    I have an fx-9860gii, I'm new to it. I recently tried out an fx-cg10 and find that I could zoom in and out of a graph using the + and - buttons. It seems like the fx-9860gii won't let me do this, are there any options (addins, programs...) to allow this?

     Thanks.

I don't think so.

 

You can change to graph zoom by pressing OPTN > ZOOM > IN

and you can also change the graph zoom by changing the viewport values

 

But I don't know of any way of zooming using the +/- buttons. But I will check with my calculator soon.

Hi, there is not an easy way to do that, but if you really want to do it, you have to write a program in Casio Basic with the GetKey and ViewWindow commands.
