How to erase grid line

clear all

set(0,'DefaultAxesXGrid','on');
set(0,'DefaultAxesYGrid','on');
set(0,'DefaultAxesGridLineStyle','-');

 x = [125 250 500 1000];
 y = [1 2 4 3 ];
 semilogx(x,y,'*-');

 xx = num2cell(x);
 xticks(x)
 xticklabels(xx)

I want to keep solid grid lines but erase dotted grid lines .

How do I erase that?

there are also minor grid lines. use e.g.

set(gca,'xminorgrid','off')

to remove the minor x grid
