Hi all,
I am new in the root program. I am facing some problems. Please help me by giving some suggestion. I have listed my problems in the following,
1.how to read data files one by one
2.how to display a calculated value of each data file in its corresponding graph? I tried with Tlegend but it can only display the line of the graph not any calculated value. Then tried with TPevtex and it also fails.
The data file is .Spe file and .txt file. There are many file in the folder but i want to read only all .Spe file or .txt file from the the folder. Please suggest me how i will do that.
Very likely the .txt files are ascii files. But what are the .spe files ? can you post one of them and we can try to show you how to produce a TGraph from it.
