The semilogy plot doesn't show the grid lines ?

Hi !

I have been working with my code, earlier it plotted fine the BER curve with semilogy but now when I added another case to semilogy it plots the curve fine but the it doesn't show the grid lines of semilogy.

Any kind of help would be appreciated. Currently I am getting the plot as this in the image in the attachment.

grid on  % both x- and y-axes

or

set(gca,'YGrid','on')

for only y-axis.

Make sure to specify the grid after you use the semilog command.

x = [1:1:100];
y = [1:10:1000];
figure('Name','semilog plot')
hold on
fontsize(16,"points")
hold off
semilogx(x,y)
hold on
grid on
semilogx(x,y)
hold off
