标题: 豆粑粑　matlab polarhistogram 极坐标的bar图
给小LY画图，用的是python 实现的，
我想在matlab中也实现一下。

1. clear all
   
2. clc
   
3. close all
   
4. % clf
   
5. 
   
6. theta = [0.1 1.1 5.4 3.4 2.3 4.5 3.2 3.4 5.6 2.3 2.1 3.5 0.6 6.1];
   
7. nbins = 6;
   
8. thetaBins = linspace(0,2*pi,nbins+1);
   
9. counts = histcounts(theta, thetaBins);
   
10. figure
    
11. tcl = tiledlayout(1,2);
    
12. nexttile(tcl)
    
13. polarhistogram(theta,nbins)
    
14. title('polarhistogram')
    
15. pax = polaraxes(tcl);
    
16. pax.Layout.Tile = 2;
    
17. hold(pax,'on')
    
18. % faceColor = turbo(nbins);  % choose your face colors
    
19. faceColor = jet(nbins);
    
20. for i = 1:numel(counts)
    
21.     polarhistogram(pax,'BinEdges',thetaBins(i:i+1),'BinCounts',counts(i), ...
    
22.         'FaceColor', faceColor(i,:), ...
    
23.         'FaceAlpha', 0.3, ...  % to match image in OP's question
    
24.         'EdgeColor','w')     % to match image in OP's question
    
25. end
    
26. title('loop')
    
27. 
    
28. h=gcf;
    
29. fi_na='./fig_polarhistogram';
    
30. fun_work_li_035_myfig_out(h,fi_na,3);
