從matlab中的數字到數據的條形圖變化x軸

Question

我想問我怎樣才能改變數字1,2,3,4 ...從圖形，我想日期（1 - > 11_08_2016_12_36沒有.mat）在圖中來自工作區fnames.name中的變量。我嘗試了一些函數句柄，但它不起作用。謝謝你的幫助。

Code

Answer 1

N={fnames.name}; %isolate the names 
t=zeros(1,length(N)); %reserve space 
for ct = 1:length(N) %go over the names 
    temp=regexp(N{ct},'\d\d_\d\d_\d\d\d\d_\d\d_\d\d','match'); %match the relevant part 
    t(ct)=datenum([temp{:}],'mm_dd_yyyy_HH_MM'); %convert to datenum 
end 
%plot your graph here, use t as the x-axis% 
datetick('x',1) %give x-axis in date 

Answer 2

使用軸手柄。

data=rand(3,1); 

hfig = figure; 
hax = axes; 
hbar = bar(1:3,data); 
dates={'Date 1';'Date 2';'Date 3'}; 
hax.XTickLabel=dates; 
% In case you want your labels rotated. 
hax.XTickLabelRotation=90;
