我在玫瑰图上使用了 Plot vector（或 arc）的答案。MATLAB绘制我的玫瑰图，但我的情节如下所示：
我的代码：
circ_plot(BB,'hist',[],20,true,true,'linewidth',2,'color','r')
hold on
plot([0 cos(mean)*a], [0 sin(mean)*a], 'r')
%// Plot error as many shaded triangles that compose a circular wedge
t = linspace(-Var/2+mean,Var/2+mean,100); %// increase "100" if needed
for k = 1:numel(t)-1
h = patch([0 cos(t(k))*a cos(t(k+1))*a 0], ...
[0 sin(t(k))*a sin(t(k+1))*a 0], [.5 0 0], 'edgecolor', 'none');
%// change color [.5 0 0] to something else if desired. Note also alpha
set(h,'Facealpha',.3) %// make transparent
end
%// Place rose on top by rearranging order of axis children
ch = get(gca,'children');
set(gca,'children',[ch(2:end); ch(1)]);
任何想法如何让我的错误阴影区域遵循圆的圆周而不是三角形？
谢谢
