No Y. On the Acer Tablet can not access the left key area in function area. Makes this limited graph useless

Could find no way to scale axes independently. Not very useful if you can't do that. Cannot use physical keyboard to enter functions. No pinch and zoom at all.

It is good but bad thing is that it graphs of one variable. Like cirlce graph can not be drawn :(
by Q####:
Functions aren't plotted correctly. Some values are missing. Also the input keyboard is cut off. Please fix these. Tools aren't always working.
