I have collected a set of points which i now want to include in a scatter diagram. The result was ok I used ListPlot[data] to do this However, some of the points were placed beneath the x-axis (these points did not have a negative y-axis value) The points were loaded as data={{1,18},{2,17.6},{3,14.5},{4,12.6},{5,12.5},{6,14}}; and the command for plotting the graph was plotdata=ListPlot[data,PlotStyle->PointSize[0.01]]; what i did next was try to fix the axes problem with AxesOrigin command which i set to 0,12 and what came out was the same graph but with no intersection of the axes The axes seemed not be be interesecting at any point Instead, at the point at which the axes should be intersecting there was blank space What could be wrong? 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 command and then i pasted the graph in a document in word Everything was fine until i tried to resize the object which had as a result the quality to change due to the fact that it was a bitmap My question about that is can i set the graphs in mathematica to be presented at a certain size so as to be consistent with the size that they will be presented in word? In other words is there any relation between the size of the graphs in mathematica and that of the pasted bitmap in word? How can i set a default size for the graphs i create? Why when i execute the copy (not copy as) and then paste the object in word the graph is presented at very small scale Notice that when i resize the particular pasted object (that is when i have only execute the copy command in mathematica) the quality is the same as in the notebook i.e. great! Why though is the size so small? What is the best solution in exporting a graph? I then tried to label the axes of the graph and i realised that the fonts in the graph were barely readable How can i change the size and/or the fonts IN the graphs? How can i make my changes to be default so as i wont need to change them everytime? I then tried to statistically analyse the set of points What statistical models (scalemethod) are available in mathematica? Where can i find them listed in the online documentation? Can i use the bestfit command for non-linear regression? Again what models are available in the nonlinearfit command and in what wasy can i use it for the data shown above? I appreciate your understanding on the fact that i have just begun to explore mathematica Your help will be most valuable for me Best regards Peter Manaras
