With the code given below to create a scatter plot and edit the legend marker size:
scatter(LE,pred_D,300,'b','o');
scatter(LE,measured_D,300,'r','d');
[~, hobj, ~, ~] = legend({'Predicted','Measured'},'Fontsize',12,'FontName', 'Arial','Location','Best');
M = findobj(hobj,'type','patch');
set(M,'MarkerSize',sqrt(600));
xlabel('$E^*/\sqrt{v^*}$','Interpreter','latex');
ylabel('Melt pool depth (μm)');
set(gca, 'FontName', 'Arial', 'FontSize', 12);
I am able to obtain the following output:
I intentionally have these larger marker sizes as Matlab seems to reduce them drastically when I use settings inside of File>Export Setup such as the ones given below:
These "Export Setup" settings make the scatter points ready for publication, but the legend seems to misbehave (changes size and marker thickness) as shown below:

The same Export Setup settings work well with the gscatter code:
pPlot=gscatter(v_star,E_star,melting_mode,'kbrm','so^d',20,'on','Dimensionless Velocity','Dimensionless Heat');
l= findobj(gcf,'tag','legend'); set(l,'location','northwest');
[hleg,att] = legend('show');
with before/after "Export Setup" images shown below:
