matlab - 使颜色条的框架变白，同时保持标签为黑色

Question

如何使颜色条框周围的矩形线变为白色，但使刻度标签保持黑色？

下面的可重现代码:

colormap(flipud(autumn(6))); % Create Colormap
         cb = colorbar; % Create Colorbar         
         cb.Ticks = [.1667 .3334 .5001 .6668 .8335]; % Create ticks
         cb.TickLabels = ({'0%','5%','10%','15%','20%'});    
         cb.TickLength = 0;
         cb.Color = 'w'; % Everything becomes white, I only want the rectangular color of the box to be white

Answer 1

您可以通过在颜色条上叠加一个白色注释框来获得想要的视觉效果，例如

    colormap(flipud(autumn(6))); % Create Colormap
             cb = colorbar; % Create Colorbar         
             cb.Ticks = [.1667 .3334 .5001 .6668 .8335]; % Create ticks
             cb.TickLabels = ({'0%','5%','10%','15%','20%'});    
             cb.TickLength = 0;
             % cb.Color = 'w'; % Everything becomes white, I only want the rectangular color of the box to be white

    annotation('rectangle',cb.Position,'Color','w','FaceColor','none','LineWidth',2)
