RE: Advanced Graphing error?
Hello,

I think that I know what is happening.

indeed, in the general case, X^Y is complex when X<0 and Y is not a rational.

HOWEVER, please remember that the advanced graphing does not treat pixels as 'points', but as 'areas'... And since Z is dense in R, in any area, there is an infinity of rational numbers. Hence, for any given pixel with X<0, this pixel will represent an infinity of rational numbers. And these rational numbers will have both positive and negative real roots (depending if the numerator is odd or even).

This is why you are seeing the 2 graphs in the X<0 space.
