Topic: Independent x and y zooming
Hi, I love your program, and I use it a lot in my Calculus classes. My suggestion is to have separate zoom buttons for changing the scale on only one axis at a time. I think this would be really useful for helping to explain limits at infinity, and infinite limits. I know it can be done by changing the axis parameters, but it's a little more cumbersome to do in front of a class. Thank you!
