To read the file you can do something similar to the examples proposed here:
–> in each files it is OK to delete the negative values in X axes, So the first value in file Data1 will be 0.272095635 and the first value in file Data2 will be 0.725269016. you can start with the smallest one.
–> about the limits of X axes will be as the small number of bins after deleting the negative values, in this case the number of the total bins will be (0 to 8182) according to the file 2.
–> i have a validity in the point of limits because the peak which i looking for located in he mi…
