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%: ####### : one :-0.08%: ## : short :+0.31%: ######## : two :+0.38%: ########### : val = [1,2,3,4] compare.doitall(lst,val) one :0.10%:###### : two :0.20%:############ : longest:0.30%:################### : short :0.40%:######################### :
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)

Here are the files. Compare.py is the actual file, example.py has some examples.
