Dear All, In my datafile (a converted hbook file) I have the coordinates of conversion point in an event. I would like to plot these in order to see what dead material is there (of course I know this, but just to check the data). The most simple option to do this is, of course, a simple Draw statement. Something like: TFile f = new TFile("./other/dis96_06.root"); h1.Draw("y_conv:x_conv","conditions blah"); However, I then get a plot in which the axes run from -80 to 80, for both the x and the y axis. I would like a detailed plot of the range -40 to 40, also both on the x and y axis. I found a type on how to do this, however, this doesn't seem to work. Can anybody please tell me how I should do this. Thanks, Sven Schagen
