Plot rain attenuation model in MATLAB

I would like to plot the rain attenuation model based on ITU-R P.838-3 Recommendation as shown in the graph Rain Attenuation Graph

I tried to used "rainlp" command in MATLAB but I could not get the same graph.

clear all;clc
freq=[1:1000]*1e9;
Rr=[0.25, 1.25, 5, 25, 50, 100, 150]; 

for i=1:7
    L=rainpl(10000,freq,Rr(i));
    plot(freq/1e9,L)
    hold on
    grid
end

Any ideas how to get this graph by MATLAB?

Thanks in Advance
