Problems with ticks and grid lines when saving PDF

I'm trying to save a plot which consists of a linear scale on the Y axis and a Log scale on the X axis. I want minor grid lines and ticks on both of the axis. The plot is being saved as a PDF, the figures themselves have everything I require if view the plots in full screen but the PDF document only has the ticks and grid lines on the Y axis.

Here is the code that I am using to save the PDFs:

save_graph = '2024_Stress_Vs_life.pdf';

figure(1);

scatter(Mayer(:,1),Mayer(:,2), 45, 'd');

hold on;

scatter(UHCF(:,1),UHCF(:,2), 45, '+');

hold on;

scatter(Stanzel(:,1),Stanzel(:,2), 45, 's');

hold on;

scatter(Chen(:,1),Chen(:,2), 45, 'x');

hold on;

scatter(Lesperance(:,1),Lesperance(:,2));

hold on;

set(gca,'xscale','log')

title ('Fatigue Life of Al2024 Comparison');

xlabel('Number of Cycles');

ylabel('Stress (MPa)');

grid(gca,'minor')

grid on;

set(gca,'FontSize',20);

set(gca,'YMinorTick','on','YMinorGrid','on');

set(gca,'XMinorTick','on','XMinorGrid','on');

legend('Mayer','UHCF','Stanzel','Chen','Lesperance','Location','Best');

saveas(figure(1),save_graph);

I figured it out, I changed the orientation of the saved page and added tickmode manual on the X axis. Here is what the final code looks like:

save_graph = '2024_Stress_Vs_life.pdf';

figure(1);

scatter(Mayer(:,1),Mayer(:,2), 45, 'd');

hold on;

scatter(UHCF(:,1),UHCF(:,2), 45, '+');

hold on;

scatter(Stanzel(:,1),Stanzel(:,2), 45, 's');

hold on;

scatter(Chen(:,1),Chen(:,2), 45, 'x');

hold on;

scatter(Lesperance(:,1),Lesperance(:,2));

hold on;

set(gca,'xscale','log')

title ('Fatigue Life of Al2024 Comparison');

xlabel('Number of Cycles');

ylabel('Stress (MPa)');

grid(gca,'minor')

grid on;

set(gca,'FontSize',20);

set(gca,'YMinorTick','on','YMinorGrid','on');

set(gca,'XMinorTick','on','XMinorGrid','on','XTickMode','manual');

legend('Mayer','UHCF','Stanzel','Chen','Lesperance','Location','Best');

orient(figure(1),'landscape');

saveas(figure(1),save_graph);
