在matlab或excel中绘制三维条形图
我需要在matlab或Excel中绘制三维条形图。 我打算在x轴上使用一些date，在y轴上使用一些时间，在z轴上使用一些数量。 csv文件中的每个logging看起来像…

我不知道如何做到这一点。 任何人都可以帮助我。 我尝试使用excel的pivot图表。 然而，我不能操纵轴，并在每个刻度之间使用适当的空间。
谢谢kaisar
既然这个问题缺乏细节，让我举个例子来说明。
考虑下面的代码：
%# read file contents: date,time,value fid = fopen('data.csv','rt'); C = textscan(fid, '%s %s %f', 'Delimiter',','); fclose(fid); %# correctly reshape the data, and extract x/y labels num = 5; d = reshape(C{1},num,[]); d = d(1,:); t = reshape(C{2},num,[]); t = t(:,1); Z = reshape(C{3},num,[]); %# plot 3D bars bar3(Z) xlabel('date'), ylabel('time'), zlabel('value') set(gca, 'XTickLabel',d, 'YTickLabel',t) 我运行以下数据文件：
data.csv

使用MATLAB的CSV读取function （或自己写），然后使用bar3显示数据。
