After talking to Tech Support today I was able to get a short term fix for a problem that I have encountered. Example: Plot the equation y=x^2 and show boundaries at x=1 and x=2 (vertical lines). Is there an easy way to do this? The problem could also be asked where you need to use implicit plotting ImplicitPlot[x=y^3,{x,0,3}] and have y horizontal lines at y=1 and y = 2. Any suggestions? So far I only have the following: Show[Graphics[Line[{{1/2,-1,{1/2,8}}]], DisplayFunction -> Identity] Plot[x^2,{x,0,2},DisplayFunction -> Identity] Then combine the previous Out[] which in this case was Out[10] Graphics, and Out[11] Graphics Show[%10,%11, DisplayFunction -> $DisplayFunction] Larry Smith larry.smith at clorox.com 601-939-8555 extension 255 ==== [MESSAGE SEPARATOR] ====
