Hi @aswinbio,

Since NDVI is a ratio you do not need to divide your results by 10000 before performing the calculation. Computing the NDVI with DN as inputs will produce the same results with some minor numerical differences due to precision (the resulting layer needs to be in float however).

You could also calculate NDVI directly in the Evalscript, saving you a calculation step (unless you have a good reason to request raw band values).

Thanks for the answer Maxim. I am getting weird plots and difference of min and max values are super high. I get a nice plot for NDVI if I normalize it using the maximum reflectance values.
