 Hello,

  I have two objects of type TGraphErrors, let's say TG1 and TG2
 and I would like to divide them, e.g. TG3=TG1/TG2 and get 
 the correct error treatment. Is there an function for this
 operation which I overlooked ?

 ..or do I have to get the values at each point by GetPoint
 make the division, calculate the error, create new objects
 and set the points ?

 Thank you for you help.
