两行的X轴标签 [英] X-axis label on two rows

问题描述

str = {'HS31'; 'HS31 (Ridotto)';
    'Dax85';'Dax85 (Ridotto)';
    'FTSE89';'FTSE89 (Ridotto)';
    'SP98';'SP98 (Ridotto)';
    'Nikkei22';'Nikkei225 (Ridotto)';
    'SP457';'SP457 (Ridotto)';
    'Russ1318';'Russ1318 (Ridotto)';
    'Russ2151';'Russ2151 (Ridotto)';
    'Eurostoxx';'Eurostoxx (Ridotto)';
    'Ftse';'HS31 (Ridotto)';
    'Mibtel';'Mibtel (Ridotto)';
    'SP';'SP (Ridotto)';
    'Nasdaq';'Nasdaq (Ridotto)';

};
h=figure;
bar(t);
set(gca, 'XTickLabel',str, 'XTick',1:numel(str))

saveas(h, 'Backtesting/computing_time.png');

我看不懂情节下方的文字.你知道如何解决吗?

I can't read the text below the plot. Do you know how to fix it?

推荐答案

如果您可以将文本旋转90度，可以尝试使用基于非常有用的x标签旋转文本工具的此代码，该工具可用 here

If you are okay with 90 degrees rotated text, you may try this code that is based on a very useful x-label rotating text tool, available here

代码

h=figure;
bar(randi(9,26,1),'EdgeColor','g') %// Assumed random data for demo
set(gca, 'XTickLabel',str, 'XTick',1:numel(str))
xticklabel_rotate([],90,str);%% File-exchange code %// xlabel text rotated
saveas(h, 'computing_time.png');

带有一些随机数据的样本图

如果您可以对x-label文本进行下采样，例如，仅显示其他所有 标签，请在创建图形手柄之前使用此权限-

If you are okay with down-sampling the x-label text, i.e. for example show only every other label, use this right before creating the figure handle -

str(1:2:end)={[]}

其余代码保持不变.输出图看起来像这样-

Rest of the code stays the same. The output plot would look like this -

如果您仍然希望保持数据水平，则需要对标签数量进行适当的下采样.在给定的示例中，系数4起作用.代码中的更改是在声明str之后，当然在注释了x标签旋转工具的用法之后，添加了以下代码-

If you still want to keep the data horizontal, you need to downsample the number of labels by a good factor. In your given sample case, a factor of 4 worked. The changes in the code is adding the following code right after declaring str and of course commenting the x-label rotating tool usage -

str1 = cell(1,numel(str));
str1(1:4:end) = str(1:4:end);
str = str1;

这里的窍门是对要跳过的x标签使用空单元格.

The trick here is to use empty cells for the x-labels that you want to skip.

结果-
