Hello,
I have the following histogram (normalised to maximum frequency) as shown:

How can I find the total area of the curve say area_tot from [-1 to +1] under the histogram and then only the areas from [-1 to -0.2] say area_1 and [+0.2 to +1] say area_2 ??
Please help.

Yes, I have found the solution. But what is the correct way of normalising any histogram?
1) normalise by max. freq 2) normalise by total area 3) normalise by sum of freqs?
Please advice.
