Special graph properties

hi
I have a few more questions…

  1. How is it possible to get Markers like in the picture (the long black lines) because in TAttMarker I found only point like styles…
  2. how is it possible to set particle names like pi or eta on the x-axis? instead of other labeling…
  3. How can I change the label-step size of an axis, if I want for example only the highest and the lowest value (10 and 0 instead on 10,9,8,7,6,5,4,3,2,1).
  4. is there a good tutorial where I can find all this stuff, because there are only a few tutorials in the internet available and all of them are very basic…
    thanks for help
    best regards
    florian

All the available markers are listed here: root.cern.ch/root/html/TAttMarker.html

see:
$ROOTSYS/tutorials/graphs/labels1.C
$ROOTSYS/tutorials/graphs/labels2.C

Change the number of divivions:
Graph->GetXaxis()->SetNdivisions(502);

$ROOTSYS/tutorials.

An other good way to learn all this is to modify the canvas ouput interactively and save the result in a .C file (menu File/Save in the canvas). This technique makes sense only if you do before View/Editor.
