how to remove exponent notation after rfplot?

It seems rfplot has a fixed format. I want to use GHz at x axis label and remove the exponent label/notation shown in right bottom of the pic.

My code: S1 = sparameters('xxx.s2p');

s1=rfplot(S1,2,1,'r');

ax=gca;

ax.FontSize = 18;

ax.XAxis.Exponent = 9;

ax.XAxis.Label.String = 'Frequency (GHz)';

ax.YAxis.Label.String = 'S21 (dB)';

[KSSV]

ax.XAxis.Exponent = 9; I guess this is for the power 9...try changing this..

Hi there,

I am not sure if you have solved this problem, but I think there is a simpler way. You can take:

S1 = sparameters('xxx.s2p');

my_return_loss = rfparam(S1,1,1); % note the 1,1 is for s11. choose the one you need (i.e.s21). 

my_return_array_size = length(my_return_loss); 

a = 20 % GHz
b = 50 % GHz
frequency_array = linspace(a,b,my_return_array_size);

plot(frequency_array,20*log10(my_return_loss));

ax=gca;

ax.FontSize = 18;

ax.XAxis.Label.String = 'Frequency (GHz)';

ax.YAxis.Label.String = 'S11 (dB)';

Hope this solves your problem.

All the best, Cristian
