Are you expecting the plot like the picture attached from the xls data given?

I don't about the last attached image...but with your phase amp.png and attached xl file. Run the below code.
clc; clear all
file = 'example_alumi.xlsx' ;
[num,txt,raw] = xlsread(file) ;
phase = num(:,1) ;
amp = num(:,2) ;
loop = linspace(-10,10,length(num));
figure
subplot(211)
plot(loop,amp,'r')
ylabel('Aplitude')
subplot(212)
plot(loop,phase,'b')
ylabel('Phase Shift')
xlabel('loop')
