Dears, I have the following plot in Matlab as shown below:
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1145650/image.jpeg)
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')

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...
