Hi all, Does Ruby have any modules useful in graphing equations like y=x**2+5, y**2+x**2=16, 4y+3x=28, and the like? I suppose the two tasks involved are getting the points, and then graphing them. I'm on kind of a tight schedule so I hoped not to write either of those from scratch. Thanks SteveT Steve Litt http://www.troubleshooters.com slitt / troubleshooters.com
