Just apply a linear transformation of the data range [Ymin, Ymax] to [0, 1] ... simple!

Hello Gayathri, Please go through this code i have given for your reference sake and this will help you 

range = max(a) - min(a);

a = (a - min(a)) / range;

range2 = y - x;

a = (a*range2) + x;

Many ways and depends on direction

a- Min (a)/ Range

or  Max (a) - a/ Range

or  making standard normal variate.
