Hello Peter, consider g=Plot[x,{x,0,1}]. What you get from Format/Show Expression is not the same as g. g contains the mathematica commands to create the graphics. It does print as "-Graphics-", but you can look at g by e.g. FullExpression[g]. Show Expression on the other hand gives you postscript code that has been created from the expression in g that fits your output dives, here the screen. As you are not spefifying your problem, that is all I can say. hope this helps, Daniel P_ter wrote: > Hello, > I have a severe problem. > If I do in Mathematica 5.2: Plot[x, {x, 0, 1}], the result is just -Graphics-. > So clicking on the empty rectangle I get with Format Show Expression the following expression. Has anyone an idea what is wrong with it? Is it wrong? Any suggestion is welcome.
