Dear Rooters, I would like to ask a simple question I couldn't find the answer to in the manual. How do I draw a simple TGraph without getting that annoying line parallel to the x axis marking the y=0 position? I've tried with and without grid lines and the y=0 line is always there. Is there a simple way to draw a graph without it? I have taken a look at the tutorials pages but all examples with graphs have only y>0 values but in my case I have positive and negative values. So the y=0 line is not the x axis. I am sending attached a picture of a graph where the problem shows up. thanks, Henrique **************************************** State University at Campinas - BRASIL "Gleb Wathagin" Physics Institute Department of Cosmic Rays and Chronology Henrique Barbosa The Pierre Auger PhD Student Observatory ****************************************
