Hi, Rooters I have the trouble with GetUymax(). After drawing histgram, we can usually get maximum value on the y-axis with the command "gPad->GetUymax()" Accutually I can get maximum value on the y-axis in interactive mode. root[1] gPad->GetUymax() The value is the same as one inspected in c1 window. But when I wrote "gPad->GetUymax()" in my program, I got "1" every time. This result from the difference between interactive mode and macro mode I do not know what to do to get right maximum value in macro mode. -- Takefumi SORA <tak-sora@bg7.so-net.ne.jp>
