Can I raed and write into an array simultaniously?

All the peak values will be negative. I am rounding them off so that they can be used in generating index of an array.

• If all values are negative, just mutiply by -60 and eliminate the "absolute value" function.
• The histogram is all integers, so make it blue (e.g. I32), no orange (DBL).

 Finally, Your suggestion of using a globally initialized node and using int32 in place of double worked out for me.  Thanx a lot.

I hope, I will also get to learn in future form You.
