Is there any to plot a function and interactively move the viewport around like a TI84?

I have been using the basic plot(x,y) function in octave.  It works great but I was wondering if there was a way to get a plot like in a TI84 calculator.  You input a function like Y1 = 2X^3 and then you can plot it.  You can change the viewport to zoom out and in and pan around the graph.  You don't have to specify the data you want plotted, the entire function appears.  Is there anything like this in octave?  There isn't anything like this in the plotting documentation.  

Thanks for any responses,

Zach
