It's a bit weird that you can't just take an algebraic expression off the stack and just plot it...

Did you try Carsen's 81 MENU suggestion? I think it's exactly what you're looking for. If you assign << 81 MENU >> to a key, then it'll be available in one keystroke. Once menu 81 is showing, you have STEQ available right there (left-shift EQ) as well as ERASE (optional, to clear any previous plot), DRAX (optional, to draw the X & Y axes), and DRAW (creates the graph).

For your example, with '2*X^3' on the stack, just press STEQ DRAW to create the graph you desire. (Include ERASE and DRAX as desired). There's even a handy PPAR soft key in menu 81 which lets you check and set the graphing parameters. And a PTYPE soft key to set the plot type. Menu 81 is your friend.

Like i said in my reply to Carsen, he did answer my question and his solutions obviously work. I was referring to the ability to do it "out of the box". It was just a remark, not a complaint. I could have been a bit clearer, to be honest.

Thank you.
