how do I graph asymptotes in Excel
 

If I have x values in col A and y values as the function =((3*A1)+2)/(A1-3),
....
Ahh, I think I just found it, where the denominator is the unknown number
(DIV/0), in this case x=3, leave an empty row for the x and y values. That
got rid of the annoying connecting line that crosses the horizontal and
vertical asymptotes shown in the XY Scatter with smooth lines chart. Hope
this helps someone else. Thanks.
