Grapher utility issues (Lion's fault?)

I'm having trouble with the Grapher utility and defining/graphing functions. If I define a function, say f(x) = x^2, and then try to graph a transformation of it, say y=f(x-2), Grapher displays only a graph of y = f(x). All transssformations within the function yield the same results; and transformations outside of the function behave as they should.

I am not sure if this is an issue with Lion, but I only saw the problem after I updated. Prior to that, there were no problems.

Thanks,

Hi,

Defining a function in Grapher 2.2 : the variable must not be x y r theta (never use 2D coodinates) ; tried now on a MacBook Pro 15" Lion Grapher 2.2.

Defining a function in Grapher 2.1 : the variable may be x y r theta (you may use 2D coodinates) ; tried now on a iMac 20" early 2006 Snow Leopard Grapher 2.1.

In your example use f(t) = t^2 and get correct curves y = f(x) and y = f(x-2)

It's new but not a bug. Is this change useful ? I must say functions look now quite different from curves equations.

So long,
