I am reading values from the sensor and I am getting values from 3.3576 to 4.0811 not exactly approximately.
so I want to scale these values to 1.4 to 4. So that I can do comparison with my data.

Suppose you have :
x=[3.35 3.4 3.8 3.9 4 4.08];
and you want to scale it to the interval [a b]
a=1.4;
b=4;
you can do it like this :
y = (x-min(x))*(b-a)/(max(x)-min(x)) + a;
y =
1.4000 1.5781 3.0027 3.3589 3.7151 4.0000
