I started the first tutorial example and got this "hello, world", and then I looked into the menus. Then I searched "root files" but this was empty (grmpf). At some time, I got a core dump (Linux/lesstiff 0.77). I restarted root and ... ofcourse: the same way run the hello-world example from the tutorial (I didn't read much more there :-(), and the root file (created with h2root) was there in a subdir .../home/ole/Root/j123.root But, when I clicked at one of the left buttons, this icon vanished and I didn't get it back. So I had to restart it again... In the meantime I got the mail that I can use "TBrowser B", ok this is faster. Then just clicking on the directory name, then on the file name and there I got my hists. Maybe, the root tutorial should (for stupid people like me) not start with programming but with a chapter "How can I explore my histograms with root?". This should contain: - h2root usage - TBrowser B - where to find the files I want - just the basics what happens with the left, middle (???) and right click of the mouse. > > How can I zoom in a histogram? I didn't find the option for it. > What did you mean? The hists go from (x axis) -500 to 500. The interesting region for me in only -10 to 10.
