[Gnuplot-info] data precision

[sauber89 <sau...@ho...>]

Hello,

I want to normalize data, but it doesn't really work. I have the following
script:

------------------------------------------------
# Parameter
f_0 = 1.5e8
e_el = 1.6e-19
l_b = 10e-9
e_0 = 8.85e-12
l_w = 4e-9
e_b =10
e_w = 10
e_g = 3*e_el
h = 6.62e-34
m_0 = 9.109e-31
m_e = 0.3*m_0
m_h = 1.2*m_0

#Set label
set log x
set xrange [1e10: 10e18]

#Function computation
f_w(x) = f_0-x*e_el*l_b / (e_0* (l_w*e_b+l_b*e_w) )
E_max(x) = e_g-e_el*f_w(x)*l_w + (9*e_el*h* f_w(x) /(16*sqrt(2)))**(0.66) *
((1/m_e)**(0.33)+(1/m_h)**(0.33))

# plot without normalisation 
pl E_max(x) w l
pause mouse

# plot with normalisation
pl E_max(x)/e_el w l
pause mouse

#end
-------------------------------------------------

And I obtain these two following plots:

Normally, it should be the same curve with different scale?
