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

  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')

  28. h=gcf;
  29. fi_na='./fig_polarhistogram';
  30. fun_work_li_035_myfig_out(h,fi_na,3);

这是直接用polar bar的方式画,不用统计.
