How to adjust the position of the x-axis ticks and put the angle degree on the values of the x-axis ticks?

7 views (last 30 days)
Dears, I have the following plot in Matlab as shown below:
The x-axis represents angles. I would like to add the angle degree, which is the small circle on the x-axis ticks, and I need to distribute the values of the x-axis elegantly, not, as shown above, they are close to each other. Any assistance, please?

% Use plot instead of semilogx to avoid the "scrunching" of the x axis
% semilogx(ThetaHalf,Vec_BEAM,'-dg',ThetaHalf,Vec_NOBEAM,'-^r',ThetaHalf,Vec_MIS,'-Oc','LineWidth',2,'MarkerEdgeColor','b')
plot(ThetaHalf,Vec_BEAM,'-dg',ThetaHalf,Vec_NOBEAM,'-^r',ThetaHalf,Vec_MIS,'-Oc','LineWidth',2,'MarkerEdgeColor','b')
xticks(ThetaHalf)
xlabel('\theta_1_/_2');
ylabel('Coverage area m^2');
legend('With Beam','Without Beam','Manual')
grid on;
xticklabels(compose('%d°', ThetaHalf)) % set x tick labels to include degree symbol

With all values in one decade, log plot gets pretty squished; you can set the xlim to just cover the actual range and then only use some of the x values as ticks instead of all.
But, switching to linear axis may be as good or better a solution unless there's some unstated reason for the log axis; I've shown both on two subplots; take your pick...
