anyone using PowerPoint can produce, but your graphs will look a hell of a lot better as well.
