I was playing around today, and I made a little python script that can graph functions in the terminal. It could be nicer, but I'm happy enough with it. Here's some sample output:

It can graph functions from 0 to any number (you'd want a limit so it doesn't wrap). This is a graph of sin(x)

compare.functiontogrid(function=lambda x:math.sin(x),maxx=6,scale=10,marks=15)

It can do a comparison bar-graph to visually compare numbers. It has three modes, and can handle negative numbers.

lst = ["one","two","longest","short"]
val = [-1,5,-3,4]
compare.doitall(lst,val)

longest:-0.23%:                         #######                               :

The last thing it can do is graph scatter plots

nums = range(20) + range(20) + range(20)
x = random.sample(nums,50)
y = random.sample(nums,50)

out = compare.coordstogrid(x,y,marks=6)
