MATLAB颜色条刻度标签中的错误? [英] Error in MATLAB colorbar tick labeling?

问题描述

我正在绘制9个子图，如下图所示，其中一个色条表示三个子图.

I am plotting 9 subplots as shown in figure below with one color bar for three subplots.

在这里，我想在色条中将最大值显示为> value，令人惊讶的是，当我手动将刻度标签编辑为h.TickLabels{end} = ['>' h.TickLabels{end}];时，色条开始重复该值.

Here I want to show the highest value in color bar as > value, surprisingly when I manually edit the tick label as h.TickLabels{end} = ['>' h.TickLabels{end}]; the color bar starts repeating the value.

当我删除h.TickLabels{end} = ['>' h.TickLabels{end}];时，颜色栏显示没有问题.当我更改set(gcf, 'PaperUnits', 'inches', 'PaperPosition', [0 0 8 8])中的图形大小时，随着[0 0 5 5]彩条标签再次更改.

When I remove h.TickLabels{end} = ['>' h.TickLabels{end}]; the color bar show no problem. When I change the figure size in set(gcf, 'PaperUnits', 'inches', 'PaperPosition', [0 0 8 8]) as [0 0 5 5] colorbar labeling again changes.

如何解决此错误?

下面是我的工作示例和输出图像:

Below are my working example and output image:

data = [1 2 3; 5 7 3; 12 29 14; 1 7 3; 2 8 3; 5 4 1; 2 2 1; 2 3 1; 1 5 2];
for i=1:9
    subplot(3, 3, i)
    plot(data(i,:));
    if ismember(i, [1:3])        
        caxis([0 20])
        if i==3
            h = colorbar('Fontsize', 6, 'LineWidth', 0.15, 'TickDirection', 'out',...
                         'TickLength', 0.02);
            set(h, 'Position', [.935 .6867 .01 .2533])
            h.TickLabels{end} = ['>' h.TickLabels{end}];
        end
    end
    if ismember(i, [4:6])       
        caxis([0 6])
        if i==6
            h = colorbar('Fontsize', 6, 'LineWidth', 0.15, 'TickDirection', 'out',...
                         'TickLength', 0.02);
            set(h, 'Position', [.935 .3733 .01 .2533])
            h.TickLabels{end} = ['>' h.TickLabels{end}];
        end
    end
    if ismember(i, [7:9])        
        caxis([0 4])
        if i==9
            h = colorbar('Fontsize',6, 'LineWidth', 0.15, 'TickDirection', 'out',...
                         'TickLength', 0.02);
            set(h, 'Position', [.936 .06 .01 .2533])
            h.TickLabels{end} = ['>' h.TickLabels{end}];
        end
    end
end
set(gcf, 'PaperUnits', 'inches', 'PaperPosition', [0 0 8 8])
print('test', '-djpeg', '-r300')
close all

推荐答案

如 Sardar所写，这是解决问题的唯一选择这会自动执行，并且在更改图形窗口大小时不会丢失刻度的自动缩放，而是添加侦听器.这是这样做的方法:

As Sardar wrote, the only option to solve this automatically, and not lose the auto-scaling of the ticks when the figure window size is changed is to add a listener. This is how to do it:

将以下函数复制到m文件，并将其保存在此图所用的文件夹中(即当前路径):

Copy the following function to an m-file, and save it in the folder you work on this figure (i.e. your current path):

function set_cb_lables
% add '>' to the last tick label in all colorbars

h = findobj(gcf,'Type','Colorbar'); % get all colorbars handels
set(h,{'TickLabelsMode'},{'auto'}); % change thier mode to 'auto'
tiklbl = get(h,{'TickLabels'}); % get all tick labels after the change
for k = 1:numel(tiklbl) 
    tiklbl{k}{end} = ['>' tiklbl{k}{end}]; % add '>' to the last tick
end
set(h,{'TickLabels'},tiklbl); % replace the current ticklabels with tiklbl
end

然后，在您的代码中，在循环之后添加此行:

Then, in your code, add this line after the loop:

set(gcf,'SizeChangedFcn','set_cb_lables'); % aplly the function 'set_cb_lables' upon any size change

在调整图形大小后，这将自动在最后一个刻度标签上添加>".

This will add '>' automatically to the last tick label upon any resizing of the figure.

此解决方案比在添加'>'之前先获取刻度更好，因为现在如果窗口变大，则会自动在色条中填充更多刻度.

This solution is better than just getting the ticks before adding the '>' because now if the window gets bigger, the colorbar is populated automatically with more ticks.
