Does anyone know how to fix this problem ? Both graphs I'm dealing with,
negmu_ptb & posmu_ptb are good as far as I’m aware & draw fine, but
when I try to divide them using the command line interpreter I hit problems.
root  negmu_ptb->Divide(posmu_ptb)
Error: Symbol posmu_ptb is not defined in current scope (tmpfile):1:
*** Interpreter error recovered ***
