Hi, In previous versions of Mathematica under Windows, you could read the x,y-coordinates of a point, say the min of x^2 + 5. You could measure the minimum by clicking on the graphics and paste it in an input cell for further processing. The coordinates were also displayed in the lower left corner of the window. With repeated steps one could get a lot of coordinates and fit them with e.g. NonlinearFit. How do I do it in Mathematica 6? I need this features badly for my students. -Reinhard -- ******************************************** Dr. Reinhard Simonovits Handelsakademie | Karl Franzens University Math Department | Inst. for Mathematics Grazbachgasse 71 | Heinrichstrasse 36 A-8010 Graz, Austria Email: Reinhard.Simonovits at uni-graz.at *********************************************
