Remember when challengers were fun?

The last 10 challenges I have seen were useless challenges, that seemed like the op was just trying to get us to do his homework for him.

Remember challenge 5 when we got to make our own toy language? Or challenge 8 where we got to create a text based battle system? That shit was fun.

I demand a real challenge now.

These challenges are not even a month old. If you are getting nostalgic about these shitty challenges then I daresay you need to return to /g/ post haste.

Are you serious? These challenges are over 3 months old.

If you are saying that I should go back to /g/ then I daresay Fuck off, ``faggot''!

Storlek's language one was the last serious challenge. The battle system one was turned serious by the entrants (Xarn), but wasn't intended to be one. The person who posted it didn't even bother to come back to announce the winner.
It's probably possible to turn most lame joke challenges into serious ones by entering a serious entry.

But yeah, a good new challenge would be nice.

CHALLENGE:

In a language of your choosing, write a program that takes a mathematical function and window size variables (i.e. Xmin, Xmax, Xscl, Ymin, etc.) as input
and outputs BBCode that produces a graph of the function when posted to /prog/.
