Set the PlotRange-option. This will do what you want: plotdata=ListPlot[data,PlotStyle->PointSize[0.01],PlotRange->{{0,6},{12,18}}]; > Furthermore I experienced some problems when > exporting the graph to another application in this case microsoft word > What i did was execute the copy as bitmap Why a bitmap ?

There are so many versions in Matheamtica 3.0, here is one with 12 pt Times Bold Italic: plotdata=ListPlot[data,PlotStyle->PointSize[0.01],PlotRange->{{0,6},{12,18}}, AxesLabel->{"some x-values","some y-values"}, TextStyle->{ FontFamily->"Times", FontSize->14, FontSlant->"Italic", FontWeight->"Bold" } ]; > How can i make my changes to be default > so as i wont need to change them everytime? Place : SetOptions[#, TextStyle->{ FontFamily->"Times", FontSize->14, FontSlant->"Italic", FontWeight->"Bold"}] & /@ {Plot, ListPlot, Graphics, ParametricPlot} in your init.m file and be sure that it tis the right one. > > I then tried to statistically analyse the set of points What statistical > models (scalemethod) are available in mathematica? Look in the nice book "Mathematica 3.0 Standard Add-on Packages" that comes with Your Mathematica copy. > Where can i find > them listed in the online documentation? You will be surprised it is in Main Menu | Help | Help ... | Add-ons | Standard Packages | Statistics > Can i use the bestfit command > for non-linear regression? What is the "bestfit" command ? Fit[] can only used in linear models. > Again what models are available in the > nonlinearfit command and in what wasy can i use it for the data shown > above? Mathematica is a Computer Algebra so You can use any mathematical combination of the special functions implemented in Mathematica. > I appreciate your understanding on the fact that i have just > begun to explore mathematica Your help will be most valuable for me Hope that helps Jens
