plotting multiple vertical lines on a graph

Im currently using the code below to plot vertical lines on my graph at 0.5 intervals, but I want to change this to plot at every 0.25 intervals. It seems long winded to do this in this way, is there a more efficient way to do this?

figure(1)
cla;
scatter(x(:,a),y(:,a))
xlabel('X Coordinates')
ylabel('Y Coordinates')
title('Particle locations in the rice pile')
set(gca, 'XDir','reverse')
xline(0.08);
xline(0.085);
xline(0.09);
xline(0.095);
xline(0.1);
xline(0.105);
xline(0.11);
xline(0.115)
xline(0.12);
xline(0.125);
xline(0.13);
xline(0.135);
xline(0.14);
xline(0.145);
xline(0.15);

figure(1)
cla;
scatter(x(:,a),y(:,a))
xlabel('X Coordinates')
ylabel('Y Coordinates')
title('Particle locations in the rice pile')
set(gca, 'XDir','reverse')
L = 0.085:0.025:0.15 ; 
for i = 1:length(L)
    xline(L(i));
end
