My new graph ROP is created by me (casio2009), will share the tutorial soon! (on February, 20th)
Here are some result images:
1. Heart graph (newest version of graph that support f(x) and g(x).)

2. Meandered graph (using my older version, only support f(x). The formula I use here is y = f(x) = sin(10×x).)

3. Curved graph (using my older version, formula: y = f(x) = x².)

Stay tuned!
