画图中进行程序运行时提示转义字符无效，更新legend时出错

  • 你看下这篇博客吧, 应该有用👉 ：matlab legend换行 多个legend 阵列排布
  • 除此之外, 这篇博客: 【Matlab】根据excel画折线图和柱状图中的 添加图例（legend） 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:

  • legend：legend('legend1', 'legend2', 'legend3')

    %% prepare data in excel
data_file = 'data.xlsx'

%% read data from a certain sheet
data1 = xlsread(data_file, 1); % first sheet
data2 = xlsread(data_file, 2); % second sheet

%% plot
% plot1 = plot(data1(1:end,1:end),'DisplayName','data(1:end,1:end)');

%% bar
bar2 = bar(data2(1:end,1:end),'DisplayName','data(1:end,1:end)');

%% x label
xlabel('Event log');
% xlim([2.5 5.5])
% set(gca,'XTick',[2.5:0.5:5.5])
set(gca,'Xticklabel',{'\it{uci\_labour}','\it{uci\_weekends}','\it{102\_labour}','\it{102\_weekends}','\it{104\_labour}','\it{104\_weekends}','\it{110\_labour}','\it{110\_weekends}'}); %设置横坐标
set(gca,'XTickLabelRotation',45); 


%% y label
ylabel('Percentage');
ylim([0 1.0]);
set(gca,'YTick',[0:0.5:1.0]);
set(gca,'Yticklabel',{'Percentage(0%)','Percentage(50%)','Percentage(100%)'});
set(gca,'YTickLabelRotation',45); 

%% plot with markers
% set(plot1(1),'marker','+');
% set(plot1(2),'marker','*');
% set(plot1(3),'marker','o');

%% plot with different specific colors
% set(plot1(1),'color',[255/255 247/255 235/255])
% set(plot1(2),'color',[237/255 177/255 32/255])
% set(plot1(3),'color',[153/255 51/255 0/255])

%% bar with different colors
set(bar2(1),'facecolor',[0.87 0.92 0.98])
set(bar2(2),'facecolor',[0.73 0.83 0.96])
set(bar2(3),'facecolor',[0.39 0.47 0.64])

%% legend
lege = legend('Second', 'Minute', 'Hour');
